The primary particles are electrons with the energy of 2.15\,MeV shooted
into the first scintillator. There the electron can be scattered, and therefore
it may or may not hit the second scintillator. We have used the command\\[2ex]
{\tt /musr/command storeOnlyEventsWithHitInDetID 11}\\[2ex]
and therefore only the events, in which there was some energy deposited
in the second collimator, will be saved into the output Root file.
To run this example, do the following:
\begin{enumerate}
\item Change to the directory {\tt musrSim/run/}
\item If the subdirectory {\tt data} does not exist, create it.
\item Run your Geant4 initialisation script (typically something like \\
{\tt source /home/install/geant4.9.4/env.sh}\\
where the path to the {\tt env.sh} script depends on the directory where Geant4
is installed on your computer.
\item Execute the command {\tt musrSim 101.mac}
\item The example file {\tt 101.mac} will try to visualise the events using the
Dawn graphics program. To simulate some data (without the visualisation),
uncomment the line {\tt /vis/disable}, comment the line
{\tt /control/execute visDawn101.mac} and change number of generated events
to e.g.\ 1000 (by command {\tt /run/beamOn 1000}).
\item Look at the output using Root, e.g.\ by commands \\
{\tt \$ root} \\
{\tt root [0] TFile* f2=new TFile("data/musr\_101.root") } \\
{\tt root [1] .ls } \\
{\tt root [2] t1->Print() } \\
{\tt root [3] t1->Draw("det\_edep","det\_ID==10") } \emph{\small //energy deposited in the first scintillator}\\
{\tt root [4] t1->Draw("det\_edep","det\_ID==11") } \emph{\small //energy deposited in the second scintillator}\\
{\tt root [5] t1->Draw("det\_time\_start[0]-det\_time\_start[1]")} \emph{\small //T.O.F. between the two scint.} \\
{\tt root [6] .q}\\
Note that the hits in one event are ordered according to the deposited energy, and therefore the
first hit sometimes corresponds to the hit in scintillator counter 10, sometimes to the hit in counter 11.
Therefore the histogram created by the command {\tt t1->Draw("det\_time\_start[0]-det\_time\_start[1]")}
has two peaks -- at a positive and at a negative time.
\end{enumerate}

\section{Example 2 -- Sr decay electrons passing through two scintillator tiles (102.mac)}
This example is very similar to the previous one. The only difference is that initial
particles are decay electrons from a $^{90}$Sr source. Because $^{90}$Sr decays to $^{90}$Y,
which in turn also decays emitting an electron, we have in fact two decay electrons per event
(two emission spectra from the strontium source).
The data for the strontium and yttrium decay are taken
from the Geant4 data files, namely\\
{\tt /home/install/data\_geant4.9.4/RadioactiveDecay3.3/z38.a90}~~~~ and\\
{\tt /home/install/data\_geant4.9.4/RadioactiveDecay3.3/z39.a90}. \\
There is, however, one problem in musrSim -- it has to handle times with picoseond precission,
and the \emph{double} precision used in the c{\tt ++} program is then not enough to deal with
the $^{90}$Sr decay time of 29 years.
For this reason, one has to modify the decay times in the two data files, i.e.\
in the file {\tt z38.a90}, one should replace the line\\
\hspace*{1cm}{\tt P~~~~~~~0.0000~~~9.0820e+08}\\
by the line\\
\hspace*{1cm}{\tt P~~~~~~~0.0000~~~9.0820e-08}\\[2ex]
and in the file {\tt z39.a90}, one should replace the lines\\
\hspace*{1cm}{\tt P~~~~~~~0.0000~~~2.3080e+05}\\
\hspace*{1cm}{\tt P~~~~~682.0300~~~1.1480e+04}\\
by the lines\\
\hspace*{1cm}{\tt P~~~~~~~0.0000~~~2.3080e-05}\\
\hspace*{1cm}{\tt P~~~~~682.0300~~~1.1480e-04}\\
This way, the decay times are reasonably short, and musrSim can handle them.
Another complication comes from the fact, that the decay electrons are emitted
isotropically from the Sr source. In principle, it is possible to restrict the
emission angles in the GPS (General Particle Source), but we have not done this
intentionally, because we did not want to exclude events in which the decay electron
enters a counter after scattering in the air. In the end only a very small fraction
of events hits the second counter, and is written out to the output file.
(In any case -- the events in which electron does not enter any counter are simulated in a much
shorter time than the ``interesting'' events.)
The example {\tt 102.mac} is based on the results published in~\cite{kkkkk}.

\section{Example 3 -- Simulation of the light transport (103.mac)}
This example is similar to example~1, and extended by the simulation of light (``optical
photons''). The light simulation slows down the execution of musrSim dramatically.
The simulation of light is a new feature in musrSim, and it is being tested. Once
this is finished, we will improve this example. However, it seems to be running fine
in its current implementation, so you can start using it. A lot of usefull information
about the optical photons is given in chapter ``Optical Photon Processes'' in
the Geant4 User Manual~\cite{geantUserManual}.\\

\section{Example 4 -- GPD instrument (201.mac)}
%
The General Purpose Decay-Channel Spectrometer (GPD)
instrument~\cite{GPD} at PSI, more or less as implemented in reality in the year 2010, is exemplified in
run {\tt 201.mac}. GPD instrument is optimised for the measurements of pressuarised samples
in a special pressure cells.
The detector system is relatively simple -- it consist of a rectangular muon counter (10x10x2\,mm),
two backward positron counters, three forward positron counters, cylidrical sample in a cylindrical
sample holder, two lead collimators, one copper collimator, GPD magnet, and some additional ``dead'' material.
The GPD geometry is illustrated in Fig.~\ref{fig:vis_201_1}-\ref{fig:vis_201_4},
where some of the elements present in the simulation (beampipe, magnet, aluminium profiles) are not displayed
for simplicity.
The most important parameters of the simulation are summarised in table~\ref{dimensions}.

