Generation of localized lower-hybrid current drive by temperature perturbations

Despite high demonstrated efficiency, lower-hybrid current drive (LHCD) has not been considered localized enough for neoclassical tearing mode (NTM) stabilization in tokamaks. This assessment must be reconsidered in view of the radiofrequency current condensation effect. We show that an island with a central hot spot induces significant localization of LHCD. Furthermore, in steady state tokamaks where a significant amount of current is provided by LHCD, passive stabilization of NTMs may occur automatically, particularly as islands become large, without requiring precise aiming of the wave power.

高い実証効率にもかかわらず、低混成波電流駆動(LHCD)は、トカマクにおける新古典テアリングモード(NTM)の安定化には十分な局在性を有するとは考えられてこなかった。この評価は、高周波電流凝縮効果に鑑みて再考されなければならない。我々は、中心に高温スポットを有する磁気島がLHCDの顕著な局在化を誘起することを示す。さらに、LHCDによってかなりの電流が供給される定常トカマクにおいては、特に磁気島が大きくなるにつれて、波動パワーの精密な位置合わせを必要とせずに、NTMの受動的安定化が自動的に生じ得る。
