Device for collecting space thermal plasmas

Abstract

The invention belongs to the technical field of space plasma detection equipment, and particularly relates to a device for collecting space thermal plasmas, which comprises a round cover (1), an outer electrode plate (2), an upper electrode ring (3), a lower electrode ring (4), a deflection plate (5), an inner electrode plate (6) and an insulating bottom frame (7), the round cover (1) is arranged at the top of the outer electrode plate (2); an upper electrode ring (3) and a lower electrode ring (4) are sequentially arranged in a cylindrical cavity formed in the middle between the round cover (1) and the outer electrode plate (2) from top to bottom, a plurality of first fixing blocks (9) which are circumferentially distributed are additionally arranged on the outer walls of the upper electrode ring (3) and the lower electrode ring (4), and a deflection plate (5) is additionally arranged in the lower electrode ring (4); an inner electrode plate (6) is sleeved in the middle of the outer electrode plate (2), and an insulating underframe (7) is arranged below the bottom of the outer electrode plate (2) and the bottom of the inner electrode plate (6); and the device is simple in structure and light in weight, and plasmas in more directions can be incident.

Description

technical field [0001] The invention belongs to the technical field of space plasma detection equipment, and in particular relates to a device for collecting space thermal plasma. Background technique [0002] Space hot plasma with certain energy (velocity) exists everywhere in the deep space of earth space, interplanetary space and other planet space in the solar system, which includes: electrons, ions and unionized neutral particles. The detection of space thermal plasma can allow people to better understand the physical phenomena of the solar-terrestrial space, which is of great significance to the study of the evolution of the space environment and the exploration of the unknown, and helps humans to deeply understand the laws of solar-terrestrial interaction and energy coupling . The study of space plasma has promoted the development of the causal chain research of the sun-interplanetary-earth magnetosphere-near-Earth space disturbance, and then effectively forecasted s...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing devices for collecting space thermal plasma are very heavy and have a single entrance, which cannot realize the incident of 360-degree space thermal plasma; and on the space station, because each component is very unstable, thus Affect collection effect
