CMS Phase-2 Muon upgrade

Figure Caption

Sketch of the proposed upgrade for the CMS muon system in the forward region for Phase-2. New detector technology based on Gas Electron Multipliers (in red) could potentially enhance the CMS capabilities on muon reconstruction and triggering in the HL-LHC environment if the backgrounds are under control.

ME1/1 particle fluence comparison v.1.0.0.0 vs v.2.0.0.0

ME0_CMSpp_v2.0.0.03.png

Monte Carlo estimation of the particle fluence using FLUKA simulation. Primary proton-proton collisions with an energy of 7TeV per beam. Inelastic collision cross section used for normalization is 80 mb. Used simulation cut offs: Hadrons 1 keV, Neutrons 0.01 meV, Photons 3 keV, Electrons 30 keV. Photons and Electrons have significantly higher cut-offs in some regions (heavy parts). The plot shows the particle fluence as a function of the CMS radial coordinate assuming an instantaneous luminosity of 5.10^34cm-2s-1. The scoring region is the ME1/1 volume and the plot shows a comparison between geometry v.1.0.0.0 and v.2.0.0.0

RE1 background hit rate: comparison simulation vs data

Comparison of Monte Carlo particle fluence vs RE1 data. The data was collected during 2011 campaign using 3.5 TeV per beam energy. Simulation is scaled to a luminosity of 5.10^{33}cm-2s-1. The Monte Carlo was combined assuming contribution of neutrons, photons, electrons and positrons, fluxes were combined with the detector sensitivity for each particle.
