摘　　要：介绍了纳秒量级的门控积分器。多路积分器采用模块化结构设计 ,每路门完全导通的时间约为7ns,用信号源信号作输入 ,积分非线性不超过 2 .9%。在“星光”装置上的惯性约束聚变实验中 ,每路门控积分器测量结果 ,与示波器积分测量结果对比 ,最大误差不超过满量程的 3.3%。In order to lessen the effect of disturbance in the measurement of the energy and its angular distribution of the soft X ray in Inertial Confinement Fusion (ICF) experiment, a multi channel gated integrator with several nano second turn on time has been developed. The multi channel gated integrator is designed in module structure. The fully turn on time of each gate is about 7 ns, the non linearity is less than 2.9 % when the input comes from a signal source. In a real ICF experiment performed on “Xingguang”facility the maximum error of the multi channel gated integrator, compared with the integral result of the oscilloscope, is less than 3 3% of the full scale. These results demonstrate that multi channel gated integrator satisfies the demands of the ICF experiment.
