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。
A powerful high-charge electro-permanent magnet (ECR) ion source LAPECR2 (LAPECR2) LAPECR2 was successfully developed. The ion source has been successfully installed on the 320 kV high voltage platform of the Institute of Modern Physics after the magnet assembly is completed, and the ion source is assembled with the post-mooring line. The ion source achieved its first successful arcing at 14.5 GHz in July 2005 and led to a stronger mixed beam. At present, the ion source has been combined with the back-beam and some experimental terminals to obtain the ion beam current of the high-intensity and high-charge state in the experimental terminal. This article will focus on the structural characteristics of the all-permanent magnetic source and the main parameters of indicators. This paper also focuses on the preliminary commissioning results of the LAPECR2 ion source under the condition of 14.5 GHz microwave power feed. On the basis of this, the experimental results of the beam-to-end experiment are discussed. The influence of beam extraction and transmission efficiency The main factor.
