Revision as of 12:02, 15 November 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.

Participant Direct Lines

• JLab Phone in CC L207 is 757-269-7084 (usual room)

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: Will explain progress after analyzing and playing with JEventProcessor plugin.Cannot promise final plots unfortunately due to various reasons.

1. Complete after new launch
2. 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.

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%.
