Abstract
A plasma device for driving magnetic reconnection belongs to the application technical field of low temperature plasma. It solves the problem that the existing space plasma ground simulation device cannot truly study the three-dimensional magnetic reconnection process in space. The present invention can realize magnetopause magnetic reconnection and magnetotail magnetic reconnection; when magnetopause magnetic reconnection is realized, the configuration of the earth's magnetic field is simulated through the dipole magnetic field coil, the configuration of the interplanetary magnetic field is simulated through the magnetic mirror field coil, and the configuration of the interplanetary magnetic field is simulated through the The plasma beam jetted by the plasma gun reconnects the magnetosphere side plasma formed on the Earth's magnetic field configuration and the magnetopause magnetosheath side plasma formed on the interstellar magnetic field configuration at the magnetic zero point; When connected, the dipole magnetic field coil is energized to simulate the configuration of the earth's magnetic field, and the magnetic mirror field coils are used to simulate the configuration of the magnetic field of the earth's magnetotail. The magnetic zero position achieves reconnection. The invention is mainly used to drive the magnetic reconnection process to occur.
Description
technical field [0001] The invention belongs to the application technical field of low-temperature plasma, and in particular relates to a space plasma device which can be used to drive the magnetic reconnection process to occur. 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. [0003] The ground...
