  • Hall A Lumi refurbishment discussion by Dustin elog-2968
  • Re: Radiation Around Septum and HRS Area Electronics by Ciprian elog-2967

Paul, Ciprian,Rakitha, KK, Dustin, Kent, Guido, Seamus, Bob


  • New Hall A DS lumi design udate, see elog 2968
  • Goal for new design is to have Qweak design implemented under hall A constraints
    • Compatibility check so far pass all the constraints except Qweak light guide is not yet checked in this new desing
  • The PMT tubes were purged in N2 due to PMT spec. requirement and to keep moisture out of the tube area.
  • Ciprian's preliminary comparison using Happex design for Radiation Around Septum and HRS Area Electronics, see elog 2967
    • This simulation was done at 1 GeV electron beam with PREX-II collimator and PREX-II fringe field
    • Next step will be to simulate at 3 GeV electron beam with PREX-I collimator and fringe field

From Last week

  • Check the PREX beam dump - Lorenzo and Rakitha
    • We may not need to keep tracks after about 3 m into the dump therefore we could add kryptonite


  • 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)
