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.

Minutes

Attendees: Elton, Mark (JLab); Zisis, Ahmed (UofR); Sean (NW); Christina, George (Athens); Matt, Joe, Rebecca Barsotti (IU)

1. Announcements
   • Accelerator expects startup on Sep 28 and start to deliver beam to experimental halls during the first week of October.
2. Action Items
3. Activities during the down
   • Sasha will start working on the trigger and will turn on selective parts of the Fcal and Bcal to support the studies.
4. FCAL Update
   1. General updates (Matt)
      • Adesh has moved to Florida and there are several loose ends that need to be picked up
      • Repeating calibration with correct block size
      • Use photons with a narrow energy range
      • Understand the puzzle related to the fact that the measured Fcal energy does not improve with energy. This could in part be due to poor background representation.
      • Add dead channels into the MC. Jared is using the LED data to investigate problematic channels
   2. Timing studies
      • Joe is using the LED data to check time walk, which should be absent in the FADC data. Investigate with LED data with varying intensity
      • Matt is using the sample of clean omegas to check various timing aspects. Looking at timing between particles and the event time. Investigate the optimal time for a cluster. For example the energy average time might be better than the time of the largest block, which is currently being used.
