Agenda

  1. Announcements
  2. Photon beam issues encountered during this run - discussion
  3. Photon beam properties
    • harp scans
    • beam energy monitoring
    • beam current and position
    • beam normalization from TAC run
    • beam polarization with TPOL
  4. Options for reducing photon beam flux during TAC runs - discussion
    1. reducing beam current below 10nA (requires work by accelerator experts)
    2. thinner radiators (wires, carbon fibers, nanofoils)
    3. pin-hole collimator insert (MC study of collimator halo)
    4. systematics associated with each of the above
  5. Study of PARA/PERP polarization offset from beam-collimator misalignment - Richard J.
  6. Photon beam-related program @ 6 GeV, if we can get it - discussion
    • TAC run systematics studies
    • align, take data with 20 micron diamond
    • fast raster for active collimator calibration, beam spectrum profiling
  7. Update on TAGH calibrations - Nathan S.
  8. Update on TAGM calibrations - Alex B.
  9. Update on PS calibrations - Sascha S.
  10. Any other business
