Items for followup from previous meeting(s)

  1. Calibration/Monitoring
  2. Fcal
    • Specify the number of Rad Hard blocks to writeup a change request to the project.
    • Investigate mechanical issues associated with supporting lead glass on top of shashlyk modules (Lubomir, Serguei). Will to send drawings of the modules.
  3. Bcal
    • Specify the normalization and dynamic range for the number of photons/GeV in showers
    • Decide on specific grouping for SiPM sums
    • Possibility of using air gap for SiPM coupling
    • Finalize shapes of "Winston guides"
  4. Simulations:
    • List of energies and angles to be simulated for the purpose of establishing the dynamic range of light to the SiPMs.

Minutes

Attendees:

  1. BCAL
    1. Construction
      1. All equipment operating nominally. Builds growing within tolerances.
      2. Mod 04 to RMS today or tomorrow; Mod 05 at 50%, Mod 06 at 10%. Two new crates arrived yesterday.
      3. Mod 02 and 03 machining most likely finished.
      4. Lead tally nearly done; some discrepancies. Will communicate with JLab and Vulcan today.
      5. Enough epoxy for 2.5 months on hand, 9 gallons back ordered.
      6. Shipping insurance sorted out and waiting to meet with shippers and get new quotations.
    2. Fibres
      1. Shipment 8 done and 100 fibres from No. 9 (see above links). Means shifted for shipment 9, for both Npe and atten length. Most likely a real effect but we're checking.
    3. RMS visit: March 5.
      1. Final contract will be given to RMS tomorrow.
      2. Inspection and pictures of Mod 02 and 03 machining.
      3. Transmission uniformity test on Module 01.
