摘要

介绍一个测量由中子引起的核反应的双微分截面实验的事例判选系统，由于反应截面非常小，而且本底相当大，为了最大程度地减少本底的影响，系统采用了二级硬件判选和一级软件判选。经过三级事例判选之后，可使本底计数降低４—５个数量级。

Abstract

Since the very small cross section and the high background in the experiments induced by neutrons

it is very difficult to study the double differential cross section of (n

charged particles) reactions. Besides some special techniques relating to structure of the detector

methodology of mesurement and offline calibration

the event selection techniques should also be considered in the readout and data acquisition sections of measuring system. In this paper an event selection system for the measurement of the double differential cross section of (n

charged partilce) reactions is described in detail.
