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)
