------------------------------------------------------------ Date: Thu Sep 20 08:28:08 2001, Shift: 00:00-08:00 Supervisor: J.I.Jordre, with: NN Log book#9 pages 13 - 14 Shift Summary: ------------------------------------------------------------ 1. Beam most of the shift. Only about 1 hour interruption to fill RHIC from 03:53 to 04:55. However, still only about 50% of the ZDC rates of the other experiments. Called MCR twice asking for steering, but no increased rates. 2. Run 4817 (started last shift) with 346k trigger 1 events Run 4818 with 63k trigger 1 events Run 4822 with 254k trigger 1 events Run 4823 (still running) with 80k trigger 1 events => Now beyond 1M trigger 1 events at current magnet settings. Should therefore change FS to 4kG B polarity at the end of this store. 3. YK tinkered with the ZDC low gain ADC Blue Right module 1 cable in the FEH, i.e. unplugging and replugging the cable. That solved the problem reported in last evening shift. T5 anode 1 and all anodes in T3 tripped once, without particularly high currents. Voltages brought back up to nominal values without any problem. ------------------------------------------------------------
