Presentation Transcript

  1. ECFA Muon talk2 Longevity and Expected Performance of the Existing Muon System at the LHC Experiments C. Bedoya, P. Dupieux, P. Iengo, G. Lanfranchi

  2. Present muon detectors and performance ~4 slides ~2 slides • Short intro on the 4 systemswith main performance resultsafter Run1 • Consolidation during LS1 (ATLAS, CMS)

  3. Present muon detectors and performance

  4. Challenge with HL-LHC operation ~3-4slides • Common aspects on muon detector limitations with HL • Occupancy • Rate capability • Dead time • Fake trigger rate • Ageing LHCb

  5. Expected performance and upgrade plans ~4-5 slides • What are the expected performances (lifetime) of the systems and how the experimentswillcopewith the higherluminosity scenario (Phase1 and Phase2) • Specific issues for each system • Specific tests to beperformed to establish if the present detectors fulfil the requirements of HL-LHC and spot weakness/marginalities • Upgrade plans (stressing the impact on the system performance, w/o describing the technologies ) Status of the presentation • ALICE:received a summaryslide. No muon upgrade foreseen, but more material on the future performance of the current detectors isneeded • ATLAS: all material ~in hand. Phase1 OK, to bedecidedwhat to include for Phase2. • CMS: receiveddetailedslides, all material in hand. Someiterationneeded in the followingweeks • LHCb: No materialreceivedso far. No upgrade foreseen for the muon system, material for the present detector (and the future performance) neededanyhow.
