Effect of Two-Dimensional Plasma Inhomogeneity in Magnetic Island on Threshold of Parametric Excitation of Trapped Upper Hybrid Waves and Level of Anomalous Absorption in ECRH Experiments
摘要
Abstract
The phenomenon of two-dimensional localization of the upper hybrid (UH) wave in a magnetic island was discovered. It was studied how this phenomenon affects the threshold and saturation level of the absolute parametric decay instability of the extraordinary wave, as a result of which a couple of two-dimensionally localized UH waves are excited.
