Low-energy direct-current high-voltage type electron accelerator

Abstract

The invention discloses a low-energy direct-current high-voltage type electron accelerator. The electron accelerator comprises a steel cylinder component, a filament power supply, an electronic gun, ahigh-voltage component and an accelerating tube component, wherein the filament power supply, the electronic gun, the high-voltage component and the accelerating tube component are combined with thesteel cylinder component. The filament power supply supplies power to the electronic gun. The high-voltage component is provided with layered voltage-multiplying stages which are connected with voltage-dividing stages of the accelerating tube component, the accelerating tube component is connected with a scanning box through a vacuum tube piece, a vacuum pump component is arranged at a side portion of the scanning box to construct a high-vacuum environment for electron beam output, and a gathering coil is arranged at a lower half portion of the scanning box to gather and use divergent partialbeams. The low-energy direct-current high-voltage type electron accelerator is small in size, low in cost, high in electric energy conversion rate, stable and reliable in work and convenient to overhaul.

Description

technical field [0001] The invention relates to the related technical field of electron accelerators, and more precisely relates to a low-energy direct current high-voltage electron accelerator. Background technique [0002] Electron accelerator is an electromagnetic device that uses artificial methods to make electrons in vacuum accelerated by magnetic field force and electric field force to achieve high energy. The application fields of electron accelerators are very wide, but except for a few large and high-end electron accelerators used as scientific research tools in the field of basic scientific research, a large number of small and medium-sized accelerators are application accelerators. Among them, the industrial irradiation electron accelerator refers to an electron acceleration device used for irradiating various materials, participating in chemical reactions and sterilizing and other industrial production processes. The widely used industrial irradiation electron ...

Problems solved by technology

The above two models have many advantages in terms of medium energy and large beam power, but in the low energy range (below 500keV), because the power supply system such as high-power high-frequency power supply or medium-frequency generator is needed, the internal rectification and voltage doubling system of the accelerator will be upgraded. The internal structure of the electron accelerator is relatively complex, the volume is large, and there are disadvantages such as low efficiency in the low-energy section, difficult maintenance, unfavorable miniaturization, and high manufacturing costs.
