Items for followup from Jan 15 meeting
- Resolution studies (Blake)
- Develop criteria for evaluating resolution studies
- Study impact of inactive material at the end of Bcal on acceptance.
- Check what configuration (thresholds, step sizes, stack? parameters for secondaries, etc) is being used for the Hall D simulations (Regina)
- Writeup fiber handling procedures for review by Kuraray (UofR - draft given to JLab)
- Lead contract completion including lead sizes (Tim - RFI out this week, RFQ out next week)
Documents to Review
Tentative Agenda

Minutes
Attending: USM: Will, Joaquin, Pedro, Edward, Manuel, Alam; UofR: George, Andrei, Kathryn, Zisis; JLab: Elton, Elke, Eugene, Fernando, Beni, Tim; IU: Matt, Mihajlo, John, Joe, Claire, Ryan.
- Announcements
- Welcome USM students: Joaquin Delgadillo, Pedro Toledo, Edward Alvarado, Manuel Mendez, Alam Toro USMphoto
- FCAL Update
- Work progressing on interface between regular LGD and rad-hard LGD. Will likely arrange the blocks in a circular arrangement.
- Discussions between Tim, John, Matt and Elke agreed to rough division of responsibility on the construction of the support structure and dark box (to be described in the MOU):
- John will produce detailed drawings (for review)
- Conceptual design for dark room (details are not needed for a while). Dark box to be fabricated on site at JLab
- IU to fabricate support structure.
- BCAL Update
- Bcal construction schedule (Regina)
- MOU circulated to UofR Research Services and Deans office
- Internal memo describing space requirements
- Holder for fibers and tester to be completed today
- Issues concerning customs and taxes - discussions ongoing regarding import/export of fibers and SiPM
- Will suggests that we keep Chile in mind in these discussions. He will investigate options in Chile regarding loans, donations, transfers, etc.
- Bcal construction schedule (Regina)
- BCAL Readout
- Roadmap toward a decision for Bcal Readout
- GlueX-doc-1214 Performance of SiPMs below room temperature
- Energy threshold for various assumed PDE and DR combinations
- Discussion
- USM: Consider what SiPM cooling measurements can be done in Chile
- Current setup in Chile includes small dark box, ADCs, power supplies. About 80% of hardware for simple tests to date.
- USM is reviewing a possible 'alternative' design for readout. This includes light transmission, effect of B-field on readout. Plan is to develop a conceptual design for comments and feedback. Suggestions for tools for studying light collection. Elton, Matt and Zisis to send information regarding tools which have been used for studying light collection.
- Simulations (Blake et al): a progress report is expected at the next meeting (Feb 19) and a written one not long after.
- Matt: Add hooks to code so that DR and PDE can be provided as input parameters.
- Any other business
