Radio Frequency Technology Group
Brief Introduction
The Radio Frequency (RF) technology group is an academic and engineering team with strong R&D capability and experience which dares to take responsibility and be innovate. The team focuses on scientific research, engineering and personnel training in RF technology of linear accelerator, cyclotron and synchrotron. Research covers the fields of magnetic material science, electromagnetic and microwave technology, mechanical design, embedded system, analog digital circuit, automatic control, computer system, etc. The group currently has 21 researchers.
The RF technology group has successively built the RF system of the national first five, Seventh Five and ninth five major scientific facilities. At present, it has undertaken various projects of the Chinese Academy of Sciences, the Ministry of Science and Technology and the National Natural Science Foundation of China, including the Twelfth Five Year Plan of the national development and Reform Commission—high current heavy ion accelerator facility (HIAF) RF system, and the national key R & D plan of the Ministry of Science and Technology research on RF system of high gradient, wide frequency band and fast response magnetic alloy.
The group also conducts research, design and construction of room temperature and high-frequency system in many scientific research tasks, such as Heavy Ion Medical Machine (HIMM), 300 MeV proton &heavy ion accelerator of Space Environment Simulation and Research Infrastructure (SERI), Proton Radiation Effects Facility (PREF), etc.
