Description

technical field

[0001] The invention belongs to the field of microwave masers, in particular to an X-band overmode relativistic klystron amplifier. Background technique

[0002] The relativistic klystron amplifier (RKA) has the characteristics of controllable output microwave frequency and phase, and is suitable for power combination. It is one of the most potential high-power microwave devices at present. The RKA working mode of traditional technology is TM 01 mode, which passes through the drift tube to the TM 01 Mode cut-off, that is, requires R / λ<0.385 (where R is the radius of the drift tube, and λ is the microwave wavelength), to realize the isolation between the cavities. Such as figure 1 As shown, a traditional technique of RKA is given. It includes an annular cathode 1 , an input chamber 3 , a first-stage drift tube 4 , a cluster chamber 6 , a second-stage drift tube 7 , an output chamber 8 and a magnetic field coil 9 . When working, the annular cathode 1 em...
