The Low-Energy Particle Beam Technology Center was established in 2025 and consists of three divisions: the Ion Source group, the Low-Energy Particle Beam Application group, and the Electron Accelerator group.

The Ion Source group is dedicated to the frontier exploration, research, and operation of high‑performance ion sources, and continues to make breakthroughs in the production of highly charged ions from electron cyclotron resonance (ECR) ion sources and in the stable operation of highly charged and high-intensity ion beams. As the source of accelerators, the group mainly provides stable and reliable high-intensity high-charged state ion beams for advanced ion accelerators. Based on existing facilities, the platform supports research in atomic physics, nuclear astrophysics, material irradiation, and more, while also engaging in collaborative efforts at home and abroad on ECR ion source design, development, and system integration.

The Low-energy Particle Beam Application Group conducts particle beam application research targeting large scientific facilities and major national strategic needs. On the one hand, focusing on advanced facilities such as HIAF, the group carry out research on the acceleration and manipulation of low-energy high-intensity ion beams, multi-beam combination and injector upgrading. On the other hand, centering on the semiconductor industry, it leverages the advantages of high-charge-state ion sources and radiofrequency accelerators. It collaborates with leading enterprises to tackle core technologies of high-energy ion implanters and advance the industrialization of domestic equipment. In addition, it develops electromagnetic purification technologies for high-abundance stable isotopes and support the cutting-edge development of relevant disciplines.

The Electron Accelerator Group is dedicated to the research and development of applied electron accelerators and their application technologies. The group has made significant progress in several key areas, including high-current electron accelerator technology, high-energy electron imaging and its applications, the development of applied accelerators, and high-quality electron injectors. A notable achievement is the construction of the Lanzhou High-energy Electron Imaging Research Facility.
