Lower hybrid ion heating in the FT-2 tokamak

V.N. Budnikov1991年被引用 10Nuclear FusionIF 3出版社

The paper generalizes the results of plasma heating experiments in the FT-2 tokamak. It is shown that the generation of fast ions is associated not with the region of linear transformation, nLH, but with the parametric decay region, nd ≃ (0.3-0.5)nLH. In the narrow zone nd, strongly slowed down waves were observed (by a method relying on enhanced scattering of microwave radiation) at a frequency of about 0.7f0 (where f0 is the frequency of the heating radiation); these waves had a narrow spectrum with a width of a few megahertz. As the plasma density increases, the decay region is shifted towards the edge, but it remains 'attached', for all practical purposes, to one local density. This process helps to explain the central heating of the main ion component, the generation of fast ions at the edge, and the switching off of the interaction between the lower hybrid wave and the electrons, which stops current drive.

本論文は、FT-2トカマクにおけるプラズマ加熱実験の結果を一般化するものである。高速イオンの生成は、線形変換領域nLHではなく、パラメトリック崩壊領域nd ≃ (0.3-0.5)nLHと関連することが示されている。狭い領域ndにおいて、強く減速された波が、マイクロ波放射の増強散乱に依存する手法により、約0.7f0の周波数(ここでf0は加熱放射の周波数)で観測された。これらの波は、数メガヘルツの幅を持つ狭いスペクトルを有していた。プラズマ密度が増加するにつれて、崩壊領域は端部に向かってシフトするが、実用上は単一の局所密度に「付着」したままである。この過程は、主イオン成分の中心加熱、端部における高速イオンの生成、および電流駆動を停止させる低混成波と電子との相互作用の遮断を説明するのに役立つ。
