High Intensity neutron generator (HINEG)is an accelerator-based D-T fusion neutron source with both steady and pulse neutrons.The general layout and main design features of HINEG were analyzed in the paper.The design index of steady neutron source strength is reaching 3 × 1013 n/s and which of the full width at half maximum (FWHM)for pulse neutrons is less than 1.5 nanoseconds.The results of beam optics calculation confirmed that design index was reached.Main technical features of HINEG layout are D+ selection by solenoid lens,uniform field accelerating tube with high gradient and chopping at high energy.
