Minutes

Attending: Sean (NU); Curtis, Mike S., Will M., Naomi (CMU); Simon, Beni, Adesh, Lubomir, Alex B., Luke, Elton, Justin, Mark I., Nathan (JLab); Mahmoud (FIU)

  1. Calibration Data Taking
    • Sean has started updating the list of cross sections for processes that can be used for calibration,
    • Sean and Adesh will discuss updating the estimate for the amount of FCAL data that is needed.
  2. Calibration Tasks
    • The Performance Summary is looking good, except for a few missing sections.
    • Sean highlighted the need to update variances and make sure that they properly propagate through the code.
    • Sean gave an overview of the meeting that was held yesterday to discuss the Calibration Challenge. There was good discussion of goals of the exercise. The difficult part of the exercise will be the details of integration, and these were discussed as well. Sean is organizing some test runs, and a meeting is planned for next Friday to review progress.
  3. Subdetector Reports
  4. Future Simulations
    • Mark ran some simple test jobs, and Sean checked to see that their output was broadly reasonable.
    • Yesterday, Mark, Justin and Sean had a discussion, and agreed to only run bggen simulations (no beam-only), and to increase the photon energy range to E(gamma) = 4 - 12 GeV. This increased range will allow us to study if events from lower photon energy are leaking into physics analyses looking for events generated in the coherent peak, and to study exclusive events that have larger cross sections at lower photon energy that can be used for calibrations.
