HINEG (High Intensity Neutron Generator) neutron generator is being designed and built DC / pulse dual-purpose high-flow deuterium tritium fusion neutron generation device. This article gives the overall plan of the device, and analyzes its main design features. The maximum design index of HINEG DC neutron intensity is 3 × 1013 n / s, the design index of pulse neutron pulse width is less than 1.5ns, and the beam optics calculation results show that the overall scheme design can meet the design requirements. Key features of the system design include beam focusing of the solenoid lens, pulsed mode of high-gradient uniform field acceleration and high-energy segment cutting.
