Abstract
The algorithm for track reconstruction in multiwire proportional chambers (MWPCs) of the BM@N (Baryonic Matter at Nuclotron) experiment is described. The beam tracks before the interaction with the target and trajectories of charged particles after the interaction are reconstructed using Nuclotron experimental data with deuteron and carbon beams colliding with the carbon and copper targets. Trajectories are extrapolated to the interaction point and to drift chambers. The efficiencies of MWPCs have been obtained. Beam parameters (transverse dimensions and angular spread) have been measured as well.
