Upgrade of the BM@N detector for studies of heavy ion interactions

Abstract

In the next years the Baryonic Matter at Nuclotron (BM@N) experiment at Joint Institute for Nuclear Research (JINR) will carry out the physics program with heavy ion beams with energies up to 3.9 AGeV and intensities up to 2 [Formula: see text] ions/s. The experiment is devoted to measure observables sensitive to the equation of state of dense baryonic matter. To meet this goal the existing BM@N set-up will be upgraded with fast hybrid tracking system, which includes beam tracking detectors, a large aperture silicon tracking system, gas electron multiplier stations and cathode strip chambers. The measurement of the event plane and centrality will be achieved with a forward hadron calorimeter and granular hodoscopes. The physics program and configuration of the upgraded BM@N set-up are presented.
