电子回旋共振离子源(ECRIS)在癌症治疗和材料合成等领域有着广泛的应用。我们已经构建了一个能够产生各种低到高质量/电荷比的离子的ECRIS，并进行了各种实验。我们专注于有效地产生多电荷离子，并旨在通过ECRIS中电磁波的新效应来增加多电荷离子的产量。我们研究了在低Z气体混合条件下对低Z离子进行选择性加热的可能性。因此，作为实验的初步步骤，研究了低Z气体与稀有气体的混合效应。通过改变混合比，研究了主气Ar和低Z气体He的最佳混合比。测量了Ar多电荷离子束电流、杂质分数和等离子体参数。结果证实，在Ar等离子体中掺入He气体，可充分、可重复地提高Ar多电荷离子产额。此外，从测得的等离子体参数来看，这不是等离子体参数的影响，而可能是冷却效应。
An electron cyclotron resonance (ECR) ion source (ECRIS) has wide applications such as cancer therapy and material synthesis. We have constructed a single ECRIS capable of producing various ions with low to high mass/charge ratio, and have been conducting various experiments. We focus on the efficient production of multicharged ions and aim to increase the yield of multicharged ions by new effects of electromagnetic waves in ECRIS. We investigated the possibility of selective heating to low Z ions under low Z gas mixing. Therefore, as a preliminary step of these experiments, the low Z gas mixing effect with rare gases are investigated. The optimum mixing ratio of the main gas Ar and the low Z gas He was investigated by varying the mixing ratio. The Ar multicharged ion beam current, impurity fraction and plasma parameters were measured. As a result, it was confirmed that the Ar multicharged ion yield was sufficient reproducibly increased by mixing He gas into Ar plasma. In addition, this from the measured plasma parameters is not an effect of the plasma parameters, but maybe a cooling effect.
