用于原子光谱及寿命测量的靶室自动控制装置

Abstract

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。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 se..
