双通道穆斯堡尔谱仪系统

A Dual Channel Moessbauer Spectrometer System

本文叙述一个用单片机进行在线控制和数据获取的双通道穆斯堡尔谱仪系统。该谱仪被设计成一个单宽 NIM 插件,可直接插在 NIM 机箱中运行。谱仪可自动地完成能谱测量,能窗选择和穆谱测量。由于在结构上进行了专门的考虑。本谱仪可以很容易扩展成更多通道的系统,并可直接用于其它数据获取系统中。

In this paper,a dual channel Moessbauer spectrometer system in which a single chip processor is used for on-line control and data acquisition is described.The spectrometer is designed in a single-width NIM module and can be performed directly in NIM crate.The spectrometer can implement the measurements of energy spectrum,the choices of energy window and the measurements of Mossbauer automatically.Be- cause the structure of the spectrometer is considered specially,the more channel systems are easy to be setup by it.This spectrometer can also be used in other data acquisition systems.
