Items for followup from previous meeting(s)

1. Requirement of hardware gain matching of pmts for Fcal (and also Bcal)
2. 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.
3. Bcal
   • Web page needs to be setup for communications. A mid-month report is also due. (Zisis)
   • Two components fit for fiber attenuation (Zisis)
4. 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)

Documents to Review

Tentative Agenda

1. Announcements
2. Review of Action Items
3. Calibration/Monitoring
4. Fcal
5. Bcal
   • Status of construction / Readiness Review Schedule
   • Fibre QA: Media:FibreQA_20091001.pdf
6. BCAL Readout
   • SiPM testing - are we ready? (Carl and Fernando)
   • (Elton) Light guide simulations Media:Draw trigs 38deg.pdf Media:Draw trigs 73deg.pdf for segment #2. Entrance rectangle is 3.01x4.0 cm. Exit radius is 1.35 cm. Length of trapezoid/cone is 60 cm, and length of torus is also 60 cm. This configuration should be comparable to Alam's "cylindrical cone" geometry. See also Effective diameter vs B field and angle from Antonelli et al., NIMA 368 (1996) 628-634.
