------------------------------------------------------------ Date: Mon May 12 15:27:45 2003, Shift: 08:00-16:00 Supervisor: fv, with: Log book#14 pages 108 - 108 Shift Summary: ------------------------------------------------------------ 1) Beam development restoring polarization which succeeded. Beam available from ~ 12.15 albeit only in physics mode much later. The big boys voted for dumping - dumped at 15:15 2) Tdc calibration run 8919 Decided to call 1/2A 12 deg for complete 3.8 K trigger 2. After the 4 deg high filed and pol running 12 deg can be cobntinued at 2/3 field to optimize pt ~3 GeV/c. Data run 8925,8926,8927 100K trigger 6 12 deg at 1/15 field. zero filed run 8928 (2 k trigger 6) needs more. Worked to implement more (last) input to spin scalers with Brendan Fox. (ZDC gates narrow+ Background Blue,yellow) 3) No new problem - attempted to dix some bad tofw and tfw2 slats see e-log for details. A: we now attempt to start and stop the spin scalers on a routine basis i.e. RSstart.perl before run and RSstop.perl after run. Store hours took data from 12:30 to 15:15 == 2.75 hours ------------------------------------------------------------
