Preliminary Study on Accelerator Based D-D Neutron Generator with Hydrocarbon Liquid Target

This study suggests new concept of the D-D neutron generator which can achieve the high neutron yield and energy without tritium. The highly accelerated beam up to 10 MeV will enhance not only the total neutron yield but also the forward yield and the neutron energy. Also, the hydrocarbon liquid target is expected to reduce the required beam current by its low energy loss rate, and treat the high energy beam by the self-cooling and healing function. A neutron generator is very usefully utilized in various field such as neutron activation analysis, neutron radiography, and medical application. Especially, a fast neutron generator based on beam-target fusion reactions is favored at a laboratory level. Because the neutron generator has advantages such as a compact size, flexibility of operation and low establishment cost, in contrast to a research reactor. In addition, the higher neutron energy than the research reactor allows a reaction whose threshold energy is higher than 2 MeV. Thus, more elements can be utilized in a neutron activation analysis. Also, a low specific activity of isotope production by (n, γ) reaction can be improved when (n, p) reaction is utilized
