A new room temperature electron cyclotron resonance (ECR) ion source, DRAGON, is under construction at IMP. DRAGON is designed to operate at microwaves of frequencies of 14.5-18 GHz. Its axial solenoid coils are cooled with evaporative medium to provide an axial magnetic mirror field of 2.5 T at the injection and 1.4 T at the extraction, respectively. In comparison to other conventional room temperature ECR ion sources, DRAGON has so far the largest bore plasma chamber of inner diameter of 126 mm with maximum radial fields of 1.4-1.5 T produced by a non-Halbach permanent sextupole magnet.
中国科学院近代物理研究所正在建造一台新型室温电子回旋共振（ECR）离子源DRAGON。DRAGON设计用于在14.5 - 18GHz频率的微波下运行。其轴向螺线管线圈采用蒸发介质冷却，分别在注入处提供2.5T的轴向磁镜场，在引出处提供1.4T的轴向磁镜场。与其他传统室温ECR离子源相比，DRAGON目前拥有内径为126mm的最大孔径等离子体腔，由非哈尔巴赫永磁六极磁体产生的最大径向场为1.4 - 1.5T。
