【Abstract】 With the development of accelerator technology,C-band accelerating structure is applied in Shanghai soft X-ray Free Electron Lasers(SXFEL).This paper designs a high power pulse modulator used for 50 MW C-band klystron.The pulse modulator uses thyratron as high voltage switches and pulse forming network to generate pulse waveform.The main parameters of the modulator-klystron systems are peak beam voltage 350 kV,peak beam current 320 A,2.5 μs flattop pulse width and 10 Hz repetition rate.The relevant experiments show that this pulse modulator can meet the requirement of 50 MW C-band klystron.更多还原
