EE and basic HE driving the calor. design, not tail catcher >9.5l Excellent simulation progress
See Cesare Calabria talk at today’s muon POG https://indico.cern.ch/event/305369/, “now we have a 2023 scenario that works with all the muon upgrades!”
TP contacts group has started assembling text for a 30-page draft
This week: LHCC upgrade presentation concentrating on R&D activities Three slides sent as input for Didier, see backup
Upgrades Week at Karlsruhe Mar. 31-Apr. 4 Have you registered? First draft of the TP to be prepared

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
ms not enough latency GEM:
ME0 need to decide on baseline segmentation, “stack”
What else?
Decisions to be made by Upgrades Week

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 2015-20 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++
Longevity R&D for existing muon detectors
RPC chambers for GIF test

GEM detectors (proposed for GE1/1, GE2/1, and ME0 Chambers: well-advanced in context of GE1/1
5th generation prototypes, assembly techniques optimized
GE2/1 very similar to GE1/1 but 2x larger, ME0 similar but more layers to cope with high-h 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 40o 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 2014-16
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 2014-16, develop prototypes 2014-20

Geometry of new detectors mostly complete: Have all new detectors implemented ME0 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. ME0
motivation for high-h 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 ME0, optimization of shielding etc. needed
Depends on calorimeter detailed configuration
