- Monitoring.
- PC boards shipped to Geneva, before transferring to Athens. Should be populated in a couple of weeks.
- George is preparing a test setup
- The invoice from Athens has been signed, but the CERN account has changed and this has been corrected. We hope it will not have an impact on payment schedule.
- FCAL
- Updates will be presented at the collaboration meeting
- BCAL
- BCAL Beam Tests 2012
- Elton presented the beam test request to Hall B yesterday.
- We have been instructed to work with Eugene Pasyuk and Doug Tilles to install equipment.
- Elton, John, Tom and Josh went down to the hall this morning to plan where to locate the mini-Bcal ectype and how to place it there.
- The beam test will be presented at the collaboration meeting.
