Daily Meeting BlueJeans

Production Run List - Slug 105 - IHWP IN - Flip-RIGHT - Production

  • Good - Run 5576 - Ca48 150uA - About 1 minirun worth of OK beam. A run all by itself in slug 105. cuts from 220-240k to remove an excursion

Production Run List - Slug 106 - IHWP OUT - Flip-RIGHT - Production

  • Good - Run 5581 - Needed a cut for a beam moving at the beginning, and for clipping towards the end
  • Good - Run 5582
  • Good - Run 5583
  • Good - Run 5613 - First run back from Compton tuning, with BMW testing in it - Cut beam excursions at 0-30k, 80-220k - Large Aq RMS, due to Injector problems. Fixed later by Ops
  • Good - Run 5616 - Good
  • Good - Run 5619 - Short, bad Aq Feedback, OK
  • Good - Run 5620 - Short, bad Aq Feedback, OK

Non-Production Runs and Bad Runs

  • Short - Run 5614 - completely trippy beam with some 125 uA data included at the end. 1/4 of a normal minirun size, and the Aq is at 11ppm which is slightly greater than the 1 sigma limit, BAD
  • Short - Run 5617 - bad Aq

Pedestal/Calibrations Updates

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

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")
