Items for followup from previous meeting(s)

1. Monitoring
   • Specifications for BCAL Monitoring R&D (Zisis, Elton, Christina)
   • Zisis will gather Andrei's tests and overall ideas for BCAL monitoring system.
   • IU: checking cross talk of calibration inputs across modules.
2. Fcal construction
   • Matt to provide optimum schedule for shipping completed blocks to JLab based on technician work plan.
   • Zisis/George to send Elton shipping specifications as example for specifying Pb shipments
   • Mechanical: Tim has promised review of support structure.

Minutes

Attending:

Attending: Elton, Yi, tim, John, Beni, David, Tim, Elton (JLab); Zisis, Andrei (UofR); Ryan, Matt (IU); Christina, George (Athens); Will (USM).

1. Announcements
   • Zisis and student will present talks on the Bcal and proposed SiPM studies at the The 46th Winter Nuclear and Particle Physics Conference
2. Review of Action Items
3. Calibration
   1. Questions about on how to proceed with project
      • Fcal: Matt proposed that a drawing of the FCAL with the plexiglass be put together and sent to Athens (and others) for comments and suggestions for connections to LED sources. Tim can suggest thickness of plexiglass necessary to maintain rigidity.
      • Bcal: Likely path will be using LED sources with connections to fibers which actually get attached to the light guide. Zisis will summarize measurements at UofR.
   2. MOU
      • Christina has sent around an update to their MOU, which includes Stratos Anassontzis, assistant prof, who has agreed to joint the project! He was responsible for the Barrel RICH calibration system of DELPHI with fibers!