A non-standard feature of this simulation is the muon momentum, which is $~sim$100\,MeV/c.
The copper collimator used in GPD has a bit complicate shape, which required to use subtraction
of logical volumes in Geant\,4. This operation can not be specified through the macro file,
and therefore a special kind of volume called {\tt GPDcollimator} has been hard-coded into
the source code (namely in the routine {\tt musrDetectorConstruction.cc}), and it is
then activated in the macro file using the command \\[2ex]
{\tt /musr/command construct GPDcollimator \ldots}\\[2ex]

The results of this GPD simulation are described in the \emph{musrSimAna} manual~\cite{musrSimAna}.

\section{Introduction}
\label{introduction}
The purpose of the \musrSimAna\ program is to analyse the Root tree, the output
of the \musrSim\ program.
In general, the event-by-event information stored in the Root tree can be easily used only for
a very quick and rough tests -- e.g.\ to see, where the muons stop and decay irrespective
of whether they were triggered in the M-counter or not, or to have an idea what energy
spectrum was deposited in a given counter. Typically, however, one is more interested
to study \musr\ signal amplitude, time-independent background, or where the muons decay
only for the ``stopped'' muons (e.g.\ muons triggered by M-counter and not detected
by a veto counter), or only for triggered muons which actually stopped in a cryostat
rather than in a sample. Such a study requires some kind of analysis program, which
loops over all events stored in the Root tree (output of \musrSim), and implements the
logic of the required \musr\ experiment.
One way to do such analysis is to start from a Root command {\tt MakeClass(``MyAnalysis'')},
which creates some sort of skeleton c++ class for the given Root tree. This allows the user
to make his/her own and very specific analysis program tailored to his/her needs. On the other
hand, it requires special program for each detector set-up.
A second possibility is to use \musrSimAna, which is intended to be a general analysis
program for \musr\ instruments.
At the moment, however, \musrSimAna\ is tuned to the needs of continuous muon beam facilities.
Some modifications might be necessary for the pulsed muon beams.
As in the case of \musrSim, the user of \musrSimAna\ specifies all parameters
required by the analysis in an input text file (steering file). The initial structure
of the steering file was taken over from the TDC setup files used by real \musr\ instruments
at PSI~\cite{acquisitionProkscha,TDCsetup}. This setup file defines the ``logic'' of a given experiment,
namely the coincidences and anti-coincidences of different counters and veto detectors, as well as some
timing parameters.
The setup file for the case of simulation had to be extended by the definitions of
histograms, cuts, fitting, etc. The description of the setup file will be
presented in chapter~\ref{howToAnalyse}-\ref{description}, the chapter~\ref{sec:GPD}
illustrates the whole concept of \musrSimAna\ on the example of an existing \musr\ instrument.
\section{The main components of the \musrSimAna\ setup file}
\label{howToAnalyse}
The parameters for the analysis are stored in the setup file ``{\tt RUNxxx.v1190}'', whose name
typically consists of the run number ({\tt RUN}),
some further identifier ({\tt xxx}), and ends with ``{\tt .v1190}''.
One of the following commands can be used to execute \musrSimAna: \\[1em]
{\tt
\$> musrSimAna RUN RUNxxx \\
\$> musrSimAna RUN RUNxxx nographic > data/RUN.RUNxxx.out
}\\[1em]
where the first {\tt RUN} stands for the run number (more precisely, it specifies
the \musrSim\ output, which is expected to be stored as ``{\tt data/musr\_RUN.root}'')
and {\tt RUNxxx} specifies the \musrSimAna\ setup file without the ending, which is
expected to be stored in the current directory. The output file of \musrSimAna,
containing the result histograms, will be stored as ``{\tt data/his\_RUN\_RUNxxx.v1190.root}''.
The syntax of the setup file in \musrSimAna\ is based on the experimental one,
defined in~\cite{TDCsetup}.
At the beginning of this file, some timing parameters are defined:\\[1em]
\begin{tabular}{ll}
{\tt RESOLUTION=100 } & \emph{\ldots one TDC bin corresponds to 100\,ps} \\[0.7em]
{\tt MCOINCIDENCEW=50 } & \emph{\ldots time interval (in TDC bins) to find coincidences with M-counter} \\
{\tt PCOINCIDENCEW=50 } & \emph{\ldots time interval (in TDC bins) to find coincidences with P-counter} \\
{\tt VCOINCIDENCEW=100 } & \emph{\ldots time interval (in TDC bins) to find anti-coincidences with M-counter} \\[0.7em]
{\tt MUONRATEFACTOR=0.089 } & \emph{\ldots will be described in section~\ref{sec:eventMixing}} \\[0.7em]
{\tt DATAWINDOWMIN=-2.0 } & \emph{\ldots data interval (in $\mu$s) in which positrons are detected} \\
{\tt DATAWINDOWMAX=10.0 } & \\[0.7em]
{\tt PILEUPWINDOWMIN=-10.0 } & \emph{\ldots the pileup interval (in $\mu$s) for muons} \\
{\tt PILEUPWINDOWMAX=10.0 } & \\[1em]
\end{tabular}
%
A good event has exactly one hit in the M-counter within the pile-up window, and exactly
one hit in the positron counters within the data window. Both windows are defined relative to $t_0$,
which is the time of the currently analysed M-counter hit.
The coincidence and anti-coincidence logic between the different counters
(the detector logic) is also specified in the setup file.
An example may look like this:\\
\begin{verbatim}
102; "M up"; M; 0.4; 2005; -401;
1; "B1"; P; 0.4; 2005; 21 -401; B1; 1485; 1515; 50995;
2; "B2"; P; 0.4; 2005; 22 -401; B2; 1485; 1515; 50995;
11; "F1"; P; 0.4; 2005; -401 -21 -22; F11; 1485; 1515; 50995;
12; "F2"; P; 0.4; 2005; -401 -21 -22; F12; 1485; 1515; 50995;
13; "F3"; P; 0.4; 2005; -401 -21 -22; F13; 1485; 1515; 50995;
21; "Coinc B1" K; 0.4; 2005;
22; "Coinc B2" K; 0.4; 2005;
401; "Active Veto" V; 0.1; 2005;
\end{verbatim}
\mbox{} \\
%
In each row, the first number stands for the detector ID (defined in the steering file
of the \musrSim), the second variable is the name of the counter,
the third variable identifies the type of the counter (M = muon, P = positron,
K = coincidence and V = veto counters, respectively), the forth variable is the threshold in MeV applied
to the energy deposited in the counter, the fifth variable is a time delay (in units
of bin-width) applied to the given counter, the sixth set of parameters defines
which other detectors have to be in coincidence (positive ID) or anti-coincidence
(negative ID) with the given counter, and in the case of positron counters, the
last four parameters define a special histogram for the given counter. (Note
that this histogram is used for a compatibility with the experimental steering file, however
there is a different and more powerful way of how to define histograms, which is
defined later). The only difference with respect to the experimental steering
file is the presence of threshold definition in the fourth column.
In the example above, the M-counter is the volume which has ID 102 in the simulation,
and a valid hit has to have energy in the counter above 0.4\,MeV, and no signal
above 0.1\,MeV in the ``Active Veto'' (ID=401) within a time interval defined by
