Minutes

Attendees:Elton, Jon, Mark, Adesh (JLab); Ahmed, Zisis, Colleen (UofR); Will, Curtis (CMU); Sean (NW); Matt (IU); George (Athens).

1. Announcements
   1. Zisis: UofR has been supporting UConn to characterize the diamond radiators at the Canadian light source. Tegan and Andrei are helping now. The lab has provided great support. Future runs would benefit from adding a 2nd stage preparation of the beam to streamline measurements.
   2. Elton: The Compton Calorimeter CompCal is in being installed behind the Fcal. The support is located between back of the Fcal dark room and the first row of racks. The CompCal will be an array of Pb glass (~5x5) on a platform on one side of the beam to test feasibility of measuring the Compton signal coming through the beam hole. The plan is to install and connect the detector to electronics for the fall run.
2. Action Items
3. Preparation for fall run
   1. Fcal and Bcal will turn on after f250 electronics is tested and loaded with latest firmware
   2. Zisis: Assume Bcal will run at 1.4 V overbuys and T=5 deg C, as we did in the spring.
   3. Elton: The LED monitoring program by Ahmed should be readied for the run. Ahmed: LED pulsing system was checked for the spring run and found about 5% channels misbehaving. Most problems were for up/down channels during the low bias settings. This is likely an issue with the monitoring system or software, since at high bias the response was as expected. Ahmed is preparing a plugin to use the monitoring system to check the system response.
4. FCAL update
5. BCAL update
   1. Michel Electrons (Zisis for Colleen)
      • Colleen is finalizing a report
   2. BCAL non-linear energy corrections (Will M.)
   3. High energy shower merging (Will M.)
6. Calibrations
7. Reconstruction and Simulation
8. Any other business
