Agenda

• Radiation Around Septum and HRS Area Electronics by Ciprian elog-2969

Present:
Paul,Ciprian,Rakitha, KK, Dustin, Kent, Bob, Seamus

Minutes

• Ciprian analysis was started to address the Thia's concern that order of magnitude reduction in radiation wrt to PREX-I is only relative. Therefore simulation was done to compare with LH2 target at 3.08 GeV (HAPPEX setup)
• This simulation results shows that the increase in the radiation for electron hut areas are minimal in PREX-II wrt HAPPEX setup
• One issue that still concerns us related to what damages PREX-I has done to the hall.
• Bob was able to look at faults occurred during PREX-I by looking at halog entries.
  • It would be nice to do similar fault count during HAPPEX running
  • Also look at fault count during PREX-I followup experiment (deuterium target with 5% heavy radiator )
• It should be noted that PREX radiation issues mainly arise due to narrower aperture septum beam pipe and fringe field issues that were not present in other Hall A experiments.
• Compare the power dumped into the hall A in PREX I and II and also HAPPEX and deuterium experiment that followed the PREX-I experiment
• PREX-II budget list budget_prexII
  • We need similar budget for CREX now

Misc.

• 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)
