1. Announcements
2. Review of Action Items
3. BCAL Beam Tests 2012 - Updates since last week(Elton)
   1. Beam schedule in Hall B is being modified to account for loss of polarization in the new target installed last week. The plan is to run photons this week and return to electron beam next week. Schedule is fluid.
   2. Mechanical: Tom Carstens and team placed the mini-Bcal onto its support structure and practiced moves that will be required in the Hall to mount the prototype.
   3. Cables have been labeled and bundled. VXS and NIM crates have been mounted in racks in EEL 126 in preparation for cosmic testing
   4. Readout packages (SiPMs, cooling plate, preamp/summing board, temp compensation board, connectors) have been assembled. Testing is in progress.
4. Update from USM
   1. Production Manager Report (Javiera)
      • New personnel hired and progress reported since last week
      • The USM data base information was added to Yi's wiki page.
   2. Comments on lightguide Status (Iñaki)
      • Checking sizes of light guides
      • Found problem with dimensions
      • Start to systematic measurement of light guides on Thursday using a "profile projector" (According to Tim projects guides on a screen and allows precise measurements without touching the light guides.
      • Production of light guides with the large 5-axis CNC machine started last week. However a part failed, and will be delivered Friday.
      • The surface finish of the new machine is much better than for the 80 first articles and will save polishing time.
   3. JLab will produce tooling gauges to check overall dimensions of light guides. Will requested that we make two sets, one for USM. We will consider this request when the drawings are made.
   4. USM Web Interface to DB
5. Status of Testing at JLab
