本文对差分单道毫微秒时间分析器的基本原理及优缺点作了较为全面的论述,讨论了实际使用中存在的问题,最后,还提出了一些有关实验方法及简化仪器的改进意见。在实验中证明仪器是稳定可靠的,在加速器的配合下作出了一些元素的中子能谱。电子学线路本身的分辨时间为1毫微秒,包括加速器束流宽度、相位稳定和探测元伴的分辨时间在内的分辨时间为6—7毫微秒。
In this paper, the basic principle, advantages and disadvantages of differential single nanosecond time analyzer are discussed in detail, and the problems in practical use are discussed. Finally, some improvements on experimental methods and simplified instruments are also proposed. The experiment proves that the instrument is stable and reliable, and some elemental neutron energy spectra have been made under the cooperation of accelerators. The resolution time of the electronics circuit itself is 1 nanosecond, with a resolution time of 6-7 nanoseconds, including the width of the accelerator beam, the phase stability, and the resolution of the detector element.
