在高温等离子体中,电子回旋共振频率ω_(ce)附近微波束的能量可以通过线性耦合机制转换给等离子体波,然后阻尼为粒子的动能。这是一种有前途的加热方法。在典型托卡马克装置中,电子回旋共振频率范围是20—200千兆赫,即处于毫米波或亚毫米波段。电子回旋共振加热的优点主要是采用准光学方式传播与耦合时可以保证等离子体不受杂质污染;微波至
In a high-temperature plasma, the energy of the microwave beam near the electron cyclotron resonance frequency ω_ (ce) can be converted to a plasma wave by a linear coupling mechanism and then damped to the kinetic energy of the particle. This is a promising method of heating. In a typical tokamak device, the electron cyclotron resonance frequency range is 20-200 gigahertz, ie in the millimeter wave or submillimeter band. The advantages of electron cyclotron resonance heating are mainly that the plasma is not contaminated with impurities when it is transmitted and coupled in a quasi-optical manner; microwave to
