Embodiment
[0018] A high voltage of 450kV is applied between the cathode and the anode, and the cathode emits an annular hollow electron beam with inner and outer diameters of 3.0cm and 3.5cm, respectively, and a beam intensity of 6.0kA. Under the guidance of a 0.5T axial magnetic field, the high-current electron beam is transmitted into the beam-wave interaction area, and the electron beam transfers energy to the microwave field. A voltage pulse can generate high-power microwaves with a frequency of 1.56GHz and a power of 500MW respectively.
[0019] The specific selection parameters of the resonator structure are:
[0020] Microwave reflection cavity, the inner and outer radii are 3.8cm and 8.5cm respectively, and the axial length is 2.0cm;
[0021] The beam interaction cavity has an inner and outer radius of 3.8cm and 6.5cm respectively, and an axial length of 3.0cm;
[0022] The first microwave extraction cavity has an inner and outer radius of 3.8cm and 8.5cm respectively, and an a...
