摘要

研制成功了一台强流高电荷态全永磁ECR（Electron Cyclotron Resonance）离子源LAPECR2（Lanzhou All Permanent Magnet ECR Ion Source No.2）。该离子源在完成磁体装配后已成功在近代物理研究所320 kV高压平台上安装就位

与后束运线完成对接组装。离子源于2005年7月在14.5 GHz实现了第一次成功起弧

并引出较强的混合束流。目前离子源已与后束线以及部分实验终端完成了联调

在实验终端能够获得强流较高电荷态的离子束流。本文将着重论述该全永磁源的结构技术特点和主要参数指标。本文还着重论述了LAPECR2离子源在14.5 GHz微波功率馈入条件下的初步调试结果

在此基础上对束流向实验终端联调的实验结果进行了讨论

着重分析了影响束流引出与传输效率的主要因素。

Abstract

The world biggest all permanent magnet Electron Cyclotron Resonance (ECR) ion source with the highest magnetic field has been successfully designed and fabricated at IMP

which is named LAPECR2 (Lanzhou All Permanent magnet ECR ion source No. 2). After being assembled

LAPECR2 source was situated on the 320 kV high voltage platform at IMP and connected to the successive ion beam transmission beam line. The first plasma of LAPECR2 was obtained in July 2005 with 14.5 GHz microwave power injection

and an intense mixing ion beam had also been extracted at the same time. Presently

the on-line test of the source LAPECR2 with the successive experimental beam line has been accomplished

and many kinds of intense high charge state ion beams have been detected at the experimental terminals. After a detail introduction of the ion source structure

the main characteristics are given. Then the preliminary results of the source at 14.5 GHz rf power injection are presented. After that

the on-line tuning results with the experimental beam line are presented and some corresponding discussion is also given. The aspects that affect the performances of the beam line are tentatively investigated in this paper.
