摘要: 研制了满足ICF诊断中软X射线能量测量精度要求的具有限定时间积分功能的门控积分器。测试结果表明, 门控积分器的门有效导通时间约为7.8ns; 用信号源做被积信号, 门控积分器与示波器同时测量, 积分非线性小于3%; 门控积分器与示波器测量对比, 最大误差小于门控积分器满量程的5%。Abstract: In order to satisfy the requirement of the soft Xray energy measurement, a gated integrator which integrates the output current to Xray detectors in a limited time has been developed.The tests with signal sources show that the efficient gate width in which the current is integrated is about 7.8ns and the integral nonlinearity is less than 3%. The maximum error between the integral results of the gated integrator and of oscilloscope is less than 5% of the scale range of the gated integrator．
