Description

technical field [0001] The invention belongs to the technical field of active control, and in particular relates to an electronic cyclotron wave-based real-time control system and method of an Alfven model. [0002] technical background [0003] There are a large number of high-energy particles in magnetically confined plasma, such as fast electrons, fast ions, and alpha particles. The interaction between high-energy particles and Alfven waves can excite different types of Alfven modes, mainly including Alfven eigenmodes and high-energy particle modes. Evidence shows that these instabilities are very likely to destroy the ring symmetry and enhance the transport, resulting in the loss of a large number of high-energy particles, and even burning the first wall of the magnetic confinement device in severe cases. This is extremely unfavorable to maintaining nuclear fusion reaction, obtaining high fusion gain and safe operation of magnetic confinement fusion devices. In addition...

Problems solved by technology

However, except for the American DIII-D device which successfully realized the active control of the Alfvén by the neutral beam, there is no other device in the world capable of real-time control of the Alfvén mode.

In order to avoid the decrease of plasma confinement performance caused by the Alfvén mode, the present invention proposes a method based on electron cyclotron resonance heating / current drive combined with high spatiotemporal resolution real-time measurement technology, fast intelligent identification technology and precise controllable radio frequency wave injection technology to realize Alfén mode real-time control method
