Evening Shift Summary 1/29/2000 Beam at start: 4.77 mA; Beam at end: 3.53 mA; Data type: Psi' scan (9th point) Runs 5036, 5038 Run 5042 CCAL timing into minimum bias stuff 1pe Cherenkov Summary: We finished Psi' scan at the 9th point. During the run 5036, G. Stancari reported that pbar momentum was changing. We stopped run 5036 when Werkema called to say the beam was stable. Run 5037 aborted with tape_drive #8 problem. Run 5038 started at 17:36 with 4.44 mA and finished at 21:05 with 3.77 mA. DAQ hanged frequently. After 1 hour we noted the VLPC HV were off. Wander swiched them on but the problem was not fixed.DAQ was reading TDC and ADC of the fibers but the online monitor plots showed nothing. We weren't able to solve the problem until the end of the run. At 19:40 the jet target nozzle got clogged: Stephen P. warmed it up and unclogged it.We then set the density at 2.3 x 10^14 cm-3. It has remained stable until the end of the run. At 21:15 data for timing of CCAL started. HV was set on 1 block/minbias sum only for all sums for all blocks in turn using Federica's famous files. Minbias thresholds were set to 500 mV (~200 MeV) and the discriminator which sets the number of minbias sums above threshold was set to 35 mV (1 set). IT WAS RESET TO 71 mV. At 00:05 we called main control room and they dumped the beam. At 1:30 1pe of the Cherenkov done. ON SHIFT: SS MO PR GUEST: SP KG FL NP
