High Intensity D-T Fusion Neutron Generator (HINEG), developed and constructed by the Institute of Nuclear Energy Safety Technology, Chinese Academy of Sciences · FDS Team, produced D-T fusion neutrons with yield of up to 1.1×1012n/s in the experimental operation on Jan. 2nd, 2016, marking the accomplishment of Phase I. The high intensity accelerator and high power rotating target systems operates stably.

Focusing on neutronics theory and efficient utilization of neutrons in advanced nuclear systems, FDS team has made lots of academic achievements and has founded the Key Laboratory of Neutronics and Radiation Safety, Chinese Academy of Sciences. And aiming at further research on experimental validation of neutronics theoretical models and relevant nuclear technology experiments, the team initiated HINEG program with supports from more than 20 leading international institutes. In the past six years, they have made several breakthroughs in key technical issues of intense deuterium ion beam transport, high power dissipation as well as integrated measurement and control and so on.

In addition, the team has developed more than ten sub-systems and hundreds of key devices, such as the ultrahigh voltage DC switching power supply, high intensity ion injection system, high voltage and high intensity accelerating tube, high power rotating target and high intensity neutron experimental system. Particularly, the high power rotating target tackled the intense cooling issue under high intensity beam bombardment and the temperature in the target spot was suppressed to less than 200 oC under 10 kW/cm2 thermal loading.

Neutron is the key element for the nuclear system operation and safety assessment. Thus the neutron source is well recognized as an essential experimental platform for the development of nuclear energy and nuclear safety technology. HINEG accelerates deuterium ions to bombard tritium target for producing 14.1 MeV fusion neutrons, which can be directly used in representing the neutron environment in future fusion reactors. Moreover, HINEG is available for fusion technology related researches including energy science and technology experiments on tritium breeding, energy generation, material activation/damage, radiation protection. Furthermore, the moderated neutron can be used in simulating neutron environment of current fission reactors and other advanced fission reactors for nuclear safety experimental research.

Besides, the application of HINEG neutron source can also be extended to nuclear medicine and radiation treatment, nuclear logging and ore exploitation, isotope production, neutron imaging and other fields, which benefits the relevant high-technology industries.
