CMS FLUKA geometry v.2.0.2.0

Figure	Caption
CMS_FLUKA_geom_v2020	CMS FLUKA geometry v.2.0.2.0 represents the configuration of one of the proposed phase II endcap upgrades. It is based on v.2.0.0.0, the most up-to-date FLUKA model of the Run 2 situation. This includes a representation of the upgraded central beampipe, and the YE4, as well as various improvements in the FLUKA model to the muon chamber shielding. In v.2.0.2.0, 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). The image shows a zoom into the CMS forward region where the end-cap calorimeters and the CSCs ME1/1 and ME2/1 muon stations can be identified. The volume where the new GEM detectors (ME0,GE11,GE21) will be installed is currently filled with air to allow for the computation of the radiation environment.

GE11_FLUX_v2021	Monte Carlo estimation of the particle flux at CMS using FLUKA version 2011.1b.6. 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 FLUKA model to 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 flux as a function of the CMS radial coordinate (R) covering the proposed location for GE1/1, assuming an instantaneous luminosity of 5x10^34cm-2s-1.
