------------------------------------------------------------ Date: Sat Oct 20 00:31:37 2001, Shift: 16:00-24:00 Supervisor: J.I.Jordre, with: Log book#10 pages 36 - 37 Shift Summary: ------------------------------------------------------------ 1. Beam from 17:48 to 18:39, when beam was lost because of blue quenc link interlock. Then problems with cryo Turbo expansion pump, trying to swith to backup pump, and finally reporting that there had been some oil leak in the pump so that the estimate is there will be no beam for at least 12 hours. I.e. probably no beam untill Saturday at 12 noon. If someone needs access to the IR, call MCR and they will go to restricted access. 2. Run 5446 12k trigger 6, ended when I found BBL 37 had tripped Run 5447 32k trigger 6. TPC pedestal, DVM and pedestal runs 5448, 5449 and 5450 respectively. 3. Only the mentioned trip of BBL 37. Turned down magnet currents and put them into stand-by mode before closing business. ------------------------------------------------------------
