Minutes

Attendees: Igal,Bill,Tegan,Arshak,Jon,Liping,Jane,Olga,Tim B.,Sasha,S.T.

• Arshak has finished cleaning up the clean room in preparation for module construction
  • Module construction to resume mass production next week: maybe 4-5 a day?
  • Detector support group getting involved (2 people + possibly more): ESR pre-shaping and module wrapping
• Arshak working on making silicon cookies and LMS (tools ready to go)
• Olga to come to lab, will work on silicon cookies
• Chris S. has all parts for construction of new PMT dividers using Fernando's design
  • To build a few for bench testing starting maybe next week
• Loan agreement with GWU ready to go
  • Equipment for silicon cookie production
  • PMT divider testing
• Tegan presented some photon gun studies focusing on the dip in efficiency at 5 degrees for FCAL2
  • Still not clear what is causing the dip
• Jon reported for Azizah that there appears to be an issue with her samples of events at fixed φ=0 degrees