{\tt VCOINCIDENCEW}. The detailed description of *.v1190 steering files can be found
in chapter~\ref{description} and in~\cite{TDCsetup}.
The main output of the simulation is generated in the form of histograms.
The histograms are defined in the steering file. For example, the following
line defines 1-dimensional histogram of the $z$-position of where the muons stop and decay:\\[1em]
{\tt
musrTH1D hMuDecayPosZ "Where the muons stop;z[mm];N" 100 -5. 5. muDecayPosZ
}\\[1em]
This histogram has 100 bins, spans from -5\,mm to 5\,mm, and the variable filled
in the histogram is {\tt muDecayPosZ}.
In fact, this line does not create one histogram, but an array of histograms -- one
histogram for each ``condition''. An example of five conditions reads:\\[1em]
{\tt
condition 1 oncePerEvent \\
condition 2 muonDecayedInSample\_gen \\
condition 4 muonTriggered\_det \\
condition 6 goodEvent\_det \\
condition 9 pileupEvent
}\\[1em]
where integer numbers (1,2,4,6 and 9) denote the condition number, and the string at the end
describes the condition -- e.g.\ ``{\tt muonDecayedInSample\_gen}'' specifies that muon
has stopped and decayed in the sample, and ``{\tt muonTriggered\_det}'' specifies that
there had to be a good muon candidate triggered in the M-counter.
The ending ``{\tt \_gen}'' indicates that the variable used in the condition
was ``generated'', i.e.\ it is known in the simulation, but can not be directly
measured experimentally.
On the other hand the ending ``{\tt \_det}'' specifies that the given condition
is based on measurable variables, as e.g.\ energy deposits in a counter.
There can be up to
30 conditions requested, and for each of them a separate histogram will be filled.
In the output file of \musrSimAna, the histograms corresponding to the previous
set of conditions would be saved as
{\tt hMuDecayPosZ\_1, hMuDecayPosZ\_2, hMuDecayPosZ\_4, hMuDecayPosZ\_6, hMuDecayPosZ\_9}.
The {\tt hMuDecayPosZ\_1} shows where the muons stop irrespective whether they were
detected or not. The {\tt hMuDecayPosZ\_6} contains ``good'' muons, i.e.\ muons that would
be saved in the final histograms in the experiment. The {\tt hMuDecayPosZ\_9} shows
the muons, which contribute to the time-independent background. Note that there are always
two muons, $\mu_1$ and $\mu_2$, contributing to the time-independent background, and {\tt hMuDecayPosZ\_9}
shows the one ($\mu_1$) that started the M-counter. More to this topic is presented
in chapter~\ref{sec:eventMixing}. Here we just mention that in order
to see the $z$-coordinate of the second muon ($\mu_2$),
which was not triggered by the M-counter but whose decay positron hit the positron counter,
the histogram {\tt hpileup\_muDecayPosZ\_9} must be used:\\[1em]
{\tt
musrTH1D hpileup\_muDecayPosZ "Pileup muons;z[mm];N" 100 -5.0 5. pileup\_muDecayPosZ
}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\section{Event mixing -- an unavoidable complication}
\label{sec:eventMixing}
The output of \musrSim\ is stored in a Root tree named ``{\tt t1}''. One event corresponds
to one simulated muon, and it is saved as one row of the tree. The only information that
relates one event (muon) to any other one is the variable {\tt timeToNextEvent},
which is a randomly generated time difference between two subsequent events.
The \musrSimAna\ allows one to study the ``time-independent background'', which is
due to mixing of two different events. A simple example of the event mixing affecting
the \musr\ measurement is the following: the first muon, $\mu_1$, hits the M-counter,
and subsequently stops and decays in the sample, however the decay positron escapes
undetected -- most likely because of the limited angular acceptance of positron counters.
The second muon, $\mu_2$, arrives around the same time, misses the M-counter,
and stops and decays in a collimator wall or elsewhere.
Its decay positron hits a positron counter. Thus there are good-looking muon and positron
hits, which however arise from two uncorrelated muons.
This fake (background) event is experimentally treated as a good event,
and contributes to the time-independent background.
Events can be mixed in \musrSimAna, allowing us to study sources of
the time-independent background.
%\emph{MusrSimAna} loops over the events and checks whether the conditions defining
%the detector logic in the steering file have been fulfilled. However, to take event
%mixing properly into account, the conditions have to be veryfied on several subsequent
%events. Therefore, at the beginning of the analysis of
Before analysing a given event, arrays of hits are filled
for all counters (M, positron, veto, coincidence counters), which store the hits occurring in the
future up to the time equal to $ 3\, \cdot $ pileup window or $ 3\, \cdot $ data window,
whatever is larger\footnote{The data and pile-up windows defined by parameters
{\tt DATAWINDOWMIN, DATAWINDOWMAX, PILEUPWINDOWMIN} and {\tt PILEUPWINDOWMAX}
are applied later on in the analysis.}.
There is one such array for every counter. After this initial filling,
there might be several hits in every array, originating from one or more events.
The fraction of the time-independent background to good events depends on the incoming muon rate
measured by the trigger, possibly in the anti-coincidence with a backward veto detector, if
used in the experiment.
Typically, the experimentalists set the incoming muon rate (rate of \emph{stopped muons})
to $\sim 30\,000\,\mu/s$. The same should be done in the simulation.
However, the rate of stopped muons is known only after the analysis is done,
because, for example, many simulated muons stop and decay in collimators or elsewhere
in the beam-pipe without producing any signal in the M-counter.
Therefore the simulation is normally started with an initial rate of generated muons
of $30\,000\,\mu/s$, which in practise can correspond to much lower rate of \emph{stopped muons}.
The rate of stopped muons is calculated at the end of the \musrSimAna\ execution, and
it is printed out in the \musrSimAna\ output. The user can use this information and rescale the
initial muon rate by changing parameter {\tt MUONRATEFACTOR} in the {\tt *.v1190} setup file.
This is done without the necessity to re-run the CPU consuming
simulation -- only the \musrSimAna\ has to be repeated. The complete simulation and analysis
chain therefore usually consists of three steps:
%
\begin{enumerate}
\item \musrSim\ (takes typically 10 hours).
\item \musrSimAna\ with {\tt MUONRATEFACTOR=1.0} (takes typically 10 minutes).
\item \musrSimAna\ with {\tt MUONRATEFACTOR} determined in step 2.
\end{enumerate}
%
The {\tt MUONRATEFACTOR} specifies a multiplicative factor applied to
the variable {\tt timeToNextEvent}
(the randomly generated time difference between two subsequent events).
{\bf IMPORTANT NOTE:} In order to get the pile-up effects correctly analysed by \musrSimAna,
it is probably necessary to run the \musrSim\ with no event reweighting (i.e.\
the command ``{\tt /musr/command logicalVolumeToBeReweighted \ldots}'' must {\bf not} be used).
All events should/have to be (?) saved in the Root tree
(i.e.\ the command ``{\tt /musr/command storeOnlyEventsWithHits false}'' must be used).

