Design study of high intensity D-T fusion neutron generator HINEG

The R&D of HINEG (High Intensity D-T Fusion Neutron Generator) includes two phases: HINEG-I and HINEG-II. HINEG-I is designed to generate both the steady beam and pulsed beam, and have successfully produced a D-T fusion neutron yield of up to 1.1 × 10¹² n/s. HINEG-II aims at a high neutron yield of 10¹⁴∼10¹⁵ n/s neutrons via high speed rotating tritium target system and high intensity ion source. HINEG can be used for research of nuclear technology and safety including the validation of neutronics method and software, radiation shielding and protection, mechanism of materials activation and radiation damage as well as neutronics performance of components. Its application can also be extended to nuclear medicine, radiotherapy, neutron imaging and other nuclear technology applications. This paper introduces the scenario of design and progress in R&D of key technology of HINEG. (authors)
