Description

The fixed-target experiment BM@N is designed and constructed to conduct studies of nucleus - nucleus collisions with beams of Nuclotron at energies of 2 – 4 GeV per nucleon. The developed interaction trigger is based on a system of fast scintillation beam counters and barrel multiplicity detector. A special electronics module was developed using FPGA technology for realization of trigger logic with minimal delay. Beam counters have a picosecond time resolution and provide start pulse for time-of-flight detectors of the BM@N experiment. Hear we give an overview of the trigger detectors and electronics, and report on system performance in experimental runs with Xe ion beams.
