  • In this paper a newly developed medium-type pulsed fast neutron detector is proposed. The detector consists of front insulator,n-p converter,absorber,collector and rear insulator. The detection principle is based on the output signal from both recoil-protons of the n-p converter and secondary electrons induced by the recoil protons passing the interface between the absorber and the collector. Because of its detection of fast neutrons in the medium,unlike many trandifional fast neutron detectors which work in the vacuum environment,this detector has obvious advantages. It does not need vacuum environment and high voltage power supply. This makes it to be used easily. By choosing teflon as the absorber and by choosing graphite as the charge collector,the contribution of the secondary electrons to the output signal can be determined experimentally.

Abstract: In this paper a newly developed medium-type pulsed fast neutron detector is proposed. The detector consists of front insulator,n-p converter,absorber,collector and rear insulator. The detection principle is based on the output signal from both recoil-protons of the n-p converter and secondary electrons induced by the recoil protons passing the interface between the absorber and the collector. Because of its detection of fast neutrons in the medium,unlike many trandifional fast neutron detectors which work in the vacuum environment,this detector has obvious advantages. It does not need vacuum environment and high voltage power supply. This makes it to be used easily. By choosing teflon as the absorber and by choosing graphite as the charge collector,the contribution of the secondary electrons to the output signal can be determined experimentally.
