摘　　要：与单注速调管相比,多注速调管可以工作在较低的电子注电压,具有较小的体积和重量。为了满足散裂中子源、加速器驱动次临界堆和同步辐射光源所用的高能质子加速器对高功率微波器件的需求,中国科学院电子学研究所开始进行P波段1.2 MW多注速调管的研究。采用30个电子注,P波段多注速调管的电子注电压为35kV,阴极负载小于2.5A/cm2。计算表明:采用5个谐振腔(其中包括一个二次谐波腔),P波段多注速调管可获得输出功率1.282 MW,效率69.7%,增益45.6dB,其高频互作用长度仅为600mm,整管长度可小于2000mm。论文给出了P波段多注速调管的设计考虑和计算结果,并对多注速调管、多注感应输出管和单注速调管的性能作了比较。Comparing with single beam klystron,multi-beam klystron（MBK）can operate at lower beam voltage,and has smaller volume and weight.To satisfy the requirement of high energy proton accelerator for spallation source and ADS（accelerator driven sub-critical system）,the design and calculation of a P-band 1.2 MW MBK was made in Institute of Electronics,Chinese Academy of Sciences（IECAS）.By using 30 beams,the P-band MBK can work at beam voltage of 35 kV with cathode loading of2.5 A/cm2.By using 5 cavities（one of them is 2 ndharmonic cavity）,the P-band MBK can obtain peak power of 1.282 MW,efficiency of 69.7 %,and gain of 45.6 dB with interaction section length of 600 mm.It makes the total length of MBK less than 2000 mm.The design consideration and calculation results are present in the paper.Also the comparison among MBK,multi-beam-IOTand single beam klystron was made.
