BLD Generation
This section is included for background knowledge on how to configure LCLS2 BLD from an accelerator IOC.
Taking the GMD (PV base = EM1K0:GMD:HPS) as an example:
Configuration of SuperConducting Soft x-ray BLD:
(ps-4.5.24) bash-4.2$ caget EM1K0:GMD:HPS:SCSBR:ENB
EM1K0:GMD:HPS:SCSBR:ENB Enable
(ps-4.5.24) bash-4.2$ caget EM1K0:GMD:HPS:SCSBR:MULT_ADDR
EM1K0:GMD:HPS:SCSBR:MULT_ADDR 239.255.25.2
(ps-4.5.24) bash-4.2$ caget EM1K0:GMD:HPS:SCSBR:MULT_PORT
EM1K0:GMD:HPS:SCSBR:MULT_PORT 10148
For SuperConducting Hard x-ray BLD (LCLS2-HE) replace SCS with SCH.
The supporting PVs are described here (BLD PVs). More detailed IOC setup instructions are found in the README file of the bsaDriver /afs/slac/g/cd/swe/git/repos/package/epics/modules/bsaDriver.git.
BLD Reception
The LCLS2 DAQ release has tools analogous to the LCLS1 DAQ for debugging BLD reception issues. The application in the LCLS2 DAQ release can be run as
