| 摘 要： | 分别使用频率为34.34GHz和20.1GHz的迴旋管系统从外侧和顶端注入微波,对CT-6B托卡马克等离子体加热,均观察到明显的加热效果。分析表明两者有不同的加热机制。前者主要属于O模的共振加热;后者为X模的非共振-高密度加热,其机制可能来源于高密度截止层附近的非线性现象。在两种实验中,都观测到称为二次加热的非线性加热现象。它们可能分别来自不同的物理机制。

| Abstract: | Obvious heating effects have been observed in RF heating experiments on CT-6B tokamak, in which microwave beams of frequencies 34.34 GHz and 20.1 GHz generated by two gyrotron systems were launched from top and outside of the device, respectively. It is shown that these heating effects arise becouse of the different heating mechanisms. The former is due mainly to the resonance heating of O mode. The latter belongs to down shift-over dense heating. Its heating mechanism may be the nonlinear phenomena occuring near the high density cut off layer of X mode. A kind of nonlinear heating phenomena (secondary heating) has been observed in two experiments, which may come from the different physical mechanisms. |
