Goals for Calorimetry Group

1. 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%.
2. Measure systematics of pi0/eta mass calibration as a function of detector position to a precision of at least 5 MeV.
3. Demonstrate agreement of photon resolution between data and simulation as a function of E, phi and theta to within 5%.
4. Demonstrate agreement of photon reconstruction efficiency between data and simulation as a function of E, phi and theta to within 5%.

Minutes

Attendees: Igal, Sean, Jon, Malte, Eugene, Sasha, Zisis

1. Announcements: Zisis announced that the baby BCAL is now at ANL, on load from JLab for a period of a year.
2. Past Meeting Minutes: nothing to review.
3. Review Action Items: will review these at our next meeting. Igal noted that Ilya is at JLab now and will likely work on uploading the constants in the next week or so.
4. Detectors
   1. FCAL/ECAL: Malte reported that FCAL2 lead glass has all HV and signal cables installed. All 4 plexiglas panels are installed, two have the LEDs on them. The critical one was bottom left (as seen by the beam) as this needed to be completed for the ECAL LMS fibers to go on.
   2. BCAL: Zisis reported that Regina will aim to complete the BCAL SiPM dark rate study during the summer.