\begin{description}
% \item{\bf INSTRUMENT=\emph{string}} \\
% ignored
% \item{\bf DESCRIPTION=\emph{string}} \\
% ignored
% \item{\bf TYPE=\emph{string}} \\
% ignored
\item{\bf RESOLUTION=\emph{value}} \\
width of the TDC bin in picoseconds.
\item{\bf MDELAY=\emph{value}} \\
currently not used (probably not needed in the case of simulation).
\item{\bf PDELAY=\emph{value}} \\
currently not used (probably not needed in the case of simulation).
\item{\bf MCOINCIDENCEW=\emph{value}} \\
time window for the coincidences of the coincidence detectors (``K'')
with the M-counter. The \emph{value} is given in TDC bins (see {\tt RESOLUTION} above).
\item{\bf PCOINCIDENCEW=\emph{value}} \\
time window for the coincidences of the coincidence detectors (``K'')
with positron counters. The \emph{value} is given in TDC bins.
\item{\bf VCOINCIDENCEW=\emph{value}} \\
time window for the coincidences of the anti-coincidence detectors (``V'')
with any other counter. The \emph{value} is given in TDC bins.
\item{\bf MUONRATEFACTOR=\emph{value}} \\
a multiplicative factor which is used to rescale time differences between subsequent muons.
Setting \emph{value} larger than 1 artificially prolongs the time difference between
two subsequently generated muons, and therefore decreases the incoming muon rate
(number of muons per second). This parameter should be changed in order to set the
incoming muon rate to a given required value, typically to 30\,000\,$\mu/$s.\\
See also variable ``INFINITELYLOWMUONRATE''.
\item{\bf INFINITELYLOWMUONRATE} \\
If INFINITELYLOWMUONRATE is specified, each event is treated independently of any other
event. This corresponds to a situation of infinitely low rate of incoming muons, and
no pileup can be observed. The variable ``MUONRATEFACTOR'' becomes irrelevant when
INFINITELYLOWMUONRATE is specified.
\item{\bf DATAWINDOWMIN=\emph{value}} \\
Beginning of the data interval for the positron counters in $\mu$s.
\item{\bf DATAWINDOWMAX=\emph{value}} \\
End of the data interval for the positron counters in $\mu$s.
\item{\bf PILEUPWINDOWMIN=\emph{value}} \\
Beginning of the pileup interval for the M-counter in $\mu$s.
\item{\bf PILEUPWINDOWMAX=\emph{value}} \\
End of the pileup interval for the M-counter in $\mu$s.
\item{\bf MUSRMODE=\emph{string}} \\
Defines the mode of \musr\ experiment -- presently only ``D'', corresponding to
the time differential mode is implemented.
\item{\bf REWINDTIMEBINS=\emph{value}} \\
A technical parameter specifying when a roll-over of all hits has to be done.
It is specified in TDC bins, and normally there should be no need to change this parameter.
\item{\bf DEBUGEVENT \emph{eventID} \emph{debugLevel}}\\
Prints out debug information about the event with the ID \emph{``eventID''}.
The higher the \emph{debugLevel}, the more details are printed.
(Both \emph{eventID} and \emph{debugLevel} are integers).
\item{\bf CLONECHANNEL \emph{ID1} \emph{ID2}}\\
Clones the hits detected in counter \emph{ID1} into a new counter \emph{ID2}.
A different (even a lower) threshold can be applied to the cloned counter.
This way the same counter can be used as two independent counters -- e.g.\ once as a veto
detector for the M-counter, and simultaneously as a coincidence detector for
a P-counter. In both cases the energy threshold and time windows are defined independently.
\item{\bf musrTH1D \emph{histoName} \emph{histoTitle} \emph{nBins} \emph{min} \emph{max} \emph{variable}
[{\tt rotreference} $\nu_{\rm RRF}$ $\phi_{\rm RRF}$]} \\
Defines a histogram (or more precisely an array of histograms, where the number of histograms
in the array is given by the number of conditions, see section~\ref{howToAnalyse}).
The name of the histogram is defined by \emph{histoName} + the number of the condition.
The string variable \emph{histoTitle} specifies the title of the histogram,
\emph{nBins}, \emph{min} and \emph{max} stand for the number of bins and minimum and maximum
of the $x$-axis of the histogram. \\
The optional keyword ``{\tt rotreference}'' signals that the given histogram will be filled in
rotating reference frame (RRF) with the frequency of $\nu_{\rm RRF}$ and a phase shift of $\phi_{\rm RRF}$.
\\
The \emph{variable} stands for the variable that will be
filled into the histogram. The \emph{variable} can be any variable from the output Root tree
of musrSim (see ``Manual of musrSim'') (except for the array variables like
{\tt det\_*[], save*[], odet\_*[]}). In addition, it can be also one of the following:
\begin{description}
\item[muDecayPosR] \ldots $\sqrt{ {\rm muDecayPosX}^2 + {\rm muDecayPosY}^2}$.
\item[wght] \ldots weight of the event.
\item[det\_m0edep] \ldots energy deposited in the M-counter that gives the muon signal.
\item[det\_posEdep] \ldots energy deposited in the P-counter that gives the positron signal.
\item[pos\_Momentum] \ldots magnitude of the momentum of the decay positron (``generated'', not measurable variable).
\item[pos\_Trans\_Momentum] \ldots transverse momentum of the decay positron.
\item[pos\_Radius] \ldots positron radius calculated from the decay positron momentum and magnetic
field at the point of decay.
\item[pos\_Theta] \ldots polar angle of the decay positron.
\item[pos\_Phi] \ldots azimuth angle of the decay positron.
\item[det\_time10] \ldots time difference between the positron and muon counters
(measured by the respective counters).
\item[gen\_time10] \ldots the time difference between the muon decay and the first muon hit
in the M-counter (i.e.\ {\tt muDecayTime - muM0Time}).
\item[det\_time10\_MINUS\_gen\_time10] \ldots {\tt det\_time10 - gen\_time10} in picoseconds.
\item[det\_time20] \ldots very similar to {\tt det\_time10}, however taking into
account ``counter phase shift'' defined by {\tt counterPhaseShifts}
variable. This gives the user a possibility to sum up backward and
forward histograms into one histogram (this of course make sense
only in the simulation, where there is ``no physics'' happening
in the sample, just the muon spin rotation).
\item[pileup\_eventID] \ldots eventID of the $\mu_2$, where $\mu_2$ stands for the muon,
which did not give signal in the M-counter, but whose
decay positron gave signal in the positron counter around the time
when a different muon ($\mu_1$) triggered the M-counter.
\item[pileup\_muDecayDetID] \ldots detector ID, in which $\mu_2$ stopped and decayed.
\item[pileup\_muDecayPosZ] \ldots $z$-coordinate of where the $\mu_2$ stopped and decayed.
\item[pileup\_muDecayPosR] \ldots radius of where the $\mu_2$ stopped and decayed.
\end{description}
Variables are usually set to -1000 if they can not be calculated (e.g.\ {\tt det\_posEdep} = -1000
