<h1>Logging in to Unix Workstations</h1>
|
|
You are required to have a user name and a password in order to log on to one
|
|
of the instrument workstations. There are several possible cases:
|
|
<ul>
|
|
<li>You have a PSI network account in the LNS group: use your very own name
|
|
and password.
|
|
<li> You are a guest: use account lnsg with password Saphir. You will be
|
|
asked for your name, type it in and you will be automatically directed to
|
|
a directory of your own.
|
|
</ul>

<h1>Running the SICS Instrument Control System </h1>
|
|
SICS is a client server system. This means there is a server doing the hard
|
|
work and client programs with which you interact. Thus in order to run SICS
|
|
two programs are necessary.
|
|
<DL>
|
|
<DT>A SICS server
|
|
<DD> You need not worry about that one. The system will keep it alive. But
|
|
see below.
|
|
<DT>A SICS Client.
|
|
<DD> These are the programs you interact with. There are different ones for
|
|
different instruments. The next section shows how to start them.
|
|
</DL>
|
|
</p>
|
|
<p>
|
|
<b> All SICS Clients</b> are inactive after having been started up. In order
|
|
to be useful each client needs to be connected to a SICS instrument control
|
|
server. This is achieved through the menu entries in the Connect menu. For
|
|
usage instructions for the clients, consult the help menu of the client in
|
|
question.
|
|
</p>
|
|
<p>
|
|
<h2>General SICS Clients</h2>
|
|
This section describes SICS clients common to all instruments. There are
|
|
two of those:
|
|
</p>
|
|
<p>
|
|
The <b> SICS Command Line Client</b> allows to control the instrument. It
|
|
can be started by typing: <b> sics &</b>. SICS supports a hierarchical
|
|
system of user privileges. After connecting to a SICS server a client may
|
|
look at everything but cannot change anything or even run an experiment. In
|
|
order to do this, you need to authorize yourself at the SICS server. This
|
|
can be done with the User Parameters/Set Rights dialog. A valid
|
|
username/password combination is: lnsuser/98lns2. When starting a new
|
|
experiment do not forget to set experiment information with the User
|
|
Parameter/New Experiment menu. Otherwise we might find it impossible to
|
|
recover your files when you ask for them in 10 years time.
|
|
</p>
|
|
<p>
|
|
The second general pupose SICS client is the <b>variable watcher</b>. It plots the
|
|
value of any SICS variable over time. It can be started by typing:
|
|
<b>varwatch &</b> at the command prompt. This client must be connected and
|
|
configured through the Plot/Configure menu before becoming useful.
|
|
</p>
|

|
|
<h2>DMC Programs</h2>
|
|
The powder diffractometer DMC has two special programs:
|
|
</p>
|
|
<p>
|
|
A <b>status display</b>, which shows the current powder diagram together with some
|
|
auxiliary information. It can be started by typing <b>powderstatus &</b> at
|
|
the command prompt.
|
|
</p>
|
|
<p>
|
|
Another program is used for <b>summing and subtracting powder diffraction
|
|
diagrams</b> to a result diagram and to write the result in ASCII. This program
|
|
can be started by typing <b>powderplus &</b> at the command prompt.
|
|
</p>
|
|
<p>
|
|
<h2>TOPSI Programs</h2>
|
|
TOPSI has only a <b>status display</b>, which shows the current scan together with
|
|
some auxiliary information. It can be started by typing <b>topsistatus &</b> at
|
|
the command prompt.
|
|
</p>
|
|
<p>
|
|
<h2>SANS Programs</h2>
|
|
SANS has only a <b>status display</b>, which shows the current detector counts and
|
|
some auxiliary information. It can be started by typing <b>sansstatus &</b> at
|
|
the command prompt.
|
|
</p>
|
|
<p>
|
|
<h1>SICS Manager Commands</h1>
|
|
These commands install and start SICS services. They must be
|
|
executed from the instrument account on the instrument computer. When using
|
|
the shell script sicsinstall, you need to be in the home
|
|
directory of the instrument account. The commands are:
|
|
<DL>
|
|
<DT>startsics
|
|
<DD> starts all SICS servers properly. Usually this must only be used after
|
|
a reboot of the instrument computer.
|
|
<DT>sicsinstall exe
|
|
<DD>installs new SICS executable files into the appropriate directories.
|
|
<DT>sicsinstall instrument
|
|
<DD>installs all files necessary for running the instrument. instrument must
|
|
be one of: dmc, topsi or sans.
