Yesterday Power back around lunchtime Access until 12:30 Totem winkled out last QPS tests on sector 12 Pre-cycling interruptus by re-energization of SVCs around the ring Access (6 & 4) again for beam dump in the shadow 20:15 Pre-cycle again 22:15 Beam circulating again 02-12-09 LHC status

Overnight Aperture checks in IR8 Loss cyro instrumentation ROFA45.B2 temperature monitoring – masked, to be superlocked force cryo start cryo maintain Beating team started, finished at 8:15 Collimators in coarse, BLMs in 3 & 7 unmasked Number of problems with LBDS sync problem with BETS XPOC failure IPOC – retriggering LBDS be woken up all night similar problems this morning 02-12-09 LHC status

aperture IR8 02-12-09 LHC status

Example 02-12-09 LHC status

Beating Beta-beating experiment finished for now... 1. Beam 1 has a positive effect from the corrections applied. 2. Need to understand IR7 results more carefully for Beam 2. All trims and tunes reset to initial settings. Off line analysis to follow Capture not used 02-12-09 LHC status
