description: The subject of the graduate qualification work is âDevelopment of a system of scintillation detectors for space radiation suppression in the experiment aims to study dd-fusion reactions with the low beam energy (PolFusion)â. This work is devoted to the process of creating a system of scintillation detectors for suppression influence of space radiation background. This work was carried out as part of the PolFusion nuclear physics experiment carried out at the Petersburg Nuclear Physics Institute (Gatchina). The purpose of that experiment is to study the fusion reaction of 2H (d, p) 3H and 2H (d, n) 3He with polarization of the initial particles at low energies in the range of 10-100 keV. Tasks that were solved in the development process: 1. Simulation of the central detector system of the PolFu experiment. 2. Development of the design and fastenings of the system of scintillation detectors. 3. Simulation of a system of scintillation detectors. 4. Monte-Carlo simulation of the joint operation of systems and testing of the anticoincidence algorithm. 5. Assembly process of the test system. As a result, the optimal design of the system, the detector material, and the type of photomultiplier were chosen. The effectiveness of the developed system was evaluated, and cosmic radiation was registered using a test assembly.
