Attending: Elton, Dan, David, Yi, Beni, Tim, Eugene (JLab); Javiera, Will, Alam (USM); George, Christina, Stratos (Athens); Matt (IU); Zisis, Shawn, Tegan, Andrei (UofR).
- Announcements
- Review of Action Items
- Talks at the Collaboration Meeting
- Fcal (Matt)
- UofR work (Zisis)
- Monitoring (Christina if available)
- USM one or two talks? -MPPC / light guides- (Hayk?)
- Monitoring
- Media:BCAL results from first 20 strips 11 09 2012.pdf
- Tested 400 LEDs. Selected 200 LEDs for the first 20 strings
- Output of 200 LEDs are within about 25%
- Ready to ship out 20 strings.
- Checking LED output with integrating light meter close to LED. Repeatability of measurements is very good.
- FCAL - Construction Status Photos
- Frame almost done and ready to ship
- Question to Tim: Problems with making light tight. Should we keep structure at IU and make reasonable modifications? Yes
- Tim, John and Matt iterated on the dark room design
- Plan to use hard plastic for the front wall. Use hard plastic gluing with large overlaps of material for rigidity and light tightness
- Fcal power system shown in photos
- One of four control chassis to power the bases, each powering 700 bases and using 7 of 8 connectors
- Bases.
- Have tested all the ones that are in house. Fixing the couple of percent failures (mostly HV caps)
- Waiting for final shipment of reworked bases from the company
- Eugene: How much time does it take to assemble one module? Answer: about 5 min/module for the beam test, but budgeted about 45 min /person/module in entire assembly to account for collecting material and placing blocks into array.
