- SICCAS crystals
- Preparation for module fabrication
- COMCAL tests, TAC running, etc.

Attendees: Sasha, Varun, Zisis, Jared, Jon, Tim B., Phil, S.T.
- Initial QA (visual inspection + dimension checks) have been completed for almost all of 2nd batch of SICCAS crystals
- 20 crystals still need QA checks
- Plan to check transmittance of ~20 crystals using Carl Zorn's lab
- Focus on discolored crystals first
- Compare measurements to those done by Chinese company/ Jane
- No progress reported for PMT divider development
- Module construction ready to go once QA completed
- Igal posted two plots comparing measured π0γγ distribution to MC for FCAL and FCAL-II
- 3 out of 4 clusters θ<4.5 degrees
- No π0 mass constraint
- Clear signal peak seen for FCAL-II simulation, no visible signal for FCAL simulation
- Sum of MC contributions have the same general shape as real data, but do not agree in detail.
- No progress reported regarding loan agreement with Regina
