Benedetto Gorini (CERN)07/02/2012, 08:30The talk discusses the input from the experiments that is relevant to define next year's program. It covers the target for integrated luminosity for 2012, for both p-p and Heavy Ion physics, the configuration for the Heavy Ion period (p-Pb, Pb-Pb or both) and the requests for special runs (high beta, VdM scan with un-squeezed beam, high or low pile-up runs…). The impact of LHC parameters and...Go to contribution page

Stefano Redaelli (CERN)07/02/2012, 09:00An efficient turnaround will be an important parameter for the integrated luminosity performance at LHC in 2012, when an operation with steady beam parameters will be achieved at the beginning early on in the run. Improvements of the operational cycle were already put successfully in place after the 2010 experience but additional improvements are possible. In this paper, the 2011 turnaround...Go to contribution page

Rende Steerenberg (CERN)07/02/2012, 09:30At the start of the 2011 physics run quite some margins in the performance of the injectors were available and identified. Following the fast increase of the performance of the LHC itself during 2011, these margins have very much been exploited and some have even been pushed further. In view of further increase in the LHC luminosity, the 2012 performance reach of the injectors will be...Go to contribution page

Philippe Baudrenghien (CERN)07/02/2012, 10:30The improvements done to the RF parameters and hardware in 2011 are reviewed. We then present the upgrades planned for 2012: Further reduction of capture losses with the longitudinal damper, batch per batch blow-up at injection and modification of the blow-up to preserve bunch profile. Operation at higher energy is readily possible with the present RF power, and does not degrade longitudinal...Go to contribution page

Wolfgang Hofle (CERN)07/02/2012, 11:00Plans for the operation of the transverse damper in 2012 at bunch spacings of 50 ns and 25 ns and at increased collision energy will be reviewed. The increased energy and the experience that will be gained at 25 ns are very important to define any upgrades that may be necessary for the high luminosity operation at 7 TeV after LS1. This means that the available parameter space must be probed in...Go to contribution page

Markus Brugger (CERN)07/02/2012, 11:302011 very successful LHC operation has provided valuable input for the detailed analysis of radiation levels and radiation induced equipment failures. Radiation levels around LHC critical areas and the LHC tunnel were studied in detail and compared to available simulation results, as well as put in perspective to LHC operation parameters. Observed radiation induced failures were not only...Go to contribution page
