Misc. Tasks and questions

  • Look into the figure of merit of the experiment in the low energy, where the photon beam polarization is low. (To see if constructing an additional tagger is justified). (A. Deur)
  • How well can we check beam charge asymmetry with BPMs?
  • Effect of a beam position-helicity correlation on the data. (M. Dalton)
  • MC simulation:
    • Produce background and main event rates.
    • What trigger(s) to use and what would be its efficiency?
    • Should a beam hardener be used?
    • Check rates quoted in the proposal (once we decide on beam hardener. Presently, the rates are estimated with a 1 MeV cutoff on the photon flux distribution.
    • Determine detection efficiency vs photon energy.
    • Optimize experimental setup
  • Update proposal with: (A. Deur)
    • Add to the list of authors
    • MC Simulation and set-up optimization
