Embodiment 1
[0038] Such as figure 1 As shown, a C, X-band dual-frequency controllable compact high-power microwave device of this embodiment includes a circular waveguide outer cylinder, an inner conductor coaxial with the circular waveguide outer cylinder, the inner conductor and the circular waveguide outer cylinder A vacuum electron beam transmission channel is formed between the cylinders, and the annular electron beam is transmitted in the electron beam transmission channel;
[0039] The microwave device is sequentially provided with a C-band slow-wave structure and an X-band slow-wave structure including an inner conductor, and an axially movable metal circular waveguide is arranged between the C-band slow-wave structure and the X-band slow-wave structure. The outer diameter of the circular waveguide is the same as the inner diameter of the microwave device;
[0040] The ratio of the total axial length of the C-band slow-wave structure to the C-band radiation wavelength is 1.6, the...
Embodiment 2
[0051] Such as figure 2 As mentioned above, the difference between this embodiment and Embodiment 1 is: in the embodiment, the vacuum degree in the microwave device is processed to the order of milliPascal by using a vacuum obtaining device, and the fourth cavity of the C-band slow wave structure is controlled by the metal circular waveguide body. A high voltage of 380kV is applied between the cathode and the anode, and the cathode emits a ring-shaped electron beam with an inner and outer diameter of 60mm and 70mm, respectively, and a beam intensity of 6kA. The ring-shaped electron beam is transmitted into the device under the guidance of a 0.63T axial magnetic field, and the electron beam transfers energy to the microwave field, generating high-power microwaves with a frequency of 8 GHz within one pulse.
[0052] In summary, the use of a C, X-band dual-frequency controllable compact high-power microwave device of the present invention can greatly reduce the volume and weigh...
