Minutes

Attendees: Elton, John, Will, Yi, David, Mark (JLab); Shaun, Andrei, Zisis (UofR); Matt (IU)

1. Announcements
   • CDC has been inserted into bore of the magnet. Trial cabling is ongoing, which makes access to the upstream BCAL more difficult. It will be backed out for surveys next week.
2. Collaboration Meeting May 12-14
3. Action Items
4. FCAL (John)
   1. Box of bases has been returned to IU for diagnosis and repair
   2. Detector nearing 100% ready, minus 2-3 channels which are misbehaving.
   3. FADC issues
      • New CODA has been provided by Serguei Furletov and is working well. Full checkout installation allows for more control.
      • Many entries with missing data were found to have late pulses by 40 - 50 samples. Timing is being investigated and confusing experts that don't see how this can happen for individual channels (not entire modules)
      • Some FADC channels are still stuck at fixed values
      • High pedestals in some channels have disappeared since new CODA has been installed, although FADC firmware has not been updated.
   4. Matt: Can one tell if failures are simply due to infant mortality or slow continuous failure rate? John: Cannot tell. They have run the system over night with no failures, but found some failures after quiet weekend without taking data. Failures could be due to turning the detector on/off.
   5. David: Asked if BCAL has seen the frozen FADC values. Elton: No, but we have taken very little data.
