- SHMS 2Y- scalers restored during the middle of SHMS run 17336 - those scalers were missing for all runs before this
October 9, 2022
- SHMS PID thresholds set - just before SHMS run 17318:
- NGC: -12.7 mV
- PRLO: -35.4 mV
- PRHI: -44.2 mV
October 6, 2022
- SHMS PRLO and PRHI thresholds increased to -45.4 and -50.9 mV to get rid of huge "no beam rate."
- These thresholds were used for most of SHMS paddle study - affects runs starting with 17261
- Mark updated the trigger mapping for SHMS DAQ (see elog https://logbooks.jlab.org/entry/4051681)
- Would only have impacted data taken with elclean trigger - we had not taken any to this point, so not an issue
