The Space Environment Simulation and Research Infrastructure project, which uses various ion beams as irradiated materials in life science research, is being built at the Harbin Institute of Technology. A new room temperature electron cyclotron resonance ion source, the Lanzhou Electron Cyclotron Resonance Ion Source No. 5 (LECR5), has been designed and constructed. It is an intense, highly charged, heavy ion beam injector which generates ion beams from H to Bi, typically ∼50 eμA 209Bi32+. The LECR5 is designed to operate at microwave frequencies in the range of 14.5-18 GHz. The typical magnetic parameters are designed based on those optimized for SECRAL, which operates at 18 GHz. This paper presents the LECR5 ion source, its test bench, and the preliminary beam results.

用于 SESRI 项目的新型室温 LECR5 离子源

在生命科学研究中使用各种离子束作为辐照材料的空间环境模拟与研究基础设施项目正在哈尔滨工业大学建设。设计并建造了一种新型室温电子回旋共振离子源——兰州电子回旋共振5号离子源（LECR5）。它是一种强、高电荷、重离子束注入器，可产生从 H 到 Bi 的离子束，通常约为 50 eμA 209Bi32+。LECR5 设计用于在 14.5-18 GHz 范围内的微波频率下运行。典型的磁参数是根据为 SECRAL 优化的参数设计的，SECRAL 工作频率为 18 GHz。本文介绍了 LECR5 离子源、其测试台以及初步的离子束结果。
