March 18-24

Tuesday, March 19

• TAC runs continued until about noon today, after which we went back to our empty target
• Sasha's plot showing PS acceptance vs tagger energy: https://logbooks.jlab.org/entry/3669644
• Fill target tomorrow, and in the future we will continue the plan of going to empty target on Sunday evenings, and using the RF recovery time on Tuesdays to refill the target
• Tomorrow we will adjust the channels in FCAL where the gains were distinguished by Ilya to be suspicious and quickly check the signals

Wednesday, March 20

• The target was filled this morning: https://logbooks.jlab.org/entry/3670092
• We decided to not include the FCAL+FCAL compton scattering plots in the monitoring because at energies above 3 GeV (our trigger threshold) there is no acceptance outside the inner layer.
• Beam stopped at about 7 am this morning for RF recovery, and we are still waiting to get it back.

Friday, March 22

• Ilya pointed out that some runs included in the production runs list (specifically 61540-61545) don't have trigger bits set properly. We realized that these runs are when Sasha and Ben were doing trigger tests, and should be marked as junk. Not a big deal, this just shows that we should take more care in adding comments to the runs so we don't waste time.
• Sasha will update geometry tonight.
