#* Discussion (Jon): splitoffs in MC: it has been brought up across several meetings that hadronic splitoffs may not be modeled in MC well, thus caution is recommended when cutting on number of unused showers. Is there a quick study we could do to point towards this? For FCAL: exclusive omega sample may work. For BCAL: hyperons??

Meeting Time: 11:00 a.m. JLab time

  1. To join via a Web Browser, go to the page [1] https://bluejeans.com/907185247.
  2. To join via Polycom room system go to the IP Address: 199.48.152.152 (bjn.vc) and enter the meeting ID: 907185247.
  3. To join via phone, use one of the following numbers and the Conference ID: 907185247.
    • US or Canada: +1 408 740 7256 or
    • US or Canada: +1 888 240 2560
  4. Upon connection all microphones are automatically muted. To unmute your mike on a Polycom or equivalent unit, enter *4. Unmuting on a computer is trivial as there is a microphone button than can be clicked.
  5. More information on connecting to bluejeans is available.

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 reconstruction efficiency and resolution between data and simulation as a function of E, phi and theta to within 5%.

Action Items

  1. Checks of monitoring comments of Batch 5-8
    1. Timing checks: 72123-72416 (2ns peaks), 72417-72435 (time offset) -> Mark
    2. BCAL gains calibration constants (nominal 8 batches grouped in 4) -> Karthik
    3. Pedestal checks (Primex) -> Igal
    4. Magnetic field in BCAL: check energy calibration -> Mark
