Minutes

Present: Curtis, Naomi, David, Lubomir, Mark Ito, Eugene, Mark Dalton, Beni

1. Announcement
2. Collaboration Meeting
   1. One talk is enough for each detector, Lubomir would like 20 minutes on cluster counting
3. FDC Update
4. CDC Update
   1. We discussed monitoring CDC preamp temperature. For the FDC the coolant temp will be monitored. For the CDC it would be easier to monitor the air temp near to the preamps than the preamp chip temp itself.
   2. There is a slight difference (few ns) in measured time between the 3 fadcs, probably due to their clocks not being synchronised.
   3. The drift times are showing spikes, common to all channels on the same HVB.
   4. It looks like one channel disappeared between runs; the raw data are all zeros (no noise) so the pedestal probably dropped.
5. Data Formats
   1. David will contact Cody to find out if our proposed data format is reasonably achievable.
