Minutes
Attendees:Elton, Tim, Yi, David, Beni (JLab); Kei, Matt (IU); Zisis, Andrei (UofR); Will, Hayk, Alam, Elias (USM); Christina, Stratos, Pavlos (Athens)
- Announcements
- News media event in Valparaiso will happen this morning.
- Action Items
- Monitoring
- Almost all material in hand
- LEDs have not yet arrived. (Note: Zisis said that they were shipped 8 days ago and expect arrival in a few days)
- Boards will start soon and be tested for functionality. Athens will check pulse sizes relative to requirement.
- Stratos will work on the plexiglass specs. Once testing is completed, a piece of the prototype in Athens will be shipped to JLab as a sample.
- FCAL
- Stacking is proceeding very well. Expect completion at the end of the week or early next week,
- Zisis: Plan a photo shoot for the final block. (Elton will ask Greg Adams to take photo).
- Bases are being completed slowly.
- Drawing package on the dark box has been completed. Welds on the aluminum structure, which must be derated, have been replaced by bolted connections.
- Tim: Has seen the model. Drawing numbers were issued yesterday. Drawings will be entered into the JLab system before installation.
- Kei: Draft on NIM paper from beam test has been circulating. Matt, Kei and Elton stayed after the meeting to go over recent comments.
- BCAL
- USM Report File:20130326.pdf
- All measurements have been completed at USM. The next-to-last box (640 sensors) should have arrived yesterday at JLab. The last shipment (370 sensors) was sent out yesterday.
- The 3 non-conforming sensors will be shipped to JLab. Jlab will return them to Hamamatsu for replacement.
- Final testing on the forty original sensors on loan to USM (from the first article) will be completed in the next week and they should be shipped back in about a week. They will make linearity measurements on these sensors.
- SiPM Measurements at Regina
- Good progress has been made on PDE measurements
- Recent measurements are consistent with original data from Mernoosh. SiPM and diode are being flipped in position to check consistency.
- Have completed measuring 7 or 8 sensors, the remaining will be measured this week. Measurements are taken at 0.9 V above breakdown. If time permits, other measurements will be taken at different biases.
