Neoclassical transport in a fast-wave-heated bumpy torus

Neoclassical transport coefficients for ions in the core plasma of a bumpy torus are calculated analytically in the intermediate collisionality 'plateau' regime of operation, including the effects of a distortion in the ion velocity distribution function due to applied fast-wave heating. Two new transport coefficients have been identified in this regime which are proportional to the radial gradient of the magnetic field and the radial gradient of the heating-wave electric field. The effects of heating at both the fundamental and the second harmonic of the ion gyrofrequency are considered. These coefficients are incorporated into a spatially averaged fluid transport model which simulates majority ion heating. Self-consistent power balance solutions for an ion-heated bumpy torus are obtained by using these coefficients and are compared with the solutions using ion transport coefficients which ignore wave-heating modifications. A major conclusion from this work is that the introduction of fast-wave heating in a bumpy torus has no deleterious effects on the neoclassical transport of particles or energy.

バンプトーラスのコアプラズマにおけるイオンの新古典輸送係数を、中間衝突領域である「プラトー」運転領域において解析的に計算し、印加された高速波加熱によるイオン速度分布関数の歪みの影響を含めた。この領域において、磁場の動径勾配と加熱波の電場の動径勾配に比例する2つの新しい輸送係数が同定された。イオンジャイロ周波数の基本波および第二高調波での加熱の効果を考察した。これらの係数を、空間平均化された流体モデルに組み込み、主要イオン加熱をシミュレートした。これらの係数を用いて自己無撞着なパワーバランス解を得て、波動加熱による修正を無視したイオン輸送係数を用いた解と比較した。この研究の主要な結論は、バンプトーラスにおける高速波加熱の導入は、粒子またはエネルギーの新古典輸送に悪影響を及ぼさないということである。
