RAON是一种28 GHz电子回旋共振离子源（ECR IS），作为稀有同位素科学项目进行了设计和测试。预计RAON不仅可以提供稀有同位素光束，还可以提供从质子到铀的稳定重离子。为了获得ECR IS所需的稳定重离子束，必须使用28ghz的微波源和高磁场。设计并制造了一种采用NbTi导线的超导磁体，用于生产ECR IS，并进行了试验。本文介绍了ECR IS超导磁体的设计与制造。实验结果表明，淬火电流随着淬火的发生而增大，但尚未达到设计电流。该实验有望揭示达到设计电流所需的理想条件。
RAON, a 28 GHz electron cyclotron resonance ion source (ECR IS), was designed and tested as a Rare Isotope Science Project. It is expected that RAON would provide not only rare-isotope beams but also stable heavy ions ranging from protons to uranium. In order to obtain the steady heavy-ion beam required for ECR IS, we must use a 28 GHz microwave source as well as a high magnetic field. A superconducting magnet using a NbTi wire was designed and manufactured for producing the ECR IS and a test was conducted. In this paper, the design and fabrication of the superconducting magnet for the ECR IS are presented. Experimental results show that the quench current increases whenever quenching occurs, but it has not yet reached the designed current. The experiment is expected to reveal the ideal conditions required to reach the designed current.
