Items for followup from previous meeting(s)

1. Beam test
   • Elton to check actual space in Hall B relative to the proposed drawing

Tentative Agenda

1. Announcements
2. Review of Action Items
3. Monitoring
4. FCAL
   1. Construction Status: mechanical, bases (notes from Matt)
      • We received 10 first article COMM boards from Total Electronics.
      • Assembly quality was not superb. The main problem was that the solder was not heated enough (dull and gray instead of shiny). Paul sent them back and we are waiting for a new batch.
5. BCAL
   1. Construction Status: builds, fibre QA
6. Simulations/Reconstruction
7. Beam tests in Hall B (fall 2011) (Kei)
8. Any other business

Minutes

Attending: Elton, Jim, Beni, Yi, Eugene (Jlab); Will (USM); Christine, Stratos (Athens); Zisis, Andrei (UofR).

1. Announcements
2. Review of Action Items
3. Monitoring
   • Updates to paperwork, attempts to add most questions from procurement
   • The recently tested LEDs are going to be discontinued, not unexpected since the uniformity of tested samples was poor.
   • Stratos has found new options on the Osran web page, which will be investigated as soon as George Voulgaris returns next week. These are needed for the Bcal, which requires LEDs shining light parallel to the board.. (The Fcal LEDs an use previously tested units which shine light perpendicular to the board.
4. Light guides. Will inquired as to light guide needs from Athens, UofR and Jlab.
   • Jlab can use up to 40 light guides (old or new dimensions) for gluing tests.
   • Athens originally requested 20 light guides, 12 to place on one side and 4 on the opposite of the Baby cal. They will revisit whether new or old dimensions are required
   • Zisis will revisit the UofR requirements and also if new or old dimensions are required.
5. Beam tests in Hall B (fall 2011) (Kei)
   • IU has prepared documents describing the tests they would like to do in Hall B. However, they just recently found some discrepancies in dimensions and may have difficulty fitting into the upstream alcove. Eugene would like to go forward and let Hall B know that we are considering this, with details to follow
   • Bcal work (Zisis): We have discussions at earlier meeting about instrumenting a baby cal with light guides, SiPMs and mechanical frame. Elton said that it would be unrealistic to try to have this setup by November and suggested that we aim for such a test next spring.
6. FCAL
