可调谐相对论磁控管的实验研究
An experimental invesigation of frequency-agile relativistic magnetron
-
摘要: 实验研究了高有载品质因数下有无阳极端帽时调谐性能的差异，以及低有载品质因数下，没有阳极端帽时的可调谐相对论磁控管性能。研究结果表明：没有阳极端帽时，可调谐相对论磁控管具有更宽的调谐范围；在高有载品质因数下，可以达到2.52～3.31 GHz的调谐范围，输出功率范围为44～790 MW；低有载品质因数下，调谐范围为2.55～3.05 GHZ，调谐范围内输出功率1～1.7 GW。Abstract: The operating characteristics of S band frequency-agile relativistic magnetron are described. The effects of some factors, such as the anode endcap and the loaded Q value, and the breakdown at the output horn surface are discussed and analysed. The experimental results show that the peak power 1 to 1.7 GW can be generated when the frequency of the tube is adjusted in the range from 2.55 to 3.05 GHz.
