JYFL-ACCLAB-ISG003 CUBE-ECRIS operation with 2-frequency heating and gas mixing

Results of an experimental campaign performed with the CUBE-ECRIS ion source to study the effects of single and double frequency plasma heating and gas mixing on the ion source performance. The ion source was operated with a slit extraction system. The experiments included measurements of extracted ion beam currents, ion charge state distributions, and emissions of bremsstrahlung and microwaves from the ion source. The studies included operation of the ion source in continuous mode and also measurements of the plasma ignition and decay transients. Ar, Kr and Xe were used as primary plasma elements and He, N and O as mixing gases. The experimental work was carried out in November and December of 2022.

本实验研究工作依托CUBE-ECRIS离子源开展，旨在探究单频与双频等离子体加热、气体混充对离子源性能的影响。该离子源采用狭缝式引出系统进行运行测试。本次实验涵盖引出离子束流强度、离子电荷态分布，以及离子源产生的轫致辐射与微波辐射的测量工作。研究内容包含离子源的连续运行模式测试，以及等离子体点火与衰减瞬态过程的测量。实验采用氩（Ar）、氪（Kr）与氙（Xe）作为等离子体主体工作气源，以氦（He）、氮（N）与氧（O）作为混充气。本实验工作于2022年11月至12月期间完成。
