ME0_hitrate_v2021_reb.png

Monte Carlo estimation of the particle HitRate (Flux weighted by detector sensitivity) at ME0 using FLUKA version 2011.1b.6 for particle flux and GEANT4 simulation for GEM sensitivity. The results are based on CMS FLUKA geometry v.2.0.2.1. CMS FLUKA geometry v.2.0.2.1 is based on v.2.0.2.0 which represents the configuration of one of the proposed phase II endcap upgrades. v.2.0.2.0 includes a representation of the upgraded central beampipe, and the YE4, as well as various improvements in the muon chamber shielding, the end-cap calorimeters are replaced with a preliminary model of the High Granularity Calorimeter (HGC) option and the HE rebuild (covering up to 3 in the pseudorapidity range). In v.2.0.2.1 additional shielding material is covering the volume where the ME0 detector will be installed using 3cm layers of B-polyethylene and 1cm layers of Lead-Antimony (sides and bottom) to further reduce the contribution of neutrons and photons. Primary proton-proton collisions with an energy of 7 TeV 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 HitRate as a function of the CMS radial coordinate (R) covering the proposed location for ME0, assuming an instantaneous luminosity of 5x10^34cm-2s-1 and the most recent estimations for GEM sensitivity to neutrons,photons,electrons and positrons.
