摘要

研制了一套用于原子激发光谱及激发能级寿命测量的，由计算机、步进马达等九部分组成的靶室自动控制设备。软件由主控程序等三个分程序组成。靶位移动全程为６５ｃｍ，步距为８．３ｕｍ，精度为２ｍｍ±１８ｕｍ。设备结构简单、运行可靠、操作方便，常用参数可外输入，并有双重保护。

Abstract

An automatically controlled apparatus of target chamber was made to measure spectra of the excited atoms and lifetime of the excited levels. The hardware is composed of nine parts including a computer and a step-motor

while the software consists of three branch programs. The maximum movable distance of target position is 65cm with a step-length of 8.3 u m and a precision of ±18 u m per 2mm. On account of simple structure and double

protection

the apparatus exhibits flexibility and reliability in years service.
