Aerospace quadrupole mass filter and method for acquiring atmospheric density and atmospheric components

Abstract

The invention relates to an aerospace quadrupole mass filter for satellites, airships and deep space probes and a method for simultaneously acquiring the natural atmospheric density and the natural atmospheric components in a running orbit of a space craft. The aerospace quadrupole mass filter comprises an ion source assembly, a quadrupole rod assembly, a mandrel assembly and a sensor tube, wherein the ion source assembly comprises an ion source, a shielding grid, an ion injection grid, a collimator and a bushing connecting piece, and the ion source, the shielding grid, the ion injection grid, the collimator and the bushing connecting piece are sequentially connected with one another from top to bottom; the ion source comprises a cathode, an acceleration grid electrode, an electronic suppressor grid, an ion suppressor grid and a gross collection grid; the electronic suppressor grid and the ion suppressor grid are sequentially installed on the ion source from top to bottom; and the gross collection grid is connected between the shielding grid and the ion injection grid. Due to the adoption of the aerospace quadrupole mass filter and the method, the measurement of the atmospheric density and the atmospheric components can be simultaneously realized, and the requirements of high integration, small size and strong space environmental adaptability also can be met.

Description

technical field [0001] The present invention relates to the field of space exploration, in particular to a quadrupole mass filter for space that can be used for satellites, spaceships and deep space probes, and the use of the quadrupole mass filter for space to simultaneously obtain the orbital space of spacecraft. Methods for Atmospheric Density and Natural Atmospheric Composition. Background technique [0002] Space natural atmospheric density and natural atmospheric composition are the most important factors of the space environment. Their changes are affected by factors such as solar activity, geomagnetic disturbance, longitude, latitude, altitude, sub-satellite point local time, and season. They are the main objects of space environment research. . Atmospheric density and atmospheric composition measurements from space have been made for decades. Human beings have a certain basis for understanding the density and composition of the atmosphere. However, with the deepe...

Problems solved by technology

[0005] The problems existing in the existing technology are mainly that the quadrupole mass spectrometer, especially the quadrupole mass filter, has a single function, and cannot realize the measurement of natural atmospheric density and natural atmospheric composition at the same time, and cannot adapt well to the space environment. Under the environment of mechanical vibration, high and low temperature, space radiation, etc., the performance will decrease; Integration requirements
