Device Configuration Details

This section is mostly for Beamline Support in setting up devices. Bluesky/EPICS relies on specific device configurations in some cases, so one may refer here in the case of strange behavior.

Calibrating the Xspress3

The Xpress3 ships with calibration software. With the IOC off, run remote.py in /usr/lib64/python2.7/site-packages/xspress3-autocalib/remote.py.

After some time a web page should appear with options to either collect a spectrum or perform autocalibration. Once you have confirmed the xspress3 is collecting data from a copper standard, start the calibration procedure. This process should center the copper peak at 8045 eV.
