一、引言多道脉冲幅度分析器(简称多道分析器)是为满足核物理能谱分析的需要而研制出来的核子仪器。它能把射线所产生的脉冲讯号按幅度进行分类,从而确定射线的能量和强度。还可以附有获取射线在时间和空间位置方面的数据。通常这种类型的设备均具有一些简单的数据处理功能:例如,全谱的积分、感兴趣谱段的求和、两个谱的相加或相减等等。
I. INTRODUCTION Multichannel pulse amplitude analyzer (Multi-channel analyzer) is a nuclear instrument developed to meet the needs of nuclear physics energy spectrum analysis. It can pulse the pulse generated by the signal classification, in order to determine the radiation energy and intensity. It is also possible to attach data on the position of the ray in time and space. Often, devices of this type have some simple data processing capabilities: for example, the integration of the full spectrum, the summation of the bands of interest, the addition or subtraction of the two spectra, and so on.
