\subsection{AMOR Reflectometer Settings}
|
||||
This is yet another module for calculating the settings for the AMOR
|
||||
spectrometer. This version is of 2005 and implements the new calculation
|
||||
scheme as devised by the Jochen where the base line and height zero point
|
||||
is the beam height at the chop, chop, chopper.
|
||||
|
||||
Again a lot of parameters have to be maintained. For each optical bench
|
||||
component an active flag, a fixed offset for correcting the scale reading to
|
||||
the actual position and an offset regarding the zero point of the scale need
|
||||
to be kept. And of course the value as read. This is offloaded into a
|
||||
separate module, amorcomp. Beamline components to be controlled are:
|
||||
\begin{description}
|
||||
\item[DS] The slit at the monochromator bunker
|
||||
\item[M] The monochromator
|
||||
\item[Dx] various slits
|
||||
\item[A] the analyzer
|
||||
\item[D] the detector.
|
||||
\end{description}
|
||||
|
||||
A master module encloses all those beamline components and performs the
|
||||
actual calculation. The calculation is controlled through three virtual
|
||||
motors: m2t (monochromator 2 theta), s2t (sample 2 theta) and ath, the
|
||||
analyzer angle. For the formula used for the exact calculation, see the
|
||||
paper from the Jochen.
|
||||
|
||||
|
||||
The amorcomp module provides the following interface:

The amorset module implements the container for all the data and the actual
|
||||
calculation. Most of the interesting stuff is in the functions relating to
|
||||
the interpreter interface and the drivable interface. Again the virtual
|
||||
motors only set values in the amorset data structure and amorset then takes
|
||||
control off the driving operation.
