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: Susan, Tolga, Malte, Karthik, Sean, Varun, Mark, Zisis

1. Announcements:
   • the experiment resumes, Jan 12-Mar 22, 2023.
   • Zisis wil be at the lab, Jan 16-26.
2. Past Meeting Minutes: no review.
3. Review Action Items: no review.
4. Run Operations
   1. FCAL/FCAL2: Malte reported on the stress-test of the FCAL bases over the holiday break. The voltages were taken up to 1800 V, in a stepwise fashion. Some failures occurred; see: Log entry 4104588.
   2. BCAL: Varun (with Mark's help) took LED data before Xmas, at 5, 10 and 18 C. Stjepan will analyze the data and report. Similar data will be taken at the end of March with the aim of a technical report over the summer.
   3. CCAL: no report.
5. Calibration: no report.
6. Monitoring: a short discussion took place on the PrimEx monitoring launches. Sean reported that the 2021 monitoring is complete and a production launch will follow. The 2022 data monitoring will happen once all the necessary calibrations are in place.
7. Reconstruction: no report.
8. Simulations: no report.
9. Any other business: none.
