    1. 5. QPS - analysis of main problems, areas to target, possible improvements
      Reiner Denz
      12/12/2011, 14:00
      The fault statistics of the LHC Quench Protection System QPS for the LHC run 2011 will be presented and the various fault types explained. Starting with teething and EMC related problems, the tune feedback compatibility, hardware faults of the quench heater power supplies and spurious openings of electrical circuit breakers will be described in more details. Hereby as well the necessary and...

      12/12/2011, 14:25
      After recalling the methodology in place, the statistics for LHC cryogenics will be presented for 2011, with analysis of the various origins and overall comparison with 2010. Beam parameters and their effects on operation will be described. Radiation induced effects will be described together with implemented or planned actions, as well as other major actions foreseen for the Xmas break....

      12/12/2011, 14:50
      As any other accelerator LHC has to undertake period of stop for maintenance. Five technical stops have been performed during 2011 run and a quite long recovery time has been sometimes experienced. An analysis of the reasons is presented with particular attention to the interventions carried out during the stop. An outlook on the future is also considered to try to increase the LHC...

      12/12/2011, 15:15
      2011 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...
