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. vs v.

Figure Caption


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. and v.

RE1 background hit rate: comparison simulation vs data

Figure Caption


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.