if there was no hit in any positron counter).
\item{\bf musrTH2D \emph{histoName} \emph{histoTitle} \emph{nBins} \emph{min} \emph{max} \emph{nBins2} \emph{min2} \emph{max2} \emph{variable}} \\
Similar to \emph{musrTH1D}, but for a 2-D histogram.
\item{\bf humanDecayHistograms \emph{hist\_decay\_detID} \emph{hist\_decay\_detID\_pileup} \emph{id$_1$} \emph{name$_1$} \ldots \emph{id$_n$} \emph{name$_n$} } \\
This is a special kind of histogram, which converts two histograms
(\emph{hist\_decay\_detID} \emph{hist\_decay\_detID\_pileup})
into a human-friendly histograms, where detector ID on the $x$-axis is converted into a string label.
The \emph{id$_i$} is the detector id, and the \emph{name$_i$} is the corresponding label name.
If \emph{name$_i$ = name$_j$}, the corresponding bins of the original histograms will
be summed up together into the same bin.
The \emph{hist\_decay\_detID} and \emph{hist\_decay\_detID\_pileup} have to be defined before
(by the command {\tt musrTH1D}).
\item{\bf condition \emph{conditionID} \emph{conditionName}} \\
Definition of a condition, which is then used when filling histograms. The \emph{conditionID}
specifies the number of the condition, and must be between 0 and 30 (0 and 30 are also possible).
The \emph{conditionName} is one of the following:
\begin{description}
\item[alwaysTrue] \ldots true for every hit in the m-counter (there can be more than one M-counter hit per event).
\item[oncePerEvent] \ldots true once for every event (the first hit in M-counter, if any, is considered).
\item[muonDecayedInSample\_gen] \ldots true if muon stopped and decayed in the sample.
\item[muonTriggered\_gen] \ldots true if muon passed through the M-counter (irrespective of the deposited energy)
-- not a measurable variable.
\item[muonTriggered\_det] \ldots true if a good muon candidate was found in the M-counter (using coincidences, vetoes, ...).
Double hits within the pileup window are excluded.
\item[positronHit\_det] \ldots true if a good positron candidate was found in the positron counter.
Double hits within the data window are excluded.
\item[goodEvent\_det] \ldots true if {\tt muonTriggered\_det} and {\tt positronHit\_det}.
\item[goodEvent\_gen] \ldots true if muon passed through the M-counter, and the muon stopped anywhere
(i.e.\ did not leave the World volume of the simulation). No requirement
on the positron is implied, i.e.\ the positron may or may not be detected.
Not a measurable variable.
\item[goodEvent\_det\_AND\_goodEvent\_gen]
\item[pileupEventCandidate] \ldots M-counter hit and positron counter hit both come from two different events.
\item[pileupEvent] \ldots {\tt pileupEventCandidate} and {\tt goodEvent\_det}.
\item[goodEvent\_det\_AND\_muonDecayedInSample\_gen]
\item[goodEvent\_F\_det] \ldots {\tt goodEvent\_det}, where the positron was detected in the forward detectors
defined by the command {\tt counterGrouping}.
\item[goodEvent\_B\_det] \ldots like {\tt goodEvent\_F\_det} but for backward positron counters.
\item[goodEvent\_U\_det] \ldots like {\tt goodEvent\_F\_det} but for upper positron counters.
\item[goodEvent\_D\_det] \ldots like {\tt goodEvent\_F\_det} but for lower positron counters.
\item[goodEvent\_L\_det] \ldots like {\tt goodEvent\_F\_det} but for left positron counters.
\item[goodEvent\_R\_det] \ldots like {\tt goodEvent\_F\_det} but for right positron counters.
\item[goodEvent\_F\_det\_AND\_pileupEvent] \ldots {\tt goodEvent\_F\_det} and {\tt pileupEvent}.
\item[goodEvent\_B\_det\_AND\_pileupEvent] \ldots {\tt goodEvent\_B\_det} and {\tt pileupEvent}.
\item[goodEvent\_U\_det\_AND\_pileupEvent] \ldots {\tt goodEvent\_U\_det} and {\tt pileupEvent}.
\item[goodEvent\_D\_det\_AND\_pileupEvent] \ldots {\tt goodEvent\_D\_det} and {\tt pileupEvent}.
\item[goodEvent\_L\_det\_AND\_pileupEvent] \ldots {\tt goodEvent\_L\_det} and {\tt pileupEvent}.
\item[goodEvent\_R\_det\_AND\_pileupEvent] \ldots {\tt goodEvent\_R\_det} and {\tt pileupEvent}.
\end{description}
Additional conditions may be implemented on request.
\item{\bf draw \emph{histogramName} \emph{conditionID} } \\
Plot histogram (for a given condition) at the end of the analysis. Note that all histograms
are saved into the output file irrespective whether they are plotted or not.
\item{\bf counterPhaseShifts \emph{ID$_1$} \emph{$\phi_1$} \emph{ID$_2$} \emph{$\phi_2$} \ldots \emph{ID$_n$} \emph{$\phi_n$} }\\
Defines relative phase shifts of signal between different positron counters, which is used
for calculation variable {\tt det\_time20}. \emph{ID$_i$} is the ID number of the positron counter,
\emph{$\phi_i$} is its phase shift. This gives the user a possibility to sum up backward and
forward histograms into one histogram.
\item{\bf counterGrouping \emph{group} \emph{ID$_1$ ID$_2$ \ldots ID$_n$} } \\
This defines a group of detectors, where \emph{group} stands for ``B'' (backward),
``F'' (forward), ``U'' (up), ``D'' (down), ``L'' (left) and ``R'' (right) detectors.
This grouping is used in the definition of some conditions.
\item{\bf setSpecialAnticoincidenceTimeWindow \emph{detectorID} \emph{timeMin} \emph{timeMax} \emph{unit}} \\
This command sets a special anti-coincidence time window for a detector \emph{detectorID}.
Normally, the anti-coincidence time window is defined by {\tt VCOINCIDENCEW}, and is the same for all anti-coincidence
detectors. However, sometimes it might be interesting to set the anti-coincidence time window
differently for a specific detector (e.g.\ one might test an anti-coincidence of a veto detector with
the M-counter for the whole pile-up time window of $\sim$\,10\,$\mu s$.
Unlike in the case of {\tt VCOINCIDENCEW}, here the \emph{units} are not TDC bins, but
rather time in ``nanosecond'' or ``microsecond''.
\item{\bf fit \emph{histogramName} \emph{function} \emph{min} \emph{max} \emph{p$_1$} \ldots \emph{p$_n$}} \\
Fits the histogram by a given function, where \emph{min}, \emph{max} define the range of the fit
on the $x$-axis of the histogram, and \emph{p$_1$} \ldots \emph{p$_n$} are (typically, with some exceptions)
the initial values of the function parameters. The following functions are currently predefined:
\begin{description}
\item[pol0] $=p_0$ \ldots a constant (1 parameter) - typically used to fit background.
\item[simpleExpoPLUSconst] $=p_0 \exp(-x/2.19703)+p_1$
\item[rotFrameTime20] $= p_2 \cos(p_0 x+p_1)$
\item[funct1] $=p_3 \exp((p_4 - x)/2.19703) \cdot (1+p_2 \cos(p_0 x+p_1))$
\item[funct2] $=p_3 \exp((p_4 - x)/2.19703) \cdot (1+p_2 \cos(p_0 x+p_1)) + p_5$
% \item[funct3] the same as {\tt funct2}
\item[funct4] $=p_3 \exp((- x)/2.19703) \cdot (1+p_2 \cos(p_0 x+p_1)) + p_4$

