Development of a C-band 6 MeV standing-wave linear accelerator

Abstract

C-band low-energy electron linear accelerators are preferable for applications which require compact structure and accurate positioning. During the past two years, the accelerator laboratory of Tsinghua University has developed a C-band 6 MeV standing-wave biperiodic on-axis coupled linear accelerator. The weight of the accelerator is 7.4 kg and the length is about 39 cm, which includes the thermal-cathode gun and the flange for tests. High capture ratio, narrow energy spectrum, and small spot size have been achieved in the high power rf test, which shows good performance of this accelerator and its great potential for industrial and medical applications.
