KT-5B托卡马克等离子体中剪切Alfven波的激发特性

EXCITATION OF SHEAR ALFVEN WAVES IN KT-5B TOKAMAK

本文报道最近在KT-5B托卡马克装置上进行Alfven波激发特性研究的实验结果。结果表明:Alfven波存在比较宽的激发区域,耦合强度随等离子体电流、纵向磁场的上升而增强。观测到温度阈值效应,并初步得到表面静电波的实验证据。

In this paper, the experimental results of Alfven wave excitation in KT-5B Tokamak are presented. The results show that there is a quite broad excitation region for shear Alfven waves, the wave energy coupling indicated by the antenna loadings increase as the plasma current and toroidal magnetic field increase. The electron temperature threshold effects and the preliminary evidence of the surface electrostatic wave are observed.
