Gyrotron collector

Abstract

The invention provides a gyrotron collector. The gyrotron collector comprises a transition section, a cylinder section which is connected with the transition section in a sealing manner, and a top cover which is connected on the rear side of the cylinder section in a sealing manner. An inner side of the top cover is provided with a bulge toward the cylinder section. The gyrotron collector can effectively intercept and capture abnormal clutter electrons generated by influence of space charge forces among electron beams and disturbance of a high-frequency electromagnetic field excited by the electron beams, and controls the mussy abnormal electrons in an effective region, preventing appearance of uncontrollable air leaking points, and improving work stability of high power gyrotrons.

Description

technical field [0001] The invention belongs to the field of microwave technology, in particular to a gyrotron collector. 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] The gyrotron can be divided into two types according to the microwave output structure: one is the gyrotron with an axial output structure, and the gyrotron with this type of structure usually adopts a low-order circular symmetry working mode, and the collector for recycling the cyclotron beam is also a The output channel of high-power microwave is limited by the output waveguide mode conversion, the power capacity of the collector of this type of gyrotron is greatly limited; the other ...

Problems solved by technology

Compared figure 1 It can be seen from Fig. 2 that although the landing width of the cyclotron beam on the collector wall has increased, due to the influence of the charge force between the electron beams and the interference of the electromagnetic field, the cyclotron beam cannot completely land on the collector wall.

[0006] In the process of realizing the present invention, the applicant found that the conventional conical structure of the gyrotron collector has the following defects: in the actual work process, the gyrotron beam is caused by the high-frequency electromagnetic field caused by the charge force between the electron beams and the electron injection. Affected by the disturbance, abnormal messy electrons will be formed, so that the cyclotron beam cannot all land on the collector wall, causing some electrons to uncontrollably land on other areas of the collector, forming new gas outlet points, thus causing high-power cyclotrons tube work instability
