Pedestal/Calibrations Updates

• Devi has pedestals for SAMs and Main detectors - a new SAM pedestal run will need to be made with Devi's update
• We only have a Detector calibration - Caryn
• We need to take pedestals for BPMs - Amali

Issues

Marked DONE later once completed

• beam mod analyzer + plotter documentation - DONE
  • get bmod analysis results into a panguin or prompt plot
  • get bmod analysis slopes into a online japan corrector for live regressed results
• dither correction / combiner map - DONE
• replace aggregator folder with develop - DONT DO
• make sure prex/crex data don't become mixed - fix grand agg plots - DONE
• fix burst definition as events passing cuts instead of fixed time intervals - DONE
  • respin previous data - DONE
• make the combiner and mulc maps up to date - DONE
  • fix missing channels and add new ones to aggregator - DONE

BCMs

• We want to use BCM an US as our normalizer and feedback BCM - DONE
• We need to check with Hall C and turn their feedback back on when they want it (still not 100% checked out that the EPICs print for Hall C is independent) - DONE
• We need an Unser curent ramp to calibrate these at 150 uA - Caryn - DONE

Target/Energy Tolerances

• How much of a excursion is dangerous for Ca48 frame issues? - Bob and Silviu say +-0.5 mm is still a good cut metric - DONE
• How well centered are we on the middle of the 9.4 mm Ca48 frame? Beam Centering and Q^2 Log entry - DONE
• Beam Energy Fluctuation tolerances with Excited States in HRS?? - FFB fixes this! Arc 1 vs 2 energy measurements and locks are OK - DONE

Commissioning needs

• Compton Chicane - DONE
• BMW commissioning - DONE
• Spot size on the target minimization - DONE
• FFB commissioning - Today day shift - DONE

Other Status Updates

TS Tagger

I go the TS tagger to work and put panguin diagnostic plots in on Dec 9th: https://logbooks.jlab.org/entry/3750266

BMOD Ana

note regarding beammod analysis:

Running the BeamMod analysis for a single run.

From ~/PREX/prompt/bmodAna/ create a new beammod root file from the already prompted run (####) using command root -l -b -q bmodAna.C'(####,"max_input.list")'

then, to plot all combinations of alphas, deltas,and alpha/delta use the common root -l -b -q plotAD.C'("path/to/rootfile/created/by/the/previous/command.root")

Counting Mode Downstream Detectors

• Devi has changed DS detectors to counting mode at 5420
