Embodiment 1

[0035] A preferred embodiment of the present invention provides a device that utilizes ultraviolet radiation and an electron gun to generate a flow of neutral dust particles. The outer diameter of 103 is smaller than the inner diameter of the ionization chamber, and is connected to the ionization chamber through the first insulating column 105 to form a concentric circle structure; the observation window 108 is fixed on one side of the ionization chamber 1 through a sealing gasket 107 and a fastening knob 109; the upper part of the discharge electrode 103 is Place a cylindrical dust container 106 with a radius of 3 cm and a height of 1.5 cm. The bottom of the dust container 106 is made of metal mesh with an interval of 5 microns (the container can be replaced, and the mesh holes at the bottom have different sizes), and the metal dust is placed in the container. A vibrating device with a timer function is installed on the container, and when the container vibrates, the dust fall...

Abstract

The invention discloses a device for generating neutral dust particle flow by utilizing ultraviolet radiation and an electron gun, and relates to the technical field of dust particle accelerator equipment. The device comprises an ionization cavity, an acceleration cavity, an electron gun neutralization channel and a deflection cavity which are sequentially communicated end to end, and the ionization cavity, the acceleration cavity, the electron gun neutralization channel and the deflection cavity are all in a horizontal cylinder shape with two open ends; the device further comprises an electric system; an ionization assembly and a radiation assembly are arranged in the ionization cavity; the acceleration cavity is provided with an acceleration assembly; an electronic gun body is arranged on the side edge of the electronic gun neutralization channel in a communicating manner; a deflection assembly is arranged on the outer side wall of the deflection cavity, insulating rings are arrangedbetween the tail end of the acceleration cavity and the head end of the electron gun neutralization channel and between the tail end of the electron gun neutralization channel and the head end of thedeflection cavity respectively, and the device has the potential advantages of being easy to use, low in cost and safe in operation.

Description

technical field [0001] The invention belongs to the technical field of dust particle accelerator equipment, and in particular relates to a device for generating a neutral dust particle flow by using ultraviolet radiation and an electron gun. Background technique [0002] Space debris refers to the waste and its derivatives produced by human beings in space activities, mainly including abandoned spacecraft, the last stage of rockets, discarded objects during mission execution, rocket explosives, space vehicle disintegration and debris collisions fragments etc. Space debris is the main source of pollution in the space environment. The increasing number of space debris in orbit will definitely affect and threaten the sustainable use of space resources by humans. Space debris removal is an important issue that future space missions must face. [0003] The main technical means of space debris removal at home and abroad include three types: pushing deorbiting, increasing resistan...
