Key Points

  • The research aims to investigate the characteristics of a detection setup for studying nuclear reactions involving light nuclei.
  • Developed a position-sensitive neutron detector with 10B nucleus for detecting nuclear interactions.
  • Implemented a proportional chamber sized 50 × 50 mm2 for improved measurement precision.
  • Utilized silicon and NaI scintillation detectors in an electron-positron pair spectrometer.
  • Demonstrated capability to select various nuclear reactions involving light nuclei such as 3H and 4He.
  • Confirmed that the setup operates effectively with fast neutron sources with energies exceeding 1 MeV.

Abstract

In this paper, we study the characteristics of a setup that contains a position-sensitive neutron detector with the 10B nucleus under study, a proportional chamber with dimensions 50 × 50 mm2 and an internal conversion electron-positron pair spectrometer based on silicon and NaI scintillation detectors. This setup will be used for studying reactions with light nuclei on fast neutron sources with energies above 1 MeV based on linear electron and proton accelerators at INR RAS. The possibility of selecting various reactions with the emission of a light nucleus, in particular 3H and 4He, has been demonstrated.
