Current compensation for material consumption of cobalt self-powered neutron detector

Nuclear Engineering and Technology, 2020
Co Self-Powered Neutron Detector (SPND) is confronted with the problem of material consumption, which causes the response current can neither reflect the change of neutron flux in time nor be proportional to the neutron flux.
