在最近的EAST实验中,通过同时注入电子回旋加速器(EC)和低杂波(L H)波,可以将中心的电子温度提高到9.7keV。在如此强的核心电子加热下,相对论效应可能在等离子体与波的相互作用中起到重要作用。为了探索EAST上EC波和LH波之间协同的相对论效应,用射线追踪/Fokker-Planck方法模拟了中心电子温度为9.7keV的典型放电的电子加热。结果表明,相对论效应可以使EC波的能量沉积在等离子体核更深的位置,在那里EC波和LH波发生协同作用,增强了LH波的吸收。结果,可以获得较高的中心电子温度。
In recent experiments on EAST, the electron temperature at the center can be raised to 9.7 keV by injecting electron cyclotron (EC) and lower hybrid (LH) waves simultaneously. With such strong core electron heating, the relativistic effect could play an important role in the interactions between the plasma and waves. In order to explore the relativistic effect on synergy between the EC and LH waves on EAST, ray-tracing/Fokker–Planck simulations are conducted to investigate electron heating for a typical discharge with a center electron temperature of 9.7 keV. It is found that the relativistic effect can cause the EC wave to deposit its power deeper in the plasma core, where the synergy between the EC and LH waves occurs and enhances the absorption of the LH waves. As a result, a high center electron temperature can be achieved.
