Agenda

Present:
Juliette, Paul, Nickie, Caryn, Rakitha, Bob, Kent, Tyler, Dustin, Guido

Pedestal Analysis by Caryn : elog-3010

Minutes

  • Dustin will start installing Lumi in the hall starting Friday 13th
  • Pedestal analysis update by Caryn
    • Pedestal analysis needs more sanity checks - Kent, Caryn, Ciprian
    • Fix issues with the PAN
  • Update from Thia - KK
    • Cryo-cooling for solid target with 20-30 uA is not going to be accessible in December run
    • 5 uA is the limit on the solid target with no Cryo-target
    • Therefore we need to Cryo-cooling to reach higher rates to check noise levels on lumis
    • Another possibility to try this out during GeMp in Spring-2016
  • Earliest beam time would be December 6th
  • Therefore goal for December run would be to check out DAQ, commission the beam and test BPM and BCM during December 6th
    • Cryo-cooling would not be accessible in December run
  • Preparations
    • Pedestal studies
    • Cabling for halo, beam monitor, lumi
  • Update from Thia about the PREX support meeting (Engineering and target groups) - KK
    • Which scattering chamber or target design to use for PREX/CREX needs to be determined
    • Cryo-cooling issue with two tall narrow chambers
      • Target group think this is feasible to have separate cryo lines in each scattering chamber
    • Qweak chambers will have no cryo issues and could use target ladder but there will be interface issues with collimator box
      • How to mount two targets
    • Meeting will be at November 20th at 1 pm
  • Calcium oxidation issue
    • We need a solution for the oxidation : discuss this at the PREX/CREX support meeting?

Misc.

TO DO Lists

  • It would be nice to have real-time viewer for optics studies in commissioning (discussed in 01/16/2014 meeting)
