Items for followup from Sep 29 meeting

  1. Mijahlo will show slides for APS meeting at next meeting.
  2. Each subsystem must complete blanks in the Calibration Specification Table.
  3. Decision on Bcal sampling fraction needed if any changes are to be made to design. NEED A DEADLINE
  4. Resolution studies (Blake)
    • Up-to-date geometry ONGOING.
    • Decreased threshold for FM pmts. ONGOING
    • Position resolution - understand dependence on granularity.
    • Different segmentation for the outer section. - LOWER PRIORITY
  5. Study impact of inactive material at the end of Bcal on acceptance.
  6. Add F100 rad hard glass to simulation. - New graduate student has been assigned this project.
