【摘要】 在过去的十余年中，清华大学加速器实验室致力于X波段同轴磁控管的研发。自2012年成功研制出X波段1.5 MW同轴磁控管(XM-2012)以来，坚持在物理设计、加工工艺和老炼测试等环节进行深入研究，在原有基础上迭代优化出MGT3、MGT4等型号的同轴磁控管，最新样管峰值功率达到1.7 MW以上，与新研发的X波段加速管集成，研制出高稳定性紧凑型加速器系统，剂量率达到800 cGy/min(1 m)以上，达到与S波段加速器系统同等水平；同时对磁控管锁相理论和功率合成进行了大量研究，并在此基础上发展出平行阴极磁控管，将X波段磁控管的输出功率提升到S波段磁控管水平，为进一步拓展X波段高功率磁控管的应用打下了坚实的基础。更多还原

【Abstract】 In the past decade, Tsinghua University Accelerator Laboratory has devoted to the research and development of X-band coaxial magnetrons. Since the successful development of the 1.5 MW X-band coaxial magnetron(XM-2012) in 2012, we have insisted on in-depth research in physical design, processing technology and ageing test. Based on original types, the coaxial magnetrons of MGT3 and MGT4 series are produced with the peak power exceeding 1.7 MW on the latest sample tube. Combining with the X-band linear accelerator, a highly stable compact accelerator system is developed with a dose rate of 800 cGy/min(1 m), which reaches the same level of the S-band accelerator system. At the same time, a lot of research has been conducted on the phase locking theory and power combination of magnetron. On this basis, a parallel cathode magnetron is developed, which raises the output power of X-band magnetron to S-band level, laying a solid foundation for further expanding the application of X-band high-power magnetrons.更多还原
