摘要
介绍了１４ＭｅＶ医用驻波加速管的微波调试情况。该加速管的加速能量与束流多档可调，可提供６、１５ＭＶ两档Ｘ射线和６—１４ＭｅＶ五档的电子线。该加速管总长１．４５ｍ，采用轴耦合双周期π／２模驻波结构。利用峰值２．６ＭＷ的脉冲磁控管为功率源，工作频率为２９９８ＭＨｚ，脉冲宽度４μｓ，重复频率为２５０ｙｓ。通过调节入口微波功率、电子枪的注入电压、电流等参数。
A 14 MeV,on axis coupled,S band standing waveguide for madical accelerator is discribed.The guide is designed for dual photons,X ray energies of 6,15 MV and electron beam energies from 6 to 14 MeV.The guide is a single section 1 45 m long,operated in the π/2 mode at 2998 MHz.The tube is driven by a S band magnetron which delivers a 2 6 MW peak power,4 μs width at 250 ys.Energy range is obtained by varying RF power,injection voltage and injected current.In the paper,the microwave cold test process is described and the tuning result is given.
