<ol><li> FDC Update
<ol><li> Package #2 moved to JLab for testing on Friday. Beni already started taking data: first cell has no problems.
</li><li> 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.
</li><li> 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.
</li></ol>
</li><li> CDC Update
<ol><li>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.
</li><li>Gary added another rubber support at each corner of the support rail.
</li><li>We are preparing to move the DAQ electronics in.
</li><li>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.
</li></ol>
</li><li> Installation Details
<ol><li>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.
</li><li>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...
<ol><li>BCAL installation
</li><li>labelling and bundling the FDC cables
</li><li>testing the HV and LV units
</li><li>cable tray installation?
</li></ol>
</li><li>When would the HV and LV crates be available?
</li><li>When would sufficient fadc125 be available for testing with the FDC? June?
</li></ol>
