X波段6 MeV驻波电子直线加速管设计与研制

介绍了以2.2 MW多注速调管作为功率源设计的X波段驻波轴耦合加速管,工作频率为9.3 GHz,工作模式π/2。借助CST优化加速管微波加速结构,实现靶区俘获能量最高6.3 MeV,粒子俘获效率为40.3%,束流流强为120 mA,管芯总长为335 mm(包含电子枪及转换靶),相比现有以1.5 MW磁控管驱动的近700 mm长X波段加速管,总长缩短52%。基于本设计完成腔体加工并进行了腔链调谐,加速管冷测参数与设计参数吻合。

YANG Yong-xuan's Theory on Acupuncture

1 Theory on Superficial Puncture and Cupping Dr. YANG recommended ＂superficial puncture＂. ＂Superficial puncture＂ is named so depending upon the implication of ＂superficial puncture meaning regulation＂. Namely, this technique has the effects to regulate yin and yang, regulate and dredge qi and blood in the meridians and collaterals. The needle tool corresponding to ＂superficial puncture＂ is ＂superficial needle＂. Based upon the descriptions of ＂the theory of nine needles＂ and ＂nine needles and twelve resources＂ in Ling Shu （Spiritual Pivot）. Dr.
