The ion source group has been engaged in advanced ion source research for nearly 40 years and has achieved internationally leading results in the field of advanced high-current ion sources, especially high-charged state ECR ion sources. As the source of accelerators, the group mainly provides stable and reliable high-intensity high-charged state ion beams for advanced ion accelerators such as the Heavy Ion Research Facility in Lanzhou (HIRFL), the High Intensity heavy-ion Accelerator Facility (HIAF), the Low Energy high-intensity heavy-ion Accelerator Facility (LEAF), and the Chinese Accelerator Facility for super heavy Elements (CAFE2). 

Focusing on the forefront of disciplines and the development of ion science and applications, a series of standardized high-charge-state ECR ion source devices have been successfully developed, serving important application scenarios such as heavy-ion large scientific facility, heavy ion therapy facility, single particle effects, and deep underground nuclear astrophysics research. At the same time, the group also carries out research on internationally advanced high-intensity polarized ion sources, polarized ion beam generation, and the physics, technology, and applications of novel high-intensity ion sources.
