1. 19 March 2012Muon Week - Operations1 Muon Week Muon Operations Session Introduction Status and LHC Schedule Detector Readiness + Preparation for Physics Running –CSC, MDT, RPC, TGC Dedicated Runs, Weekly Operation, Planning etc. March 19 th 2012 A. Polini

2. 19 March 2012Muon Week - Operations2 Status 3 months shutdown just over Running since 2 weeks with 24/7 shifts Many activities performed on Detector, Infrastructure, HW + SW –MDT EE side C fully installed –RPC power, HV, gas, etc. –TGC chamber replacement + conditioning –MDT gas leaks and general overhaul –CSC Rod Firmware –… and many more  detailed reports afterwards Priority: Readiness for Highest Luminosity Running Good and Stable Data Taking Conditions 2

3. 19 March 2012Muon Week - Operations3 LHC Schedule Day LHC Tentative Planning: 1injection & closed orbit 3: ramp & squeeze probe 5: injection of nominal bunch at ref orbit (flat). 7start collimation setup at 450 GeV. 8aperture at 450 GeV. 12: setup first collisions 14ramp & squeeze with nominal bunch. 16: start collimation setup at 4 TeV 20: multi-bunch injection 23first stable beams 3x3.
