------------------------------------------------------------ Date: Wed Sep 19 08:22:16 2001, Shift: 00:00-08:00 Supervisor: J.I.Jordre, with: none Log book#9 pages 7 - 8 Shift Summary: ------------------------------------------------------------ 1. MCR unable to clear blue quench link interloch that occurred before midnight. Experts were called for and they fixed the faulty "quench protection assembly interface chassis". Beam since 05:40. Dana went to MCR to ask them to steer the beam in BRAHMS IR, as our ZDC rates were about half the rates of STAR and PHENIX. MCR tried to steer for about 30 mins but were not able to increase our ZDC rates. 2. Run 4808 with 86.3 trigger 1 events. About 1/3 of these have T3 & T5 anode 1 off as I did not detect the trip untill 15 mins. after it occured. Run 4809 still running. 3. T3 & T5 anode 1 tripped once, about the same time. Voltages remounted without problems. ------------------------------------------------------------
