Bernhard Holzer, Joerg Wenninger Thursday Morning 31-Jan 2013 Bernhard Holzer, Joerg Wenninger Wednesday Morning ... LHC in access for temperature alarm (“RF faraday cage”, ventilation problem) ... after a lengthy discussion ... decide to refill the source Plan for LHC: ADT set up for the future quench tests 10:00h injection delayed ... POPS 11:30h injection for ADT tests (protons in beam2)

LHC STATUS Wednesday Late ≈ 16:00h source ready, Pb available BUT 16:30h Water fault on demineralised water in S23 / S34 loosing 100 m3 / day ... which will run into trouble during the weekend 19:00h Water leak found on pipe connected to RB in S34. 20:10h Expert working on Beam Imminent Warning system ... which is still not operational in Pt 7/8 ... to be fixed today !! 04:30h ... 21:00h ... in parallel: since early morning intermittent problem at RF: (problem disappeared at 05:30) faulty VME modules in the Tuner Controller for cavities 5,6,7 and 8 B1. 22:00h Precycle 22:30h Collimator error network problem ? 29/06/2012 LHC 8:30 meeting

LHC Status Wednesday Night 00:00h injection probe beam 00:30h injection physics beam some optimisation needed ... TL steering, RF phase 00:50h beam dump: false trigger from BLM in point 1 (no losses observed) ->MKD beam 2 in error after the beam dump “fault on LBDS kicker was "retrigger box1 compensator B" on generator” 01:15h ... 02:00h injection & TL optimisation 02:10h machine full, prepare ramp 60o inj phase 29/06/2012 LHC 8:30 meeting

LHC Status Wednesday Night 02:55h adjust & lumi optimisation 03:00h stable beams 03:04h separating IP1 and 5 by 130 um in separation plane 5 % 9 % 29/06/2012 LHC 8:30 meeting

LHC Status Wednesday Night 03:10h ... optimisation of lumi & lifetime for beam 2 trim Total voltage to 14MV for B2 orbit correction h & v tune optimisation τ ≈ 8.5h 29/06/2012 LHC 8:30 meeting
