Ground simulation research device for interaction of near-earth space plasma and laser

Abstract

The invention discloses a ground simulation research device for interaction of near-earth space plasma and laser. The ground simulation research device comprises a vacuum pump, a vacuum cavity, an electromagnetic wave emission mechanism, tunable laser and a detector; the vacuum pump is used for adjusting the vacuum degree in the vacuum cavity; a magnet exciting coil and a plasma generating mechanism are arranged in the vacuum cavity, the magnet exciting coil generates a magnetic field with adjustable intensity, and the plasma generating mechanism generates plasmas and conveys the plasmas into the magnetic field; the electromagnetic wave emission mechanism is arranged outside the vacuum cavity, has a frequency and power adjustable function, and sends electromagnetic waves to pass through a quartz window of the vacuum cavity to be sent into the magnetic field; the tunable laser is of an irradiation angle adjustable structure, the detector is of a receiving angle adjustable structure, and laser sent by the tunable laser penetrates through the magnetic field and the plasma to be sent to the detector; the device can realize simulation adjustment of various parameters, so that the problem of single research function in the prior art is practically solved.

Description

technical field [0001] The invention relates to the technical field of plasma-laser interaction simulation, in particular to a ground simulation research device for near-earth space plasma-laser interaction. Background technique [0002] Plasma is a special dispersive electromagnetic medium, which has the characteristics of high energy content (free energy density is much higher than other substances) and multi-scale energy and momentum transport. Economic and scientific and technological progress has a significant impact. [0003] Space experiment is the most direct means to study the interaction between plasma environment and laser in near-Earth space. There are certain limitations, such as the high cost of space satellite detection, and it is difficult to obtain global multi-point observation data. [0004] Therefore, while extensively carrying out space on-orbit experiments, it is of great scientific value and urgent reality to establish appropriate ground simulation r...