\section{A real-life example: GPD instrument}
\label{sec:GPD}
The simulation of the General Purpose Decay-Channel Spectrometer (GPD)
instrument~\cite{GPD} installed at PSI has been exemplified
in the \musrSim\ manual~\cite{musrSim}.
Here we analyse the output of this simulation using \musrSimAna.
The run number of this simulation is 201, therefore the steering
file names are ``{\tt 201.mac}'' for \musrSim, and ``{\tt 201.v1190}'' for
\musrSimAna, respectively, and the output file name of \musrSim\ is saved as
``{\tt data/musr\_201.root}''.
The detector system is very simple with only six counters -- M-counter,
two backward positron counters and three forward positron counters.
The reader is strongly recommended to see the illustration of the GPD
geometry in the \musrSim\ manual~\cite{musrSim}.
8\,000\,000 of events were simulated
(i.e.\ 8\,000\,000 of muons were generated 100\,cm in front of
the GPD sample).
In only 949\,759 events (11.9\% out of the 8 million) there was a signal detected
in one or more counters. The remaining muons stopped somewhere (most
often in collimator, as we will see later), decayed, and the decay positron
(and any other particles created thereof) missed the counters.
This is illustrated in more details in Fig.~\ref{det_n},
%
\begin{figure}[tbp]\centering
\epsfig{file=pict/det_n_infititely_low_muon_rate.eps,width=0.8\linewidth,clip=}
\caption{Number of hits in all counters per event, assuming infinitely low incoming muon
rate. The same detector may be hit more than once (e.g.\ if both the muon and its decay
positron pass through the M-counter).}
\label{det_n}
\end{figure}
%
where number of detector hit per event, assuming infinitely low incoming muon
rate, is shown. This plot was created in Root by executing:\\[1em]
{\tt
root [0] TFile* ff=new TFile("data/musr\_201.root") \\
root [1] t1->Print() \\
root [2] t1->Print("det\_n","det\_n>0") \\
}\\[1em]
%
It has to be pointed out, that the ratio of muons passing through the opening
in collimators to the number of all generated muons strongly depends on the
beam properties -- beam profile, beam convergence, etc. Typically, if we have
too broad muon beam, we simulate
many ``useless'' events. However, the other extreme (simulating too narrow
beam) can lead to underestimating the time-independent background.
It took approximately 12 hours of the CPU (on PC bought in 2010, where 1 out
of 4 processor cores was running) to simulate these 8\,000\,000 events.
Assuming the 30\,000\,$\mu/$s trigger rate, this corresponds to 26 seconds
of real experimental running.
\subsection{Where the muons stop and decay}
\label{sect_muons}
The positions, or more precisely the components of the GPD instrument, where the muons
stop and decay, are shown in Fig.~\ref{humanDecayHistograms_1}:
%
\begin{figure}[tbp]\centering
\epsfig{file=pict/Plot201_1.eps,width=0.9\linewidth,%
%%bbllx=83pt,bblly=330pt,bburx=538pt,bbury=513pt,clip=}

