Abstract

The invention provides a tunable relativistic klystron amplifier output cavity. The tunable relativistic klystron amplifier output cavity provided by the scheme comprises a drift tube, a first inner sleeve, a second inner sleeve, a first adjustment screw rod, a second adjustment screw rod, an output cavity external cylinder and an output segment, wherein the drift tube is arranged at a left end of the output cavity external cylinder, the output segment is arranged at a right end of the output cavity external cylinder, the first inner sleeve and the second inner sleeve are arranged between the output segment and the output cavity external cylinder, the first inner sleeve is connected with the first adjustment screw rod, and the second inner sleeve is connected with the second adjustment screw rod. In the tunable relativistic klystron amplifier output cavity provided by the scheme, the first inner sleeve and the second inner sleeve are arranged in the output cavity, thus, the diameter of the output cavity can be changed by moving the positions of the first inner sleeve and the second inner sleeve, and the output cavity can be tuned to work in different wave bands on the condition of no damage to vacuum.

Description

technical field [0001] The invention relates to the field of microwave electronics, in particular to a tuneable relativistic klystron amplifier output cavity. Background technique [0002] With the development of high-power microwaves, high-power microwave sources that can work in multiple bands have become a new development direction of high-power microwave technology. Because the relativistic klystron amplifier (RKA) has the advantages of high power, high efficiency, stable output microwave phase and amplitude, it is one of the most potential high-power microwave generating devices, and has been widely used in communications, radar, navigation, and linear accelerators and other fields. However, the size of the high-frequency cavity of the conventional relativistic klystron amplifier cannot be mechanically tuned, and usually only works in a single band, which limits the application range of RKA. Therefore, in order to improve the working performance of RKA and expand its ...
