Jet Tracking Shared Memory Application
Information from detectors controlled by the LCLS Daq is output to EPICS PVs through a psana shared memory application.
SC1 Experiments
In the standard CXI configuration for the 1 um SC1 chamber,
the following will start a psana shared memory application for the DSC CSPAD
detector and output information to epics PVs with the base
CXI:SC1:DIFFRACT.
Normally this application will be run for the primary CXI experiment on
daq-cxi-mon01 with:
/reg/g/pcds/pyps/apps/hutch-python/cxi/cxi/jet_tracking/psana2epics.sh --alias='DscCsPad' --pvbase='CXI:SC1:DIFFRACT'
To check the processing event rate with the Daq running, use the
caEventRate on any CXI control room machine:
caEventRate CXI:SC1:DIFFRACT:TOTAL_ADU.VAL
SC2 Experiments
For the 100 nm SC2 chamber, the primary Daq and daq-cxi-mon01 will
generally be used, and the shared memory application can be started as follows:
/reg/g/pcds/pyps/apps/hutch-python/cxi/cxi/jet_tracking/psana2epics.sh --alias='DsaCsPad' --pvbase='CXI:SC2:DIFFRACT'
SC3 Experiments
For experiments in the SC3 Serial Sample Chamber (a.k.a., SSC chamber), the
secondary Daq will generally be used, and the shared memory application will
run on daq-cxi-mon06.
/reg/g/pcds/pyps/apps/hutch-python/cxi/cxi/jet_tracking/psana2epics.sh --alias='DsdCsPad' --pvbase='CXI:SC3:DIFFRACT'
