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%.

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
