Electron Accelerator Research Center

Brief Introduction

Electron accelerator center is dedicated to advanced electron accelerator physics and technology research, and applied accelerator development and promotion. 

For the advanced electron accelerator physics and technology research, it mainly includes electron linac studies, high energy electron radiography technology (HEER) and application, high beam quality and average beam current injectors, and energy recovery linac and recirculate linac studies. The center has undertaken and achieved many projects supported by the National Natural Science Foundation of China, Ministry of Science and Technology, Chinese Academy of Sciences and local government and so on. Currently, a 50 MeV linac is under operation for HEER and linac experimental studies. Some achievements have been reported in the domestic and international conferences. 

For the applied accelerators development and promotion, it aims for industry application. At present, the electrostatic high voltage electron accelerator (DG series) has been successfully developed and industrialized. Now, the electron curtain accelerator, recirculating coaxial resonator cavity electron accelerator and high voltage electrostatic ion accelerator are under development. 

The center has made good collaboration with ANL(USA), DESY(Germany) and KEK(Japan) on projects and education. 

Currently, there are fifteen members in the center, including 3 researchers and 5 associate researchers. Among them, there are 5 with PhD degrees. Also, there are five graduate students.
