Agenda

  1. Ciprian: septum pipe slides
    • CG: Jay made an implementation that shows almost complete reduction of the fringe field at the center of the Septum for CREX.
  2. Ciprian: dump configuration, radiation calculation slides
    • GU: to verify that the thickness of the PREX1 apperture plate/diffuser is to blame for the increased radiation damage we should run with a thinner apperture (like the PREX2 donut) and see what we get.
    • SR: it looks like a larger apperture and shielding would be the ideal configuration. We should include the new fringe field from Jay to see how it changes things (it should improve things significantly).
    • PS: Do we know where PREX1 damage came from (target, collimator, dump, beampipe)? CG: don't have numbers on hand now, will look it up.
    • PS: could you provide NEIL vs energy distributions for e/gamma and neutrons? CG: will update slides and send them over later today.
