Can someone please remind me where the drift velocities are stored? I would really like to know what they are, but cannot seem to find the information. Please help!

Long store, usable beam from midnight until 6:30, low background, i.e. H1 and H2 scalers with rates that decreased steadily from 20k/s to 3-4k/s. 2. 7367 - 56k trigger 6, D1 @ 1/4 A-pol, others off 7368 - 59k trigger 6, FS @ 1/4 B-pol, D5 off 7369 - 47k trigger 6, same setting 7370 - 6k trigger 6, same setting 7371 - pedestal run 7372 - TPC pedestal run 7373 - DVM run In the course of run 7366-7370 a total of 17.7k trigger 3 events were recorded with D5 off. Another 2.3k trigger 3 needed for goal at 20k. 3. The 4 suspicious top channels of H2 mentioned previously have currently demand voltage of -1400V. This gives read-back varying between -1575V and -1625V, although we could not see any periodicity in these variations. Tried to look at differences in ADC gains for previous runs, but interpretation is hard as also the good channels vary in similar manner as the bad ones. Some more testing should be performed on the power supply during access Wednesday. Horizontal fibers in FS were turned on this morning at 08:15. They have been off until now, but were sadly missed in Copenhagen. TPM1 still with anodes at 1160V until further notice. T3 still off. ------------------------------------------------------------
