Agenda

• New Scattering Chamber Shielding Update - 2 elog-2987
• PREX: planning for review elog-2986

Present:
Kent, KK, Seamus, Tyler, Guido, Paul, Juliette, Rakitha, Dustin, Bob

Minutes

Minutes

• Need to test CREX compatibility with PREX collimator (Rakitha, Kent, ??)
• The goal for next collaboration meeting will to converge on final design including new SC + shielding design, new SC material, collimator box material
• We need to decide materials for new SC, collimator box, and septum pipes (Al vs. steel)
• Bob will look into getting a TOSCA model for Juliette so that she can modify it include the magnetic shielding to reduce fringe magnetic field to the levels assumed in the Geant4 simulations
• Need to add collimator drop-down box and collimator disposal box at the bottom into Geant4 simulation
  • If CREX is compatible with PREX collimator we will not need a collimator drop-down box
  • The drop-down mechanism must be designed not to interfere with the sieve actuators
• We need to test the CREX septum current limit
• Another important item is to look in to Q1 compatibility between PREX/CREX Bob? Seamus?
• Compare angular neutron distribution in the hall for Happex similar to analysis in elog 2954
  • what are prompt single event upsets due to high E neutrons for PREX vs. Happex
• Collaboration meeting time will not be in August but sometime in September not earlier than September 18th.

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)
