Description

technical field [0001] The invention relates to a simulation device for a near-earth space plasma environment, in particular to a space plasma parameter diagnosis device based on a four-degree-of-freedom motion mechanism. Background technique [0002] In order to study the basic physical process of plasma in near-Earth space, a common method is to construct a large-scale experimental device to conduct simulation research on the ground. In the space plasma environment simulation device, plasma diagnosis plays a very important role. Only by obtaining large-scale, high-resolution, and high-precision plasma parameter diagnosis can we accurately characterize the plasma state and study related physical phenomena. Among many diagnostic methods, probe diagnosis is the most basic diagnostic method, which can diagnose physical quantities such as plasma density, temperature, and magnetic induction intensity, and has high spatial resolution. However, in the near-Earth space plasma envi...

In addition, a large number of magnet coils are installed in the near-Earth space plasma simulation device, and their motion support mechanisms are connected to the vacuum chamber. The electromagnetic force of the magnet coils will be transmitted to the vacuum chamber through the motion support mechanism, resulting in deformation of the vacuum chamber.
