Overview

Multi-gain-range detectors are more complex than previous LCLS detectors and calibration constants are not calculated by calibman, but instead using scripts described here.

...

The DAQ and detector groups provide scripts to generated generate special xtc files in various gain ranges and (for epixepix10ka) charge-injection.

Epix10ka

Both dark/offset calibrations do not have to be done for all gain ranges.  The calibration system will insert dummy constants for the gain ranges that are not included.

...

  • must be done after either the offsets or pedestals have changed
  • can be used when creating a new experiment.
  • it requires an existing expt/run-number so it can see the panel-id's and copy the appropriate constants into the experiment calib-dir

Jungfrau

The detector group must provide all gain/offset data for jungfrau.

 Commonly used commands:

Code Block
jungfrau_ndarr_dark_proc -h
jungfrau_deploy_constants -h

jungfrau_gain_constants -h  (done more rarely by psana/detector experts)

The "jungfrau_gain_constants" script can be used to setup the calib-dir for a new experiment.

Example of deployment geometry files:

geometry_deploy_constants -e cxic00121 -r 75 -d CxiDs1.0:Jungfrau.0 -D
