Video Conferencing Information

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. Add new gain calibrations to ccdb (Tegan) Preliminary constants added about three weeks ago.
2. Homework from NIM paper. Non-linearity correction of SiPMs (Elton)
3. Enrich pi0 skim with layer 3 events (Tegan with support from Sean/Mark)
4. BCAL: Create non-linearity corrections for MC for gain adjustment.
5. BCAL fixes: Hot TDC channel

Complete after new launch

1. Report back on study of eta with in FCAL [Mark] Lost track of specific reason for this item. Presumably interest in evaluating FCAL calibration for an independent set of data from the pi0 used to calibrate. Also, the eta mass resolution is only weakly dependent on the position resolution (unlike the pi0). Finally the eta pi+pi- final state can use the vertex obtained from the charged pions to determine the vertex. Pass this check onto the FCAL group.
2. From Mike's work: -cos(phi) type dependence in the data and a phi dependence at the downstream end of the bcal

Minutes

Attending:Elton, Simon, Colin, Mark (JLab); Tegan, Zisis, Ahmed (UofR); Christina (Athens); Sean (FSU); Tolga (FIU); Jon, Jared (IU); Curtis (CMU)

1. Announcements
   • None
2. Action Items
   1. Gain update / skims (Tegan)
      • Reduced skims have been created from the original skims to shorten iteration times. But a bug was found and new reduced skims are being produced.
      • Preliminary 2018 gains for the BCAL were entered into ccdb about three weeks ago.
      • Gain matching will be conducted using a tagged version of the code so that changes are confined to differences in the constants.
      • Sean: Suggested that Tegan use the tagged version from the Workfest. This one is stable and will be used as a basis for the next reconstruction launch.
