Attendees: Sasha,Susan,Zisis,Phil,Arshak,Igal,Bill,Jon,Olga,Azizah,Jane
- Preparation for module fabrication and fabrication itself continues
- Received support from 2 members of detector support group: ESR shaping and module wrapping
- Grand total as of meeting was 144 fabricated modules
- Will soon need to move crystals and fabrication area to a different building
- Some discussion of testing the modules, including using beam in upcoming CPP/PrimEx runs
- Build 5x5 stack?
- Arshak working on LMS
- Contacted Carl Zorn regarding using his setup for checking transmission of light through plexiglas sheet -- equipment not working yet
- Igal described student project 5 for dark matter searches
- Azizah showed photon gun reconstruction efficiency as a function of φ
- Holes at 0, 180 degrees probably due to gap between crystals
