Electron accelerator

Abstract

An accelerator comprises a steel cylinder, a high-frequency transformer which is arranged on the steel cylinder, a plurality of semi-circular equalizer rings which are arranged inside the steel cylinder, a high pressure electrode which is arranged on the equalizer rings, two pieces of high-frequency electrodes which are arranged outside the equalizer rings and the high pressure electrode, an electron gun which is used to produce and excite electrons with a filament, a filament transformer which is used to regulate filament voltage and a vacuum accelerating tube which is arranged under the electron gun, wherein a plurality of semi-circular equalizer rings adopt a mode that openings are opposite to symmetrically line up into two lines along the steel cylinder axial cord direction. The equalizer rings comprise ring bodies, connecting pieces which are fixedly connected with the ring bodies and two end portions which are located on two ends of the ring bodies, wherein the whole equalizer rings are provided with C-shaped cross sections, the ring bodies are provided with outer surfaces which are corresponded with the steel cylinder and inner surfaces which are corresponded with the outersurfaces, the indent sides of C-shaped cross sections openings are inner surfaces, and the inner surfaces are arranged to the axial cord of the steel cylinder. The accelerator has the characteristicsof simple structure, light weight, good ring gap consistency.

Problems solved by technology

The pressure equalizing ring with such a hollow tube structure increases the weight of the pressure equalizing ring due to the arrangement of the inner side of the circular arc which has no effect. Moreover, the stainless steel material used in the existing pressure equalizing ring has a relatively high density because of its high density. The weight of the pressure equalizing ring has been greatly increased, and the pressure equalizing ring needs to be installed on the stem during the working process. The heavy weight will affect the installation stability of the pressure equalizing ring, and then affect the work of the accelerator.

[0005]The pressure equalizing ring of this structure can only be processed by mechanical pressing or sheet metal working by bending pipes into a ring, and it cannot be processed at one time Molding, mass production, not only the processing process is complicated, but more importantly, it is difficult to ensure that each equalizing ring has the same physical characteristics, and the scrap rate is high

During use, due to the high voltage between the grading ring and the high-frequency electrode, the inconsistency between the grading rings will cause electric field distortion, affect the high-voltage resistance level and high-voltage stability of the accelerator, and cause corona and breakdown and other phenomena, and make the insulation characteristics between the grading ring and the high-frequency electrode worse
