Non-Production Runs and Bad Runs

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

  • beam mod analyzer + plotter documentation
    • 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
  • replace aggregator folder with develop
  • make sure prex/crex data don't become mixed - fix grand agg plots
  • fix burst definition as events passing cuts instead of fixed time intervals
    • respin previous data
  • make the combiner and mulc maps up to date
    • fix missing channels and add new ones to aggregator


BCMs

  • We want to use BCM an US as our normalizer and feedback BCM
  • 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)
  • We need an Unser curent ramp to calibrate these at 150 uA - Caryn

Target/Energy Tolerances

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

Commissioning needs

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

Other Status Updates

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
