英文摘要:

      In this paper, a new output structure is proposed for the output system of 50 MW high-power multi-beam klystron in C-band, TM310 high-order multi-beam structure is proposed for the first time, which can greatly reduce the operating voltage of the whole tube from 354 kV to 250 kV and shorten the length of the whole tube from 1. 4 m to 0. 9 m. The rectangular TM310 structure is innovatively adopted and the output waveguide compensation structure is combined to effectively solve the problem of insufficient external quality of the circular TM310 structure and ensure the output stability of the whole klystron. The C-band 50 mW multi-beam klystron proposed in this paper can greatly reduce the operating voltage and volume of the whole klystron, which can greatly improve the reliability and maneuverability of the system. The high frequency system of C-band 50 mW multi-beam klystron with new structure studied in this paper effectively solves the problem of high order mode and high power stable output, reduces the design complexity of output structure, the volume of transmission system and the cost. It is of great significance for the design of multi-beam peak power products in the future.
