------------------------------------------------------------ Date: Wed Jul 5 00:43:00 2000, Shift: 16:00-24:00 Supervisor: ko, with: ma, rami, zis Log book#2 pages 134 - 135 Shift Summary: ------------------------------------------------------------ 1. Machine was sick all shift, going through the cycle: - inject (intensity as high as 2500+2500 in both beams) - start ramp - immediately loose one beam - loose the second beam at transition - ramp down, - repeat every 30-40 minutes. 2. Fire alarm in our area (1002B). Had a visitation by firemen (2 fire trucks + 3 aux cars), BNL police, HP and MCR. Firemen went into tunnel towards the 1003 area, did not find any fire, alarm cleared itself. I do not think firemen (with big axes, etc) went into the 1002 IR. Conclusion: false alarm. Current machine status: resweeping tunnel (sweep lost by firemen), also yellow quench link interlock. Further beam highly unlikely, experiment was shutdown (TPC high-voltages are off, BB, Tiles, H1/H2, etc... hv left on, magnets are off), everybody goes home and there is no 24-to-08 shift. 3. No known detector problems. K.O. ------------------------------------------------------------
