Teleconference Time: 11:00 a.m. EST

  • ESNET (Number is 8542553) and SeeVogh session (GlueX Calorimetry meeting room)
  • Phone connection only upon request.
    • +1-866-740-1260 : US+Canada
    • +1-303-248-0285 : International
    • then enter participant code: 3421244# (remember the "#").
    • or www.readytalk.com (and code without the #)

Participant Direct Lines

  • JLab Phone: in CC F326 is 757-269-6460 (usual room)
  • JLab Phone in CC L207 is 757-269-7084
  • Phone in the Regina Videoconference Suite is 306-585-4204

Items for followup from previous meeting(s)

  1. Revisit raw data format for Flash-250 MHz following Flash-125 MHz discussion. (all)
  2. Upload documentation for interlocks and monitoring to Doc Db (Dan) See GlueX-doc-2342
  3. Check that latest edits of TDR have been checked into svn (Zisis) Zisis has uploaded the latest updates to svn

Tentative Agenda

  1. Announcements
  2. Action Items
  3. Monitoring
  4. FCAL
    1. FCAL Calibration
  5. BCAL
    1. Update on liquid sample on Readout Assembly used for testing (001)
    2. See Sep 24, 2013 Calorimetry for background information.
      • File:Readout001 Analytics.pdf Report indicates propylene glycol is the main component in the liquid, which is the additive in the anti-freeze coolant we were using. The liquid was found on the #1 modules used for testing of modules after gluing light guides.
    3. Cosmics: Media:TDCcalculations.pdf
  6. Reconstruction and Simulation
  7. TDR update
  8. Calibration of Calorimeters
  9. Any other business
