摘要: 在脉冲射线束测量中,射线以束流形式作用在探测器上,输出电流是许多射线粒子同时作用的叠加效果。当射线源比较弱、探测器探测效率低时,常常显示出统计起伏的现象。本文讨论这种起伏现象,给出了起伏的数学表达形式,讨论了脉冲射线波形测量中统计起伏给各种参数测定所带来的误差。

Abstract: When the waveform of a radiation pulse is measured, a large number of radiation particles interact with the detector simultaneously. The output current waveform is proportional to the waveform of the radiation pulse. The statistical fluctuation phenomenon will appear when the radiation source is relatively weak or the sensitivity of the detector is low. In this paper, the fluctuation phenomenon are considered and mathematical expressions for fluctuation are given. We have also discussed the uncertainty due to statistical fluctuation of various pulse parameters measured, such as amplitude, width, time interval and other special parameters.
