在给定等离子体密度分布下,从电子、离子的能量方程出发,根据不同运行模式下等离子体的热传导率不同,分别求出了中心负剪切模式,常规剪切H模式和L模式下的等离子体温度分布,然后通过求解波迹方程与相对论情况下的Fokker-Planck方程,分别计算了这些模式下的电子回旋波电流驱动和波功率沉积.得到在中心负剪切下,驱动电流最大,驱动效率最高,功率沉积和电流分布区间跨度大;在常规剪切H模式下,驱动电流较小,分布区间跨度比较窄,驱动效率相对较低;在常规剪切L模式,驱动电流效率最低,分布区间跨度也非常集中.
Under a given plasma density distribution, starting from the energy equations of electrons and ions, according to the different thermal conductivity of the plasma in different operating modes, the center negative shear mode, the normal shear mode H and the L mode Plasma temperature distribution, and then by solving the wave equation and the Fokker-Planck equation under the relativistic conditions, the electron gyro wave current driving and the wave power deposition are calculated respectively in these modes. Under the negative center shear, the driving current is the maximum, In conventional shearing H mode, the driving current is smaller and the span of the distribution interval is narrower and the driving efficiency is relatively lower. In the conventional shearing L mode, the driving current has the lowest efficiency, Span distribution is also very concentrated.
