Revision as of 11:14, 13 December 2018

Meeting Time: 11:00 a.m.

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.

Action Items

1. FCAL: Cross check MC changes by Richard to make sure that gains are not affected in both Geant3 and Geant4 (Matt/IHEP)
2. Fix FCAL online monitoring plugin to properly plot low level digi quantities in 2D displays. 2D display of pedestal is hard to get because occupancy plot is filled in a different loop. (Tolga)

Tolga: Progress update in this study posted here: [2] I will try to attend the meeting but have been feeling under the weather. If I decide to rest during the time I apologize, but the slides are here for the Cal group's reference and convenience.

1. BCAL: Check pulsing rate of LED triggers when FP trigger bit is missing (start with early runs in fall 2018). With discerning software, check pulsing rate of later runs where it appeared that the downstream FP LED bit was not firing.

Long term items:

1. From Mike's work: -cos(phi) type dependence in the data and a phi dependence at the downstream end of the bcal. See Sep 21, 2017 Calorimeter Meeting.
2. FCAL: It has been noticed that the pi0 mass shifts when the LED pulser runs at high rate. This is still not understood. See Log Entry 3595928 and references.

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 east 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%.
