Kent, KK, Dustin, Seamus, Tyler, Nickie, Ciprian, Rakitha, Bob


  • A CAD step file is available with PREX target ladder and scattering chamber designed according to our simulation geometry elog-2999
  • Tentative time for beam studies would be later November.
  • What are possible targets and maximum beam current
    • Beam current is set probably due to limit the radiation damage to the DVSC-ECAL
    • Kent and KK will talk to Charles about this
  • Dustin will estimates expected rates and lumi widths
    • Dustin will talk to Ed about setting up a gas supply for Lumi
  • We will need a task list with priorities - Kent
    • Moller studies
    • DAQ needs - for now we will have 16 VQWK channels and 16 HAPPEX ADC channels
    • How many pre-amps we need
    • How many ADC channels we need
    • How many BPM/BCM would be available
    • What are the cabling needs
    • What helicity rate we will run? start with 120 or 240 Hz but we would like to go to 960 Hz
    • We will need delayed helicity reporting
    • PAN and online analyzer needs to be ready by the time of beam studies : we will need more man power for this
  • Bob and Rakitha will work on setting up the Injector DAQ


  • Beam parasitic studies needs a to-do list

TO DO Lists

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