- FDC Update
- Package #2 moved to JLab for testing on Friday. Beni already started taking data: first cell has no problems.
- Package #1 moved to Blue Crab after testing showed some gas leakage; turned out to be a tube connector on the spacer ring and was fixed.
- Package #3 that had problems with one HV sector on the bottom cell, was opened from the bottom side. A small hair/lint was fond on a wire in this sector. The package was closed and will be tested soon.
- CDC Update
- The gas mixer MFCs were exchanged for larger capacity models and the CDC now has 50/50 Ar/CO2 flowing through at 1100sccm (one chamber volume per day) and exhausting through 6 bubblers into a fume hood.
- Gary added another rubber support at each corner of the support rail.
- We are preparing to move the DAQ electronics in.
- We still need diagrams for the HV mounting blocks and some idea of the weight they would have to support. Lubomir and Beni will send these.
- Installation Details
- Lubomir presented the latest installation schedule for the FDC. Some spikes in manpower (where not enough people were available or only a few people can be on the platform working on a task) had been spread out, resulting in the installation finishing several months later than previously thought (from November to January). This gives considerably shortened time for CDC installation and commissioning; the no cost extension for the CDC work will need further extension.
- We tried to identify tasks which might benefit from extra personnel. CMU's first-year grad students would be available in June/July. For each of the following, would extra people help to complete the task earlier...
- BCAL installation
- labelling and bundling the FDC cables
- testing the HV and LV units
- cable tray installation?
- When would the HV and LV crates be available?
- When would sufficient fadc125 be available for testing with the FDC? June?
