Abstract

The possibility of local measurement of the fluctuation level of the radial plasma velocity using equatorial enhanced scattering of a narrow microwave beam in the upper hybrid resonance in internal regions of tokamak plasma is demonstrated. Restrictions of the proposed method at the plasma periphery where the density fluctuation amplitude increases and small-angle scattering of microwaves by the fluctuations along the path to the upper hybrid resonance and back becomes significant are clarified.

利用赤道增强散射对FT-2托卡马克中径向血浆速度波动的局部测量

摘要

证明了在托卡马克等离子体内部区域中的上部混合共振中使用窄微波束的赤道增强散射来局部测量径向等离子体速度的波动水平的可能性。阐明了所提出的方法在等离子体外围的局限性，在等离子体外围，密度波动幅度增加，并且由于沿着到上混合共振和返回的路径的波动而引起的微波的小角度散射变得显着。
