Description

technical field [0001] The invention belongs to the technical field of electromagnetic launch, and in particular relates to an electromagnetic acceleration and deceleration two-stage electromagnetic injection launch device and method of an integrated track. Background technique [0002] During the operation of the tokamak nuclear fusion device, the plasma of hundreds of millions of degrees is confined in the vacuum chamber by the strong magnetic field. However, due to various physical instability and engineering technology and other factors, sometimes the plasma will lose the magnetic confinement, and the plasma will lose its magnetic confinement in a very short time. rupture occurs within the time period. The unconfined and ruptured plasma will cause serious damage to the inner wall of the device if it is not controlled in time and effectively. Therefore, in order to reduce the harm caused by the rupture of the plasma, it is necessary to inject ice pellets (commonly known ...

AI Technical Summary

Problems solved by technology

The flight speed of ice pellets driven by high-pressure gas can only reach a maximum of 600m / s. The time from when the rupture warning device sends out an early warning signal to trigger the rupture mitigation device to when the ice pellets are injected into the plasma by high-pressure gas may be longer than 30ms, which cannot meet the requirements for rupture mitigation. time requirements

Moreover, due to the low speed of the ice pellets, the injected ice pellets do not penetrate the outer layer of the plasma to reach the center of the plasma, which cannot effectively alleviate the occurrence of plasma rupture.
