Abstract: This document describes the technical layout and the performance of the Muon Chamber (MuCh) System of the Compressed Baryonic Matter (CBM) experiment at FAIR. The MuCh system is designed to identify muon pairs which are produced in high-energy heavy-ion collisions in the beam energy range from 4 to 40 AGeV. The measurement of lepton pairs is a central part of the CBM research program, as they are very sensitive diagnostic probes of the conditions inside the fireball. At low invariant masses, dileptons provide information on the in-medium modification of vector mesons which is a promising observable for the restoration of chiral symmetry. At intermediate invariant masses, the dilepton spectrum is dominated by thermal radiation from the fireball reflecting its temperature. At invariant masses around 3 GeV/c2, dileptons are the appropriate tool to study the anomalous charmonium suppression in the deconfined phase. In the CBM experiment both electrons and muons will be measured in order to obtain a consistent and comprehensive picture of the dilepton physics.
