ASDEX 中电流密度分布随时间演变的测量表明,较低的混合电流驱动会导致更宽的分布,其中 q 从 qapprox 开始增加。 1 位于等离子体中心区域。同时,观察到电子温度达到峰值,从而证明较低混合驱动的电流分布与经典电导率分布脱钩。
Measurements of the time evolution of the current-density distribution in ASDEX show that lower-hybrid current drive leads to broader profiles, whereby q increases from qapprox. 1 in the plasma central region. Simultaneously, the electron temperature is observed to peak, thus demonstrating that the lower-hybrid--driven current distribution is decoupled from the classical conductivity profile.
