Shift summaries for Evening March 12, 2000 and Owl March 13, 2000 Shiftees: a cast of thousands...hundreds...tens!!! 00/03/12 16:00 Stop stacking with 9.2mA Much work to re-establish accumulator systems which have been off for a month (RF and cooling). 19:00 Start Jet Target at nominal 0.6x10^14 density. Confirm H2OR is working and set jet density at 1.3x10^14 where the calculated density (from read back values) is stable to 5%. Setup and perform Vertical beam scan of jet target. Confirmed that maximum H2OR rate is if beam is bumped 1.25mm upward. 21:30 Setup and perform Horizontal beam-jet target scan of luminosity monitor hole. Method is to take 10 minute run at each horizontal bump setting (steps ~1mm) calculate (L-R)/(L+R) where the Left and Right fixed luminosity monitor detectors are used. (Runs 5207-5214) 'Map' out ~4mm range where ratio is consistent; at one extreme, see ratio of 0.7. Nominal orbit is in the center of where ratio is 0. 00/03/13 00:30 Work on/look at counters, straws, scifi, charged trigger logic signals. Gain changed in FH5,FH7,HP14 to have same signal amplitude as other counters; HP19 is fine. Straw thresholds are increased for outer chamber Check signals using online monitor(s) 02:30 Run 5218 wrote tape of GM2 (2h,H2=2,COPL) and GM12 (min bias) to check straw thresholds, T_0 and charged trigger logic effiencies. Run 5219 wrote tape of GM2 for another special run for straws with different thresholds. 04:15 Run 5220 special run to check min bias timing signals by turning on every 8th CCAL counter in the HV file; cycle through eight sets of 1/8 of the CCAL on. Run 5223 another special run using the old CCAL (1/8 of the wedges on) HV files since want every 8th wedge and not 8th counter as organized in the HV file. 06:30 Gas jet is exercised along new Pressure-Temperature path where T is always 2K more than the saturation curve for the corresponding P. Mapping out the density as a function of P and T along curve.
