Seamus, Caryn, Nickie, Bob, Ciprian, Josh, Kent, Juliette, Guido, Tyler


  • Parity run summary by Ciprian
    • Read out beam monitors amd Lumi using VQWK modules
    • Caryn and Tyler looking at data
    • Halo motion mechanism did not work so commissioning did not complete
  • MOLLER commissioning completed
  • 11 GeV send through the Compton chicane but background at the photon detector is above the specifications
  • Radiation Review
    • 10^13 equivalent 1 MeV neutron spectrum requirement was even met during PREX-I where HRS power supplies were kept.
    • PREX-I neutron flux was enough to blow opto-couplers but within the specs for silicon to prevent any radiation damages
    • We need to have a coherent story for why we know PREX-II is better thatn PREX-I
    • Still planning to have the collaboration meeting in end of January or February 2016
      • Priorities are radiation and activation issues during decommissioning, vacuum chamber design, Calcium target will be the serious issues, and various engineering items including septum and scattering chamber design
      • We also need to understand the PREX/CREX acceptance with SOS quads.


TO DO Lists

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