\caption{This plot indicates, where the muons stopped and decayed.
The dashed histogram shows all generated muons. The full-line histograms show
where stopped the muons, for which either the muon itself or its secondary
particle ($e^+, \gamma$) triggered the M-counter: black histogram stands for
all such muons, corresponding to infinitely low incoming muon rate, while
the red histogram stands for the incoming muon rate of 30\,000\,$\mu/$s.
8\,000\,000 of events were simulated.}
\label{humanDecayHistograms_1}
\end{figure}
%
%Notes to Fig.~\ref{humanDecayHistograms_1}:
\begin{itemize}
\item Figure~\ref{humanDecayHistograms_1} was generated by Root macro file ``Plot201.C''.
\item The labels on the $x$-axis are defined in the file {\tt 201.v1190} by the
command \\
{\tt humanDecayHistograms \ldots}
\item The dashed-line histogram in Fig.~\ref{humanDecayHistograms_1}
shows where the muons stopped and decayed if no preselection
criteria are applied on the muons, i.e.\ if all generated muons are considered.
This is histogram ``{\tt humanDecayHistograms\_1}''.
\item The full-line histograms show
where stopped the muons, for which either the muon itself or its secondary
particle ($e^+, \gamma$) triggered the M-counter: black histogram stands for
all such muons, corresponding to infinitely low incoming muon rate, while
the red histogram represents the case for the 30\,000\,$\mu/$s incoming muon rate.
An energy deposit of at least 0.4\,MeV in the M-counter is required to fire the trigger.
The number of triggered events decreases with the incoming muon rate,
because some of the events are rejected due to the 10\,$\mu$s pileup gate.
The histogram name is in both cases ``{\tt humanDecayHistograms\_4}'',
where the black histogram was calculated using the setup file ``{\tt 201a.v1190}''
with the keyword {\tt INFINITELYLOWMUONRATE}, while the red histogram
was calculated using the setup file ``{\tt 201.v1190}''
with {\tt MUONRATEFACTOR=0.0965819}.
\item The $\pm 10\,\mu$s pile-up gate at the incoming muon rate of 30\,000$\,\mu/$s
rejects approx.\ 45\% of the triggered events. This number can be calulated
in Root as the ratio of the ``{\tt Integral}'' of the red and black histograms
in Fig.~\ref{humanDecayHistograms_1}:\\[1em]
{\tt \small
root [0] TFile* file1 = new TFile("data/his\_201\_201a.v1190.root") \\
root [1] humanDecayHistograms\_4->Integral() \\
root [0] TFile* file2 = new TFile("data/his\_201\_201.v1190.root") \\
root [1] humanDecayHistograms\_4->Integral() \\
}
\item The muon sample fraction (ratio of muons stopped in the sample over all muons that fired
the trigger) for the triggered events (full-line histograms)
is 65\%, and it is practically the same
for both infinitely low and 30\,000\,$\mu/$s incoming rate.
This number can be obtained in Root by dividing the first column of histogram
{\tt humanDecayHistograms\_4} by the sum of all entries in this histogram:\\[1em]
{\tt \small
root [0] TFile* file = new TFile("data/his\_201\_201.v1190.root") \\
root [1] (humanDecayHistograms\_4->GetBinContent(1))/(humanDecayHistograms\_4->Integral()) \\
}
\item The largest fraction of generated muons (dashed-line histogram) stopped in collimators.
Only a small fraction of them caused a hit in the M-counter (full-line histograms).
\item Despite the high initial muon momentum of $100 \pm 3\,$GeV/c, muons are
significantly scattered in the last 50\,cm region of air. This can be
clearly seen if the magnetic field is off and a point-like muon beam
is used (which can be done by modifying the {\tt 201.mac} file)
-- only 77\% of the muons stop in the sample cell or in the sample, while the
remaining 23\% of the mouns are scattered so much in the air, that they
end up in collimators or elsewhere (not shown here).
\item ``World'' in the histogram label means that the muon decayed in the beampipe vacuum
or somewhere else in the air (on the fly).
\item ``Escaped'' means that the muon left the simulated instrument (more precisely the
``world'' volume) prior its decay.
\end{itemize}
Figure~\ref{humanDecayHistograms_9} shows the ``pile-up events''.
%
\begin{figure}[htbp]\centering
\epsfig{file=pict/Plot201_2_new.eps,width=0.9\linewidth,%
%%bbllx=83pt,bblly=330pt,bburx=538pt,bbury=513pt,clip=}
clip=}
\caption{Pile-up events, i.e.\ the events in which one muon ($\mu_1$) fired the
trigger, while the hit in a positron counter is due to a decay positron from
a different muon ($\mu_2$). Pile-up events look like a good events, and contribute
to the time-independent background.}
\label{humanDecayHistograms_9}
\end{figure}
%
These are events, in which one muon ($\mu_1$) is triggered by the m-counter,
while a positron from a different muon ($\mu_2$) was detected by
a positron counter\footnote{In fact, the trigger may also be triggered by
the decay positron of $\mu_1$ and/or a positron counter may detect
directly $\mu_2$, not its decay positron. Such cases are rare, but they
are implicitly included in the simulation.}.
In addition to this requirement, the decay positron of $\mu_1$ must
escape undetected (e.g.\ it must miss positron counters) and $\mu_2$ must not trigger the m-counter
-- otherwise the event would be rejected.
Pile-up events are the source of the time independent background.
Usually $\mu_1$ is a good-looking muon that stops in the sample or in the sample cell
(red histogram in Fig.~\ref{humanDecayHistograms_9}), while $\mu_2$ stops and decays at different places,
mainly in the collimators (green histogram in Fig.~\ref{humanDecayHistograms_9}).
A nice visualisation of where the background-contributing muons $\mu_2$ stop and decay
is presented in Fig.~\ref{Pileup_muon_decay_map} (histogram ``{\tt hMuDecayMappileup\_9}'').
%
\begin{figure}[htbp]\centering

