Items for followup from previous meeting

1. Order prototype light guides (Elton)
2. Determine the amplitude vs Npe for the light sensors (Carl)
3. Testing of new modules to determine the range of phoelectrons expected.

Documents to Review

1. Plan for SiPM Testing (Carl and Fernando)
   • Summary of the BCAL Readout Tests Using SiPM Arrays
   • Report on Hamamatsu MPPC arrays

Tentative Agenda: Internal Review of SiPM Option

1. Announcements
2. Review of Action Items
3. Overview (Elton)
   1. Segmentation for all SiPM option Number of SiPMs = (24+16)*2*48 = 3840
   2. Schedule
4. SiPM - update
   1. Electrical Tests (Fernando)
   2. PDE/Dark Rate (Carl)
   3. Acceleration Tests (Carl)
   4. Tests still planned
5. Detailing the SiPM option
   1. Light collection and dynamic range (number of photons expected per sensor)
   2. Cooling / temperature stabilization (specifications)
   3. Output (gain and PDE) stabilization and summing
   4. Geometry model
6. Discussion - path forward
7. Discussion - MOU with USM
