Influence of the high granularity calorimeter stainless steel absorbers onto the Compact Muon Solenoid inner magnetic field

Abstract

Article highlights The method of the magnetic field double integrals to investigate a quality of the magnetic field in the particle detector is fully described. The possible perturbation of the magnetic field inside the Compact Muon Solenoid inner tracker with the replacement of the endcap hadronic calorimeter is investigated. The estimations on the degradation of the charged particle momentum resolution are presented.
