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.

Tentative Agenda

  1. Announcements
  2. Calibration
    • Notes from Christina (she cannot make the meeting today): We have been able to shield the laser and have obtained very clean pulses,now we are checking on their stability.
    • One question which should be answered soon mainly from Tim:will there be any space for the LED drivers or we should abandon this effort?Or should we try for smaller?
    • Progress on filling in the Calibration Specification Table.
  3. Fcal
    • Mihajlo will show slides of his APS presentation on timing
    • Other updates
  4. Bcal
    • Decision on lead thickness -- Updates on sampling studies.
      • I do not think can afford the time to change the lead thickness. Comments?
    • Roadmap to decision on Bcal readout e-mail
    • Updates on resolution studies (Blake)
    • Visit to Alberta
