Items for followup from previous meeting(s)

1. Monitoring
   • Circulate for comments a concept for distributing monitoring inputs to the control boards (Elton) See e-mail
2. Simulation
   • Add up-to-date geometry for plexiglass pane and TOF detector and rerun simulation to check photon reconstruction (Elton to see if Beni or Richard can add the geometry) Beni has agreed to do this.

Tentative Agenda

1. Announcements
2. Review of Action Items
3. Monitoring (e-mail from Christina)
   • I am out of town today and cannot participate but I can report the following:
   • The plexiglas FCAL measurements came to the conclusion that the main irregularities are due to the two surfaces which are opposite the the LED's (the ones which would be touching the other quadrants) and were not polished. It seems the diffused light there close to the surface is up to 5 times more than everywhere else. So next comes the polishing of those sides and re-measurement but our technician is on strike, so we have to wait.
   • Otherwise sorting of BCAL LED's goes on and the BCAL bare Control Boards have arrived in Gva as well.
4. FCAL
5. USM update
6. BCAL
   • Radiation exposure to SiPMs during Hall B beamtest (Ivan)
7. Simulations
8. TDR update
9. Calibration of Calorimeters
10. Any other business
