摘　　要：一台有效、快速、电子束相图自动测量装置已在我们实验室设计、加工、安装完毕。利用了单缝-多丝测束方法。由计算机控制,进行数据采集和数据处理,显示出束流相图,算出相面积以及束流强度百分比不同的发射度。并初步研究了电子枪阴极加热电流对电子枪初始发射的影响。An automatic device for the effective and rapid measurement of electron beam emittance has been designed and installed in our laboratory.The computer control System of the 'Single slit-multiple wires' has been used for data acquisition and processing,and beam phase diagram displaying; for beam phase area and percentage of beam current strength and emittance ealculation. The effects of cathod heating current of the electron gun on the initial emittance have been studied preliminarily.
