Tentative Agenda

1. Announcements
2. Review of Action Items
3. USM report
4. [Bcal Readout Review (July 21) Recommendations
   1. Develop a comprehensive test plan for the expected 10 units of SIPM assemblies from Hamamatsu and SensL, including the testing of long term stability and reliability, and operation at close to realistic (radiation) conditions.
   2. Make the choice of photo-sensor system for the BCAL and place an order only after obtaining and analyzing the results of the above tests. The Committee is aware that this could cause a few months delay of the fabrication/installation schedule, but considers the tests and analyses to be of higher value.
5. Plan for SiPM Testing (Carl)
   • GlueX-doc-1320 Test plan for new SiPM arrays
6. Simulations
7. Discussions on MOU with USM
