------------------------------------------------------------ Date: Sat Feb 1 07:45:04 2003, Shift: 00:00-08:00 Supervisor: PS, with: Log book#13 pages 135 - 136 Shift Summary: ------------------------------------------------------------ 1. 3 stores during this shift - the last one is still lasting. Two first stores had ~30x10^11 ions in blue and ~60x10^9 ions in yellow ring. The collision (ZDC) rate was ~4k with low background, but in both cases beam was lost after about 30 minutes. Third store had ~30x10^11 ions in blue and ~30x10^9 ions in yellow with initial collision rate of 2k. 2.Only data runs: 7716 and 7717 MRS:6B, FS:1/15A 7718 and 7719 MRS:6A, FS:1/15A DAQ lost connection with fb3 (at 22:48 31Jan). Coudn't fix it, so decided to run without DCs (painful decision) and set FS field to 1/15. 3. NO CONNECTION WITH FB3. EXPERT NEEDED. ------------------------------------------------------------
