摘　　要：HINEG(High Intensity Neutron Generator)中子发生器是正在设计建造的直流/脉冲两用型强流氘氚聚变中子发生装置。本文给出装置的总体方案,并对其主要设计特点进行分析。HINEG直流中子强度的最高设计指标为3×1013 n/s,脉冲中子脉冲宽度的设计指标小于1.5ns,束流光学计算结果表明,总体方案设计可以满足设计指标要求。系统设计的主要特点包括螺线管透镜选束聚焦、高梯度均匀场加速管加速和高能段切割的脉冲化方式。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 Х 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.
