March 25-31

Monday, March 25

• We've had issues with the CCAL HV crate. The problem is with the control module in the crate directly. We replaced the crate, but now the voltages can't be seen in the EPICS and we are running almost blind with regards to CCAL voltages (can still check scalers as a basic check though).

• Sasha's plot of tagger accidentals using PS trigger: https://logbooks.jlab.org/entry/3672169
• We decided against increasing the beam current because the statistical improvement is not enough to justify any potential risks. Also, increasing current would require us to turn off the CDC.
• We plan to run with lower current in the last week of the running period to study systematics, but we will need to figure out what current and how long to run before that time.

Sunday, March 31

• We will go to empty target tomorrow morning during beam studies.
