美国国立放射科学研究所为新的碳治疗设施开发了具有永久磁铁配置的紧凑型电子回旋共振（ECR）离子源（Kei 2源）。Kei2源是为产生C（4+）离子而设计的，其束流强度和稳定性等性能已达到医用要求。至此，医用电源样机研制基本完成。最近，我们已经开始了一些关于该源的其他应用的研究。一个是在ECR等离子体中生产富勒烯和用于新材料的具有各种原子的改性富勒烯。第二个应用是产生用于离子注入的多电荷离子（不仅仅是碳）。本文报道了这些应用的一些基本实验。
The compact electron cyclotron resonance (ECR) ion source with a permanent magnet configuration (Kei2 source) has been developed at National Institute of Radiological Sciences for a new carbon therapy facility. The Kei2 source was designed for production of C(4+) ions; its performance such as beam intensity and stability has already reached the medical requirements. Therefore, the prototype development of the source for medical use is essentially finished. Recently, we have started a few studies on other applications of the source. One is the production of fullerenes in the ECR plasma and modified fullerenes with various atoms for new materials. A second application is the production of multiply charged ions (not only carbon) for ion implantation. In this paper, some basic experiments for these applications are reported.
