Description

Technical field: [0001] The invention belongs to the field of magnetic reconnection devices, and mainly relates to a three-dimensional space forming structure of a high magnetic flux helical magnet used in a vacuum environment. Background technique: [0002] The reconnection of magnetic field lines is one of the important physical processes in space plasma. This phenomenon has been observed in solar flares and magnetospheric plasmas. The magnetic field reconnection process is accompanied by the disconnection and reconnection of the magnetic field lines, which can lead to changes in the topological shape of the magnetic field lines. Magnetic field reconnection provides an effective mechanism for rapidly converting magnetic energy into plasma kinetic energy and thermal energy. Energy conversion in processes such as solar flares, magnetospheric substorms, and sawtooth oscillations in tokamaks are considered to be closely related to magnetic field reconnection. . The solar ob...

Problems solved by technology

However, there are still many important physical problems to be solved in the research of reconnection, such as what is the trigger mechanism of reconnection? Then it is released and converted into plasma kinetic energy and thermal energy quickly and locally. At present, the laboratory magnetic field reconnection research in three-dimensional space has gradually attracted attention.

The experimental results on the early linear device have been re-emphasized, which is one of the reasons for choosing the linear magnetization device to carry out the reconnection experiment. By carefully measuring how the small-section distribution of the plasma and magnetic field parameters changes with the axial position, the local reconnection is studied. The connection between the coupling phenomenon and the overall magnetic field self-organization process and the experiments on the iso-annular device have also found that the parallel electric field has a local structure and will propagate along the ring direction, which indicates that the axisymmetric assumption was used in the toroidal device in the past to study the two Dimensional reconnection process is not comprehensive

In addition, the range of changes in plasma parameters and reconnection driving forces in current laboratory research is limited, and no systematic research has been carried out on these parameters, so it is difficult to determine the relationship between the triggering of reconnection and the driving force and plasma parameters
