As an important aspect of the application of nuclear technology in the fields of materials, information, etc., energetic ion beams can serve as carriers of both mass and energy and can be precisely manipulated. When interacting with matter, they can generate some extreme conditions that cannot be achieved by conventional physical and chemical methods, thus becoming a frontier growth point in physics and a unique means to carry out related research. Targeting national needs and combining the development of high-tech particle physics experiments, the in-depth study of the interaction between ion beams and matter is a key development direction of this laboratory, which is of great significance for the development of related disciplines and technologies in important fields such as information, materials, and energy, and has significant application value in the national economy and national security. The main contents include:
(1) Basic research on the application of ion irradiation in micro-nano optoelectronic devices
(2) Micro-design and simulation of ion beam material modification
(3) Irradiation effects on fusion structural materials
