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
- https://docs.google.com/spreadsheets/d/1mt39fCuIW3Pr8TO7fzhtFjmMFt4Op30jMm5wMQke6Xo/edit?usp=sharing
Issues
- 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
- 12X energy shifting
- Dispersion in the arc is measured as 0.4 MeV/mm
- Dispersion in the HRS is 6.2 mm/MeV
- Dithering does a 0.5 mm p2p fluctuation in 12 X -> 1.25 mm shift in the HRS Quartz
- Normal running without FFB does 1 mm p2p fluctuations (over hour time scale) -> 2.5 mm shift in the HRS quartz
- 5477.0 has a significant problem in JAPAN
- Long vs. short bursts will require JAPAN rNd from Paul, etc.
- The AT combos of interest are Ldd avg Rdd (for vertical transverse), Indd avg Outdd (most important for horizontal transverse), and dd's therein
BCMs
- Run 5474 is a current ramp for calibrating BCM Cav 4CQ, AT Rs, and SAM 7
Target/Energy Tolerances

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")
