Production Run List - Slug 106 (b) - Production

• Good - Run 5636 - Ca48 150uA - very messy beam, otherwise OK small amount of data
• The magnet setting splits this slug to 107

Pedestal/Calibrations Updates

Issues

• Adjustment in LHRS dipole current messed up the detector alignment - gets its own separate slug 107 - WAC diagnostic on widths here: https://logbooks.jlab.org/entry/3761778
• FFB was saturating all night, killing lots of our data with BPM cuts - this was due to improper limits on auto-gaining BPMs set by OPS - this made some strange noise upon FFB restoration after BMW cycles: https://logbooks.jlab.org/entry/3761789
• Run 5646 had a LQ1 trip, cutting out events 200k and onward in that run only

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'(####,"some_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

• Removed from cuts and correlator channel maps for safety
