Minutes

Participants: Curtis, Naomi, Beni, Lubomir, Simon, Elton, Mark

1. Announcements - FPGA tutorial at online meeting this afternoon; thought to be no damage to Hall D from weekend's flooding.
2. FDC Update
   1. Third package moved to 126 for testing: gas, noise, HV are OK, except one negative HV sector (for field wires). Beni: problems with some translator boards and Linux DAQ, but other than that very good signals, TDC spectra indicating no oxygen.
   2. Corrosion: in the last test at close to 100degC and humid environment for one week, one sample with Viton and vacuum grease developed corrosion visually, but no change in the conductivity. We will repeat the tests with the right pressure on the O-ring.
   3. To keep to the cathodes in flat position during production and testing, special tool was developed; now we will continue with the cathode production.
3. CDC Update - ring G was completed earlier this week; the nonmagnetic wire is now being used (the center conductor is silver instead of stainless steel, otherwise identical); we are working on a startup procedure which a student will help to develop and test
4. TDR Update - we need to check in revisions.
5. Calibrations
