Abstract

The invention discloses a micro-Newton-scale ion propulsion device achieving vortex resonant ionization, and belongs to the field of plasma propulsion. The device solves the problem that an existing micro-Newton-scale thruster cannot meet high-pressure thrust control, wide-range continuous thrust adjustment, ultrahigh thrust resolution ratio and long-service-life on-orbit working required in a gravitational wave detecting task. A quartz protection plate is fixedly arranged in a discharge cavity, a plurality of first through holes and a plurality of second through holes are formed in a bottom plate, and a plurality of incense-coil-shaped antennae are arranged on the end face, close to the quartz protection plate, of the bottom plate. The end, located in the center, of each incense-coil-shaped antenna penetrates through the corresponding first through hole to guide out a high-voltage pole and is connected with an output pole of a radio frequency power source, and the end, located on theperiphery, of each incense-coil-shaped antenna penetrates through the corresponding second through hole to guide out a grounded pole and is connected with the output pole of the radio frequency powersource. A screen grid is connected with positive high voltage, and an acceleration grid is connected with low negative voltage, and air inlet holes are formed in an annular side wall between the quartz protection plate and the screen grid.

Description

technical field [0001] The invention relates to a micro-level ion propulsion device for vortex resonance ionization, which belongs to the field of plasma propulsion. Background technique [0002] Gravitational wave detection is a major breakthrough in contemporary physics and astronomy, which determines the development direction of international frontier science; space gravitational wave detection can break through the limitations of surface vibration, gravitational gradient noise, and interference arm length, and study the rich middle ground in black hole astronomy. Low frequency gravitational wave events. To this end, it is necessary to develop an observation system with a baseline length of hundreds of thousands to millions of kilometers. The European LISA project and my country's "Tianqin Project" and "Taiji Project" are currently the most important scientific projects in this field. At the same time, in order to meet the ultra-quiet and ultra-stable attitude and positi...
