Presentation Transcript

  1. 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 LHC status

  2. 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 LHC status

  3. aperture IR8 LHC status

  4. Example LHC status

  5. 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 LHC status
