Agenda

  1. Announcements
  2. Planning for improved beam normalization (TAC runs) - discussion
    • improved limits for low-current operation
    • limits on radiator thickness from halo?
    • effective thickness of wire radiator
    • systematics from collimation restriction
    • systematics from collimator offsets
    • systematics from absorption (simulation)
  3. Planning for fast raster in Hall D - discussion
    • results from early test
    • size of pattern at collimator
  4. Planning of radiators for F2017/S2018 running - discussion
    • JD70-100 : 58um, the one we ran with in S2017, default choice for F2017
    • JD70-105 : 54um, essentially same size and thickness, quality as JD70-100, unused
    • JD70-104 : 20um, proposed for evaluation and testing
