在这里，我们报告了准光学代码PAraxial RAy DEscription（2019 Phys. Plasmas 26 072112）的升级，以介绍电子回旋共振加热的相对论效应和聚变DEMO反应堆上的电流驱动，例如JA-DEMO，其中电子温度足够高（几乎35 keV）。在充分考虑相对论效应的基础上，发现由于相对论下移高次谐波共振处空间分布吸收的污染，许多托卡马克装置采用的外部发射方式不适合JA-DEMO的局域加热。建议采用顶部发射来避免这个问题，并且表明顶部发射可以在不降低电流驱动效率的情况下改善加热的局部化。
Here we report on the upgrade of the quasioptical code PAraxial RAy DEscription (2019 Phys. Plasmas 26 072112) to introduce the relativistic effect for electron cyclotron resonance heating and current drive on fusion DEMO reactors, eg JA-DEMO, where the electron temperature is sufficiently high (almost 35 keV). By fully considering the relativistic effect, it is found that the outside launch used in many tokamaks is not suitable for localized heating in JA-DEMOdue to the contamination of spatially widespread absorption at relativistically down-shifted higher-harmonic resonance. It is proposed to adopt a top launch to avoid this issue, and is shown that top launch can improve the localization of the heating without degrading the current drive efficiency.
