## FCAL: Malte provided an update on the base replacement. Failure rate is much lower than last year; preventative maintenance has likely paid off. The pool of spares is 30, with 15 ready to go. The 30 should last until the end of CPP and Chris is working on more boards (5-10/week) which then need a 2-week testing period. Also, there have been 0 lockups (!) so far n CPP. The RL is about the same in CPP as LH2 (5%) and a bit lower than PrimEx (8%). Rate in FCAL is lower during CPP and this might be helping with no lockups. | ## FCAL: Malte provided an update on the base replacement.

Goals for Calorimetry Group
- Determine preliminary photon reconstruction efficiencies as a function of E, phi and theta in data and simulation with a point-to-point precision of at least 5%.
- Measure systematics of pi0/eta mass calibration as a function of detector position to a precision of at least 5 MeV.
- Demonstrate agreement of photon reconstruction efficiency and resolution between data and simulation as a function of E, phi and theta to within 5%.

Minutes
Attendees:Igal, Kevin Saldana, Varun, Stjepan, Jon, Karthik, Malte, Churamani, Tolga, Sean, Elton, Beni, Rebecca
- Announcements:
- Welcome to Kevin (IU grad student)
- CPP run is going ok.
- Zisis is on vacation in July. Malte volunteered to assist Mark in organizing and running the CALWG meetings. Jon can also help.
- Past Meeting Minutes: no review.
- Run Operations
- FCAL: Malte provided an update on the base replacement. Failure rate is much lower than last year; preventative maintenance has likely paid off. The pool of spares is 30, with 15 ready to go. The 30 should last until the end of CPP and Chris is working on more boards (5-10/week) which then need a 2-week testing period. Also, there have been 0 lockups (!) so far n CPP. The RL is about the same in CPP as LH2 (5%) and a bit lower than PrimEx (8%). Rate in FCAL is lower during CPP and this might be helping with no lockups.
