Contents
Items for followup from previous meeting(s)
- Requirement of hardware gain matching of pmts for Fcal (and also Bcal)
- Fcal
- John iterating on support frame. Key load-bearing tubes, currenlty Al, could they switch to iron? Tim needs to weigh in on this one.
- Need to discuss strategy for fabrication of boards. Paul is concerned primarily about the HV board. We should include Fernando and Chris on the discussion for suggestion of production.
-
Fastrack schedule: Matt asked if Fasttrack has a facility for "resource leveling". Does anyone know? - Magnetic shield tests? (Tim needs to provide feedback)
-
Eugene: Fcal activity on calibration is scheduled to start next month. We need to formally address it.Elton and Eugene working on CR to modify schedule for a few activities.
- Bcal
- Web page needs to be setup for communications. A mid-month report is also due. (Zisis)
- Two components fit for fiber attenuation (Zisis)
- Bcal readout
-
Provide information on FM pmt cathode diameters (Elton) - Slide 8: Matt Suggestion: Plot efficiency vs. a specific angle to understand behavior. (Alam)
- Review decision on the orientation of FM pmt relative to Bfield, including tolerances due to expected field changes. (Elton, Will, Alam, Pedro)
