摘要
Abstract
High power microwave research is moving into the high rep-rate regime and it will be common that an electron beam accelerator operates more than a million shots per year.As a result,accumulated brems-strahlung X-ray produced by the electron beam collector is no longer negligible,and shielding is necessary for personnel safety.By using the BEAMnrc Monte-Carlo code,a typical collector for a ring beam usually used in HPM tube is simulated,which has beam voltage 1 MV,beam current 10 kA,pulse duration 100 ns and rep-rate 100 Hz.The results show the spectrum and spatial distribution of the X-ray generated at the collector.The attenuation factor of the X-ray is estimated from the simulation.The estimation of the skyshine radiation is also considered for the roof of the building.关键词
