Development of a High Granular TOF Neutron Detector for the BM@N Experiment
This article describes the design of the HGND detector (High Granular Neutron Detector) for measuring azimuthal neutron fluxes in the range from 300 to 4000 MeV as well as heavy ions formed in nucleus-nucleus collisions at energies up to 4 AGeV in the BM@N (Baryonic Matter at Nuclotron) experiment on the extracted beam of the JINR Nuclotron, Dubna. The detector consists of 16 layers of plastic scintillation detectors having a cellular structure with copper absorption plates between the layers. The results of measuring the time resolution of scintillation cells using silicon photodetectors are presented. The proposed electronics circuit for reading signals from scintillation cells is described. The results of modeling the acceptance of a neutron detector, the efficiency of neutron detection, the neutron energy resolution, and an estimate of the neutron count rates for the Bi + Bi reaction at an energy of 3 AGeV are presented.
