Production Run List - Slug 104 - pre-Production

  • Good - Run 5477 - Ca48 150uA - Cut out the first 45k events due to strong beam instability
  • Good - Run 5478 -

Non-Production Runs and Bad Runs

Pedestal/Calibrations Updates


  • Slug 104 has FFB turn on mid way through the slug - this makes the optics/energy in the HRS more comfortable and stable
  • SAM 7 is updated and ATs are moved at the end of slug 103 and ATs are moved at the end of slug 104, so these are bifurcations
  • Fixed the prompt summary to report correct number of patterns: https://logbooks.jlab.org/entry/3753878


  • Run 5474 is a current ramp for calibrating BCM Cav 4CQ, AT Rs, and SAM 7

Other Status Updates


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")
