Abstract
This paper describes -40kV high voltage solid state pulse power modulator (SSPPM) for driving a magnetron, which is used as a RF power source of LINAC for cancer treatment systems. In case of the medical LINAC, small size and light weight are required. The SSPPM is 92 liters in size and weighs 50 kg. In this paper, S-band 2.6 MW magnetron load experiment is conducted and impedance matching was applied to obtain a smooth output current. Finally, the experimental results is discussed and the reliability of SSPPM is verified.
