Minutes
Attending: Yi, David, Tim, Beni, John, Elton (JLab); Christina (Athens); Alam, Hayk (USM); Zisis, Andrei (UofR).
- Announcements
- Review of Action Items
- Monitoring.
- Geometry
- Monitoring contract has been placed
- Media:IMG 0794.JPG
- Media:IMG 0793.JPG
- Photos show that there is room for the Bcal monitoring board.
- Light guides
- Christina is unsure precisely what light guides they received from Chile.
- Next steps
- Mount opposing 4 light guides (2 on each side) of miniCal to study cross talk
- Elton: Fernando has promised to order more compact electronics with summed output to make available to Athens.
- Beam tests in Hall B (fall 2011) (John)
- FCAL
- Construction Status: mechanical, bases (notes from Matt)
- Beam test (John)
- Prototype is on travel tomorrow to JLab
- Expect to install on Thu
- Quick cosmic tests on previous weekend and showed that prototype can be successfully connected to Flashes. Found one dead channel, which should get fixed before installation into Hall B.
- Sasha is testing 3 flash modules in a crate at JLab, and is working with Sergey Boyarinov to integrate the system into Hall B.
- Notes on Elog: Yi is implementing a new elog which will be made available once security issues are resolved.
- Beam test for Bcal (preparations)
- The mini-Cal is under construction (layer 11) and should be done in another week.
- Student labor will be dined next week after completion of the work for this project.
- Eugene: Asked about measurements of the mini-cal at an angle to the beam. Zisis: Simulations were done down to 20 deg and full containment is demonstrated.
- Wiki pages are being updated
- BCAL
- Construction Status: builds, mini module
- The top plate on the 49th module was added yesterday. yeah!
- Machining of the last five modules will start next week and should be completed before Xmas.
- The current plan is to ship modules 45-49 + the mini-cal with beam test equipment in one final shipment. The truck will be a refer truck and five modules cannot fit side-by-side. They are considering the best way of adding a 5th module to the shipment. One possibility is to stack two of the modules.
- Fibres
- Fiber testing will be completed next week.
- Summary report will be drafted in December
- Construction Status: builds, mini module
- USM update: [2]
- Demonstration of the new web site failed during the meeting.
- A test time to check external access to the web data base will be tried next Monday.
- Simulations/Reconstruction (David and Andrei)
- Draft document by Zisis to support the addition of one additional layer to bcal is being reviewed
- Simulations have been conducted to study neutron/photon separation, proton/pion identification, position resolution, etc.
- Zisis should be able to make changes before next week, but will also make the source available to David for editing.
- Andrei is preparing plots of the neutron rejection vs photon efficiency for the two configurations.
- SiPM testing at JLab
- Preparations are close to complete except for the electronics
- Fernando estimates that the boards should be available next month.
- Analysis of the data from the last shipment of SiPM from Hamamatsu to JLab shows some outliers and are under evaluation.
- Any other business
