Abstract

The invention discloses a ground simulation device and method for simulating large-scale magnetopause magnetic reconnection, and relates to the technical field of application of low temperature plasmas. The problem of the lack of a device which can directly reflect structural characteristics of an interplanetary magnetic field at present is solved. An upper magnetic-mirror field coil and a lower magnetic-mirror field coil located in the same vertical direction are of the same structure and are elliptic coils, the ellipse length-diameter ratio is greater than or equal to 1.5, an electron cyclotron resonance plasma source is used for injecting electromagnetic waves into a dipole magnetic field, so that at a resonant magnetic field surface generated by the dipole magnetic field, the electromagnetic waves ionize working gas in a vacuum chamber to generate plasmas in a simulated space, the upper magnetic-mirror field coil and the lower magnetic-mirror field coil are used for generating a magnetic-mirror field magnetic field to simulate a uniform interplanetary magnetic field, and magnetic zeros exist between the dipole magnetic field coil and the upper magnetic-mirror field magnetic field and the lower magnetic-mirror field magnetic field. The ground simulation device and method are used for simulating a magnetopause magnetic reconnection process.

Description

technical field [0001] The invention relates to a space plasma ground simulation device and method which can be used to simulate large-scale magnetopause magnetic reconnection. It belongs to the application technical field of low temperature plasma. Background technique [0002] The most direct way to study the space plasma environment and its interaction with spacecraft is to use space detection. Through a large number of satellite observations, people have made great achievements in the study of the space plasma environment and its physical processes. However, space satellite detection is difficult to obtain global observation data at the same time. Therefore, while extensively carrying out space exploration and on-orbit experiments, establishing ground simulation devices and conducting ground simulation research on space science experiments have important scientific value and urgent practical significance for the progress of scientific frontiers and major national needs...
