Embodiment Construction

[0015] specific implementation plan

[0016] In order to help a better understanding of the present invention, specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0017] FIG. 1 is a thermon structure of a conventional magnetron injection electron gun, and the shape of the thermon structure is a truncated circular double helix structure.

[0018] Figure 2A , Figure 2B , Figure 3A , Figure 3B It is a thermal substructure of a magnetron injection electron gun of the present invention.

[0019] The conventional frusto-conical double-helical thermal substructure (shown in Figure 1) is changed into a circular helical thermal substructure ( Figure 2A , Figure 2B , Figure 3A , Figure 3B Shown), this can increase the length of the heater winding wire (usually tungsten wire or rhenium tungsten wire), thereby increasing the resistance of the heater and achieving the purpose of increasing the heating power of...

Abstract

The present invention discloses a heater structure of magnetron injection gun, which relates to microwave technology. The heater is formed by the circular ring circled by spiral cylindrical tungsten filaments or rhenium tungsten filaments. First structure of the heater is that two semicircles are formed by spiral cylindrical tungsten filaments or rhenium tungsten filaments; the two ends of each semicircle are provided with a bar-shaped lead; and a circular ring is then formed by fixedly connecting the four bar-shaped leads in pairs. The second structure is that the spiral cylindrical tungsten filaments or rhenium tungsten filaments are shaped into a circular ring, of which the two ends are provided with straight-bar-shaped leads having a clearance arranged therebetween. The heater structure of the present invention is applicable to various magnetron injection guns of gyrotron, and the processing technology is easy and convenient. Moreover, the heater is high in heating efficiency and is unlikely to bring about short-circuit failure.

Description

technical field [0001] The invention belongs to the field of microwave technology, and in particular relates to a thermon structure of a magnetron injection electron gun of a high-power gyrotron microwave source. Background technique [0002] The gyrotron is a new type of coherent microwave radiation source device, which can work in a higher frequency band and has a higher power capacity and operating bandwidth; the gyrotron has great potential in the fields of material processing, plasma heating, electronic countermeasures, radar and communication systems Wide application prospects. [0003] As the operating frequency of the gyrotron increases, the lateral structural size of the gyrotron device becomes smaller and smaller; the structural size of the magnetron injection electron gun, which is a key component of the gyrotron, also gradually decreases with the increase of the operating frequency. The smaller structure of the magnetron injection electron gun puts forward highe...
