<P>

|
Data files at AMOR are stored in NeXus format, based on HDF-5. This is
|
|
a portable binary format. For more information see the <a
|
|
href="http://lns00.psi.ch/NeXus/"> NeXus WWW-pages</a>. Data storage
|
|
happens normally without user intervention during scans or after a
|
|
count command has finished. A couple of things are noteworthy,
|
|
however:
|
|
<ul>
|
|
<li>Data Storage in TOF-mode may take several minutes due to the
|
|
amount of data to transfer. In this time the SICS server will be quite
|
|
unresponsive.
|
|
<li>Data file writing can be interrupted. This is a unique feature at
|
|
AMOR. As a consequence, a data file is NOT automaticaly created when
|
|
a measurement has been interrupted.
|
|
<li>Data file writing can be forced by typing: <em>storeamor</em>.
|
|
<li>Data files can be found in directories: /home/AMOR/data/YYYY on
|
|
the instrument computer or (after a litlle delay) at
|
|
/data/lnslib/data/AMOR/YYYY . The YYYY is a placeholder for the year
|
|
of data collection.
|
|
<li>The last data file written can be overwritten with command:
|
|
<em>killfile</em>. Managers privilege is required for this command.
|
|
</ul>
|
|
</P>
|
|

|
|
In order to have complete information in the data files a couple of
|
|
SICS variables have to be set manually. A SICS variable's value can be
|
|
interrogated by typing the name of the variable, and set by typing the
|
|
name of the variable followed by the new value. The following
|
|
variables are relevant:
|
|
<dl>
|
|
<dt>user
|
|
<dd>User name
|
|
<dt>email
|
|
<dd>User e-mail address.
|
|
<dt>fax
|
|
<dd>User fax number
|
|
<dt>phone
|
|
<dd>User phone number
|
|
<dt>adress
|
|
<dd>User address.
|
|
<dt>sample
|
|
<dd>Sample name.
|
|
<dt>title
