Presentation Transcript

  • Several presentations on e-cloud status in LHC

    • LMC 18/09/2013: overview, present status of understanding

    • LBOC 08/10/2013: heat loads in cold magnets and extrapolation to future operation (post-LS1): encouraged effort to make heat load and bunch-by-bunch stable phase monitoring on line for 25 ns run

    • RLIUP Preparation meeting 15/10/2013: overview and extrapolation of heat load values to future operation (post-LS1, PICs, US1, US2) for different scenarios

    • In general, strong endorsement to plan using doublets in LHC after LS1 to try suppressing the e-cloud in the dipoles (will be followed up within the LBOC, already scheduled on 5 November 2013)

  • HL-LHC Triplets

    • WP2 meeting 18/10/2013

      • Summary of understanding of the present triplets

      • Results for the new triplets  need to include in design electron cloud suppression measures (a-C coating and/or clearing electrodes)

  • E-cloud meeting #5

    • Octavio’s rehearsal of PhD defense (mainly LHC results from SS, scrubbing optimization studies with maps, future accelerators)

    • Discussion on sensitivity of build up simulation on model parameters (when defining thresholds for different filling patterns)


  • SPS

    • Scrubbing strategy for 2014: Scrubbing run tentatively fixed on weeks 40 – 41. Decision for coating vs. scrubbing to be made by mid 2015 (detailed strategy will be discussed by Hannes in RLIUP)

    • Coating planning for LS2: logistics sorted out (building for coating lab, transportation from the tunnel, production rate, etc.), it should be possible to coat 90% of the SPS within 12 months
