Abstract
Conference Title: 2019 International Vacuum Electronics Conference (IVEC) Conference Start Date: 2019, April 28 Conference End Date: 2019, May 1 Conference Location: Busan, Korea (South) In this paper, theoretical and PIC simulation of the bremsstrahlung X-ray produced by an X-band gyrotron traveling tube (gyro-Twt)is analyzed with CST Particle Studio, which are used to investigate the X-ray spectra of the collector. X-rays flux spectral density and dose are obtained with theoretical Kramers law when the gyro-TWT operates with saturated output power of 136.9 kW at 9.6 GHz. Studying the X-ray spectra is of great importance for the X-ray protection of the gyro-TWT collector.
