Items for followup from previous meeting(s)
- Cables
- Review cable labels for Fcal (Matt) and for Bcal (Zisis)
Tentative Agenda
- Announcements
- Review of Action Items
- Monitoring (Athens)
- Order of new control boards has not yet gone out due to Easter holiday.
- JLab will also order components and additional control boards
- Need to find out about shipping SiPMs to Regina for eventual delivery to Athens.
- Cable Labels
- Cable labeling is under discussion for the Fcal. Fernando plans to have all ends, including readout electronic slot/channel labels. Matt supports this decision.
- Discussion regarding complete labeling to provide flexibility at final connections.
- This need to be completed for Bcal also.
- FCAL
- Construction Status
- Samples of conformal coating from third party company not yet provided
- Coating from company have been received and need additional touch up, which will be done at IU
- Eugene: Asked about range on Flash. This should be decided with assistance from beam data.
- 2011 Hall B FCAL Beam Test (John)
- Accelerator is at 0.879 GeV/pass, 3-pass to Hall B. On Friday they plan to move to 5-pass on Friday. Following Wednesday the accelerator will return to 1.16 GeV/pass
- Fcal plans to stay in the alcove to take data at all energies.
- Also need to change FADC readout mode to sparcification and move away from raw data mode
- Construction Status
- BCAL
- BCAL Beam Tests 2012
- mini-Bcal moved to EEL about 10 days ago, cabled up and took about two days of cosmic-ray data
- Prototype moved down to Hall B last Tuesday.
- Hooked up to DAQ and took some data over the weekend (see example below)
- The cooling circuit had a blockage, but this was fixed yesterday. Temperatures are stable at chiller T= 14 deg C, upstream T=17.5 deg C, downstream T=14.5 C
- Accelerator is in the process of restoring beam at 3 pass. Will resume data taking when beam is stable.
- BCAL beam test: fadc amplitudes upstream end
- BCAL beam test: downstream end
- BCAL Beam Tests 2012
- USM update
- File:USMUpdateJaviera20120410.pdf (Javiera)
- Production is ramping up and USM should be able to test at almost twice original production rate
- Already have more than 500 tested units. Plan to ship in about a week after all data has been digested.## File:USMUpdateOrlando20120410.pdf (Orlando)

- We need to start revising Chapter 4 Detector, Section 4.3 Calorimetry.
- Calibration of Calorimeters
- Simulations/Reconstruction
- Any other business
