 March 3-7  Have fragments of sections 1, 2, 3  Missing sections 4, 5, 6, 7, 8, 9  Very few figures  March expect parts of all sections, draft figures  Urgent!  March TP contacts work on improving readability  March Fabrizio-organized internal review  24 th Release draft to muon IB (reading group?)  28 th Have a muon IB reading  NB presentation to USG on longevity R&D plans, Mar. 17? 3

General Muon Meeting, 03-March-2014 Jay Hauser “Update on Phase 2 muon Technical Proposal”  DT: is MTT part of the baseline plan?  Currently not. Needs specific motivation from simulation, and/or approximate cost estimate as “option”.  RPC:  Is multi-gap for fine time resolution the baseline (sim. results)? Or else, approximate additional cost estimate for R&D and production. (Back-end and front-end electronics)  CSC:  Need backup plan in case trigger group decides 10  s not enough latency  GEM:  ME0 need to decide on baseline segmentation, “stack”  What else? 4

DT minicrate  Common plans: typically late-2014 to 2017  Detector and electronics radiation tests at GIF++ (all three subdetectors plan tests with source and beam)  Neutron and/or proton beams for electronics single event upsets  DT specific plans:  Replacement of the minicrates and upstream electronics, design  CSC specific plans:  CFEB rate capabilities at various latencies – verify expectations with data  RPC specific plans:  R&D on freon-less gas mixtures (LHC- and CERN-wide project) includes tests at GIF++ RPC chambers for GIF test 6

General Muon Meeting, 03-March-2014 Jay Hauser “Update on Phase 2 muon Technical Proposal”  GEM detectors (proposed for GE1/1, GE2/1, and ME 0  Chambers: well-advanced in context of GE1/1  5 th generation prototypes, assembly techniques optimized  GE2/1 very similar to GE1/1 but 2x larger, ME0 similar but more layers to cope with high-  rates; further industrialization, QC, and other studies ongoing  Front-end electronics: VFAT3 needed for CMS and under design  Back-end, DAQ, and trigger electronics R&D: under development for 40 o GE1/1 slice test installed in YETS 2016  Improved RPC detectors  Glass: 6 chambers to be tested at GIF++  High rate capability and time resolution to be studied  Bakelite:  Lower resistivity, new FE electronics for lower HV, gain being developed (CMS-ATLAS-ALICE) during  Muon Fast Track Tag (MTT) for barrel  Fast scintillator tiles read out with SiPMs and combined with DT/RPC in L1 trigger  Study ghost suppression, efficiency and timing in HO , develop prototypes GE1/1 slice test YETS 2016 VFAT3 New RPC electronics 7

General Muon Meeting, 03-March-2014 Jay Hauser “Update on Phase 2 muon Technical Proposal”  Geometry of new detectors mostly complete:  Have all new detectors implemented  ME 0 geometry will need refinement  Reconstruction implementation:  Rechits in all new detectors  Local reconstruction in all detectors  Global reconstruction in GE1/1 and GE2/1  Additional capabilities under development  Effect on trigger and muon ID:  Studies well advanced for GE1/1 (e.g. lower right plot)  Preliminary studies for other stations, e.g. ME 0 motivation for high-  muon tagging  Background rate estimation:  Existing detectors: comparisons of measured versus originally foreseen rates:  For 1/1, 2/1, 3/1, and 4/1 will allow straightforward estimation (only variable is sensitivity of detectors)  Ongoing studies: various complicating effects such as neutron leaks (CSC station 2), TOTEM, CASTOR  For ME 0, optimization of shielding etc. needed  Depends on calorimeter detailed configuration ECFA 2013 GE1/1 GE2/1 ME 0 GEM-CSC trigger combination 8
