摘　　要：针对ECR离子源的束流引出及传输研究,在中国科学院近代物理研究所的LECR3离子源实验平台上开展了大量的实验.实验中研究了等离子体电极引出孔径、反射电极(抑制电极)偏压以及Glaser透镜等因素对束流引出与传输的影响.研究的重点是试图通过系列实验与分析来研究如何能更有效地引出强流离子束流并减小其在传输空间的损失.给出了实验的主要结果,结合这些数据对ECR离子源的束流引出与传输进行了较全面的分析,并综合这些实验结果与分析结果得出了该物理过程的一般物理图像.Experiments concerning the ion beam extraction and transmission have been done in Institute of Modem Physics on the Lanzhou Electron Cyclotron Resonance Ion Source No. 3 experimental platform. We have studied the influences of the plasma electrode extraction aperture, the biased voltage on the screening electrode and the Glaser lens. The emphasis is put on the research how to extract the ions produced in the source more efficiently and how to make the extracted ion beam transmission with less loss. In this paper, the results of the experiments are presented. With the results obtained, systematic analysis has been made and a general physical image has also been brought forward in this paper.