\caption{Positions of where the $\mu_2$ stop and decay.}
\label{Pileup_muon_decay_map}
\end{figure}
%
In this two dimensional histogram, different components of the GPD instrument,
like the lead collimator, the copper collimator and the sample cell, can be recognised.
The lead collimator is located at the $z$-position between -115\,mm and -85\,mm.
Due to the high initial muon momentum of $\sim 100\,$MeV/c,
the maximum of muons in Fig.~\ref{Pileup_muon_decay_map} stop quite deep in the
lead collimator, at around $z=-103$\,mm. This might be a little bit surprising to the
\musr\ scientists who are used to work with the surface muons with momentum of 28\,MeV/c.

%
shows the $\mu$SR spectra for the same run,
i.e.\ for the transverse field of 300\,gauss, integrated over the three forward positron
counters (left histogram called {\tt hdet\_time10\_10})
and over the two backward positron counters (right histogram called {\tt hdet\_time10\_11}).
Zero on the time axis corresponds to $t_0$, i.e.\ time of the m-counter hit.
One can see a prompt peak at $t_0$, time independent background at negative times
and an oscillating signal at positive times.
The following function has been fitted to the oscillating part of the signal:

\begin{equation}
f=p_3 \cdot e^{-t/2.19703} \cdot (1+p_2 \cdot \cos(t \cdot p_0+p_1))+p_4
\label{eq_simple}
\end{equation}
The fits were restricted to the time interval of $(t_0+0.05 \mu\rm{s},t_0+9.95\mu\rm{s})$,
and the parameter $p_0$ was fixed (e.g. not fitted).
The fitted amplitude of asymmetry are $p_2 = 0.307 \pm 0.009$ and
$p_2 = 0.290 \pm 0.009$ for the forward and backward counters respectively.
Parts of the spectra from Fig.~\ref{hdet_time10_10} are shown
in detail in Fig.~\ref{hdet_time10_10_detail}.

Fig.~\ref{hdet_time10_10}. The left plot shows the signal in the forward counters around $t_0$,

\label{hdet_time10_10_detail}
\end{figure}
%
The left plot in Fig.~\ref{hdet_time10_10_detail} shows the signal
in the forward counters around $t_0$, the right plot shows the
(time-independent background) signal at negative times in the backward counters.
An important characteristic of a \musr\ instrument is the time-independent
background. It is usually expressed as
%
\begin{equation}
{\rm Bgr} = p_{-} / p_3 ~~~,
\label{eq_background}
\end{equation}
%
where $p_{-}$ is the fit to the time-independent background, i.e.\ signal at negative times,
and $p_3$ is the parameter from eq.(\ref{eq_simple}), which specifies what the
size of the signal would be at $t_0$ in the absence of oscillations.
In the case of backward counters ${\rm Bgr}_{\rm backw} = 14.47/262 = 5.5\,\%$,
in the case of forward counters ${\rm Bgr}_{\rm forw} = 6.88/267.9 = 2.6\,\%$.
Note that the histogram on right hand side of Fig.~\ref{hdet_time10_10_detail}
is labelled ``{\tt hdet\_time10\_Bgr\_11}'', not ``{\tt hdet\_time10\_11}''.
In fact, the two histograms are identical, as one can see in the setup file
{\tt 201.v1190}. The only difference is in the fitting -- the same data stored in
both histograms are fitted by different functions in different time ranges.

\subsection{The $\mu$SR signal from individual counters}
%
Figure~\ref{F11} shows the observed signal in the
forward counter\ No.~11 (FW11).
%
\begin{figure}[htbp]\centering

\caption{\musr\ signal in the forward positron counter\ No.~11 (run 201, TF$=300\,$gauss).
The left plot shows the (rebinned) signal in the counter,
the right plot shows the detail of the \emph{prompt peak}, i.e.\ the region
around $t_0$ in the same counter (black line),
compared with the prompt peak in the backward positron counter\ No.~1 (magenta line).}
\label{F11}
\end{figure}
%
Originally, the histogram F11 was defined with the bin width of 100\,ps.
The number of bins was 50995, covering the time interval of approx.\ (-0.2\,$\mu$s, 4.9\,$\mu$s).
In the left hand side plot, however, the histogram was rebinned
(200 bins were summed up into 1 bin).
The right hand side plot shows the detail of the \emph{prompt peak}, i.e.\ the region
around $t_0$, of one forward and one backward positron counters, prior to the rebinning.

\subsection{Conclusion of the GPD analysis example}
%
The purpose of the example analysis of the GPD simulation was to illustrate
the potential of \musrSim\ and \musrSimAna\ programs to investigate features
like time-independent background, sample muon fraction, prompt peak, \ldots
This information can be used in design and optimisation of \musr\ instruments.
