areaDetector: EPICS software for area detectors</h1>
<p>
Module Owner: Mark Rivers: University of Chicago</p>
<p>
This page is the home of <b>areaDetector</b>, an application for controlling area
(2-D) detectors, including CCDs, pixel array detectors, and online imaging plates.
</p>
<p>
<b>NOTE:</b> This module replaces the <a href="http://cars.uchicago.edu/software/epics/ccd.html">
ccd</a> and <a href="http://cars.uchicago.edu/software/epics/epilatusROI.html">pilatusROI</a>
modules. These older modules will no longer be supported, and users are encouraged
to convert to this new areaDetector software.</p>
<p>
Devices supported in <b>areaDetector</b> include:</p>
<p>
From <a href="http://www.dectris.com">Dectris</a>
</p>
<ul>
<li>The <a href="http://www.dectris.com/sites/pilatus100k.html">Pilatus</a> pixel-array
detector.</li>
</ul>
<p>
From <a href="http://www.prosilica.com">Prosilica</a>
</p>
<ul>
<li>High-speed, high-resolution CCD cameras. These use GigE and Firewire interfaces.</li>
</ul>
<p>
From <a href="http://www.adsc-xray.com/">ADSC</a>
</p>
<ul>
<li>Large CCD detectors for x-ray diffraction. This support is from Lewis Muir of
IMCA-CAT at the APS. </li>
</ul>
<p>
From <a href="http://www.mar-usa.com/">MAR</a></p>
<ul>
<li>MarCCD detectors</li>
<li>MAR-345 online image plate reader (coming soon)</li>
</ul>
<p>
From <a href="http://www.roperscientific.com/">Roper</a></p>
<ul>
<li>All CCD detectors supported by the WinView and WinSpec programs. This includes
all <a href="http://www.princetoninstruments.com/">Princeton Instruments</a> detectors,
as well as most <a href="http://www.photomet.com/">Photometrics</a> detectors. </li>
</ul>
<p>
From <a href="http://www.bruker-axs.de/">Bruker</a></p>
<ul>
<li>The SMART CCD camera line with Photometrics cameras. This requires the PCI interface
card, replacing the old ISA bus card, and requires controlling the detector with
WinView, not the SMART software.</li>
</ul>
<p>
From <a href="http://www.ptgrey.com/products/flea2/index.asp">Point Grey Research</a></p>
<ul>
<li>The Flea2 line of Firewire cameras. It also supports other brands of Firewire
cameras. It currently works under Linux only. This support was written by Ulrik
Pedersen from Diamond Light Source and is distributed separately from the areaDetector
module.</li>
</ul>

<h2>
Where to find it</h2>
<p>
The areaDetector module is in the EPICS Applications SVN repository on <a href="http://epics.svn.sourceforge.net/viewvc/epics/applications/trunk/areaDetector/">
SourceForge.</a> Persons wishing to collaborate on this project can contact Mark
Rivers to get write access to this application there.
</p>
<p>
You can download the software from the links in the table below. The software is
available both in source code form, and in pre-built form so that it can be used
without an EPICS build system. The pre-built form includes binaries for linux-x86,
win32-x86, solaris-sparc and some vxWorks archtectures.</p>

<h2>
Installation and Building</h2>
<h3>
Source code version</h3>
<p>
After obtaining a copy of the distribution, it must be installed and built for use
at your site. These steps only need to be performed once for the site (unless versions
of the module running under different releases of EPICS and/or the other required
modules are needed).</p>
<ol>
<li>Create an installation directory for the module, usually this will end with<br />
<br />
<tt>.../support/</tt>
<br />
</li>
<li>Place the distribution file in this directory. Then issue the commands (Unix style)
<pre>tar xvzf areaDetectorRX-Y.tgz
</pre>
where X-Y is the release.</li>
<li>This creates a &lt;top&gt; application.<br />
<pre>.../support/areaDetectorRX-Y
</pre>
</li>
<li>Edit the <tt>configure/RELEASE</tt> file and set the paths to your installation
of EPICS base and to your versions of supporting modules.</li>
<li>Run <tt>gnumake</tt> in the top level directory and check for any compilation
errors.</li>
</ol>
<h3>
Prebuilt version</h3>
<ol>
<li>Create an installation directory for the module.</li>
<li>Place the distribution file in this directory. Then issue the commands (Unix style)
<pre>tar xvzf areaDetectorPrebuiltRX-Y.tgz</pre>
</li>
<li>In the iocBoot directory make a copy of the example ioxXXX directory for the detector
you are using and give it a new local name. By doing this you will be able to update
to later versions of areaDetector without overwriting modifications you make in
the iocXXX directory.</li>
<li>In the new iocXXX directory you just created edit st.cmd to change the PV prefix
$(P) to one that is unique to your site. PV prefixes must be unique on the subnet,
and if you use the default prefix there could be a conflict with other detectors
of the same type. </li>
<li>In the same iocXXX directory edit the file envPaths to point to the locations
of all of the support modules on your system. Normally this is handled by the EPICS
build system, but when using the prebuilt version this must be manually edited.
Do not worry about the path to EPICS_BASE, it is not required.</li>
</ol>
