Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0028] The invention relates to a double electron beam electron gun, which can generate double cyclotron beams, and place the double cyclotron beams on different guide center radii of the gyrotron interaction circuit, which is equivalent to the high-order work of the gyrotron Modes introduce additional boundary conditions that facilitate the excitation of higher-order operating modes within the interacting circuit, thereby effectively suppressing the formation of lower-order non-operating competing modes.

[0029] In a basic embodiment of the invention, a dual beam electron gun is provided. The double electron beam electron gun can generate two electron beams, including: a first anode, a first cathode and a second cathode...

Abstract

The invention discloses a double electron beam electron gun and a gyrotron. The double electron beam electron gun can produce two beams of electron beams and comprises a first anode, a first cathode and a second cathode, wherein the first cathode is under the action of a voltage between the first cathode and the first anode and generates a first electron beam, and the second cathode is under the action of a voltage between the second cathode and the first anode and generates a second electron beam. The electron gun with double cathodes not only can be applied in the field of gyrotron, but also can be applied in other fields of the microwave industry.

Description

technical field [0001] The invention relates to the field of microwave technology in the electronics industry, in particular to a double electron beam electron gun and a gyrotron. Background technique [0002] Gyrotron is a new type of coherent microwave radiation source device, which can work in high frequency band and has high power capacity and working bandwidth. Gyrotron is used in imaging radar, electronic countermeasures, directed energy weapons, material processing, plasma heating and other fields It has broad application prospects. [0003] With the increase of the working frequency of the gyrotron, the lateral geometry size of the gyrotron is getting smaller and smaller, and the power capacity of the gyrotron is also gradually reduced. In order to expand the lateral geometry size of the gyrotron and improve the power capacity of the gyrotron, the gyrotron will select a higher-order working mode. The biggest problem faced by the gyrotron working in the high-order w...
