Revision as of 09:47, 1 October 2009

Meeting will be dedicated to Calibration and Monitoring

Teleconference Time: 11:00 a.m. EST

  • ESNET and EVO session
  • Phone:
    • +1-800-377-8846 : US
    • +1-888-276-7715 : Canada
    • +1-302-709-8424 : International
    • then enter participant code: 77438230# (remember the "#"). Note: code changed 7/2/09

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)
