LECR4（兰州ECR4号离子源）是一种室温电子回旋共振离子源，设计用于为现代物理研究所的SSC-LINAC注入器（一种新的扇区分离回旋加速器注入器）产生大电流，高电荷态离子束。LECR4还可以作为蒸发冷却技术在加速器领域应用的PoP机。为了实现这些目标，LECR4 ECR离子源已经优化为在18 GHz工作。2014年，LECR4离子源在1.8 GHz 1.6 kW微波下投入使用。为进一步研究注入阶段对中、高电荷态离子束产生的影响，2015年3月安装了带泵送系统的注入阶段，获得了O(7+) 560 eμA、Ar(11+) 620 eμA、Ar(12+) 430 eμA、Xe(20+) 430 eμA等最优结果。本文将对此进行比较。
LECR4 (Lanzhou ECR ion source No. 4) is a room temperature electron cyclotron resonance ion source, designed to produce high current, high charge state ion beams for the SSC-LINAC injector (a new injector for sector separated cyclotron) at the Institute of Modern Physics. LECR4 also serves as a PoP machine for the application of evaporative cooling technology in accelerator field. To achieve those goals, LECR4 ECR ion source has been optimized for the operation at 18 GHz. During 2014, LECR4 ion source was commissioned at 18 GHz microwave of 1.6 kW. To further study the influence of injection stage to the production of medium and high charge state ion beams, in March 2015, the injection stage with pumping system was installed, and some optimum results were produced, such as 560 eμA of O(7+), 620 eμA of Ar(11+), 430 eμA of Ar(12+), 430 eμA of Xe(20+), and so on. The comparison will be discussed in the paper.
