Abstract

Baryonic Matter at Nuclotron (BM@N) is a fixed target experiment at the NICA accelerator complex in JINR aimed to study nuclear matter in relativistic heavy ion collisions. Detectors based on Gas Electron Multipliers (GEM) are used for the central tracking system of the BM@N experiment, which is located inside the BM@N analyzing magnet. The structure of the GEM detectors and the results of study of their characteristics are presented. The performance of seven GEM detectors integrated into the BM@N experimental setup and data acquisition system is briefly reviewed.

Highlights

  • The study of nuclear matter properties under extreme conditions is one of the most rapidly developing areas of modern physics

  • The main goal of the experiment is to study the interactions of relativistic heavy ion beams with fixed targets

  • Since the magnetic field is perpendicular to the electric field direction in the Gas Electron Multipliers (GEM), electron avalanche in GEM gas gaps drifts at some angle with respect to the normal to the readout board (Fig. 2a)
