Items for followup from previous meeting(s)

1. Calibration/Monitoring
   • Geometry for inputing monitoring sources into Bcal (Media:mom_gamma_log.png)
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. 1. BCAL 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).
