Minutes

Attendees: Elton, Beni, Fernando, Eugene, Sasha, John (JLab); Zisis, George, Andrei (UofR); Matt, Ryan (IU)

1. Announcements
   • FIU will have an openning for a bridge position with JLab with a preference for work in Hall D and announcements have been sent around.
2. Review of Action Items
3. Calibration/Monitoring
   • No report
4. Fcal
   • RFP response submitted to JLab. Full FASTTRACK schedule has been implemented, as well as draft QA plan. Additional work is needed on identifying space needs, documentaion and logging procedures. The goal is to track everything electronically.
   • CR for rad hard glass. We might wish to submit a change request to add Rad Hard glass to the project to coincide with changes to the project due to the fabrication contract. But we need the number of rad hard glass blocks needed.
   • Ryan: Analysis of radiation damage is essentially complete, but there remains some uncertainty in maching "machine units" to rads.
   • PMT procurement
5. Bcal
   • Readiness Review Schedule
   • Construction Status
   • Fibre QA: Shipments 1-5
6. BCAL Readout
   • SiPM testing
   • Light guide prototypes.
7. Simulations
8. Other business

1. BCAL
   1. Readiness Review
      • Schedule and Agenda are nearly final
      • Seven documents have been uploaded to DocDB; a few more will be uploaded by tomorrow.
   2. Construction Status
      • Construction Prototype is machined and back at UofR. An inspection was done at Ross on Thursday: nice! (Minus the serpentine effect). Will be uncrated today and placed on "horse" for optical testing. Inserts will be installed by Friday.
      • Ross Machine Shop:
        • Al bases plates with inserts and bars for first 2 modules at UofR by tomorrow. All 48 being machined now, 50-70 working days.
        • 5 top (inner) plates already here.
        • Alignment pins, bushings, inserts in the pipeline.
      • Shipments: next lead and fibre shipments are scheduled for early next week; ready to receive them. We have 8.3 gallon epoxy kits one hand; enough for first two production modules. 10 more have been orderd for early December, 20 more for the end of year.
      • Spare parts: are on hand plus list for swager has been sent to JLab (outside contract)
      • New storage for lead has been identified (College Avenue Campus) and will be inspected today. This will add to the shelving space in two satellite rooms (LB113.1 and .2), the hallways, the loading dock, our garages at home! Fibres always stay in LB127 or PB113.
      • Press 1 and Swager operating nominally.
      • Press 2 now has its pistons and pressure lines installed. Today/tomorrow we will get the control plate and locking pins. Press operational by tomorrow.
      • 305 lead sheets have been swaged (we need 360 for two modules).
   3. Fibre QA. Shipment 5 analysis is done. Plots on pages 8, 9, 10, 11 of GlueX-doc-1366 will be updated by tomorrow; final report on Shipment 1-5 early next week, then feedback to Kuraray.
   4. New BCAL web site
      • Regina Bcal Web Page
      • Bcal Fabrication Reports
