The CBM muon detection system (MuCh) was optimized for nucleus-nucleus collisions at SIS300 beam energies (see [1]). We have investigated the possibility to simplify the setup for measurements of J/ψ mesons in proton-nucleus collisions at SIS100 beam energies. Therefore, the performance of the muon detection system has been studied as function of the number(More)
The CBM muon detection system is designed to measure muon pairs from the decay of vector mesons (ρ, ω, φ, J/ψ) produced in heavy-ion collisions. At FAIR energies the muon momenta can be rather low, and, therefore, we developed a muon detection concept which a dynamical definition of absorber thickness according to the muon momentum. The actual design of the(More)
The layout of the CBM muon detection system has been improved and optimized in 2007 with respect to background suppression and a more realistic detector response. The modifications include: • compact absorber system in order to reduce the number of muons from weak pion decays; • realistic detector segmentation according to an occupancy of 5%; • additional(More)
The CBM experiment at FAIR will measure the leptonic decay of vector mesons both in the di-electron and the di-muon channel. A particular challenge is the identification of the soft muons from ρ, ω, and φ mesons produced in nucleus-nucleus collisions at beam energies between 15 and 45 AGeV. To perform these measurements an instru-mented hadron absorber(More)
The CBM muon detection system is designed to measure muon pairs from the decay of vector mesons (ρ, ω, φ, J/ψ) produced in heavy-ion collisions. At FAIR energies the muon momenta can be rather low, therefore, we developed a muon detection concept which a variable definition of absorber thickness according to the muon momentum was been developed.
