Sector layout of Muon Chambers (MUCH): first results

In the CBM experiment, muons have been identified as one of the potential candidates for the measurement of penetrating probes like low-mass vector mesons and charmonia. Extensive simulation studies has already established the feasibility of di-muon measurements. The present paper gives the first results of muon measurements for the sectored structure of the muon chambers. From the practical point of view a sector layout is much easier to implement compared to the modular detector design. It also helps to significantly decrease the pad multiplicity and thus reduce the cost
