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. Short term
    1. Richard Jones' work on G3vG4: run photon, pi+, pi-, proton particle guns. Who?
    2. Efficiency study: model mass and t-distributions
    3. Hadronic split off studies
    4. Covariance matrices for photons; should be redone.
    5. BCAL Wiki reorganization -> All
  2. Long term items

Tentative Agenda

  1. Announcements
  2. Action Items
  3. Run Update
    1. FCAL
    2. BCAL
  4. Calibrations
    1. Gain calibrations for all 8 batches Gain_Update (Karthik)
  5. Monitoring
    1. BCAL LED
      1. SiPM dark rate study update[2] (Varun)
    2. BCAL (offline)
      1. Discussion of V16 batch 1-6 (Tolga)
    3. FCAL (offline)
  6. Reconstruction
  7. Efficiency
    • BCAL Hadronic Efficiencies (Elton)
    • Summary: Kinematics between data and MC is reasonable, but not perfect. For BCAL and FCALBCAL, Data/MC differ by up to 8-10% at the lowest energy.
    • The discrepancy between Data/MC has increased since the analysis for the NIM paper.
  8. Simulations
  9. Any other business
