Neoclassical diffusion in a helically perturbed magnetic field

J.A. Krommes, P.H. Rutherford1974年被引用 13Nuclear FusionIF 3出版社

Neoclassical particle diffusion and heat transport are discussed for tokamak-like devices in the "banana" regime (νeff < ωb) with helically perturbed magnetic fields such as might be produced by kink-like instabilities. The diffusion coefficient scales as D ∼(ν1/ν) ξ2 Dpl where ξ is related to the amplitude of the perturbation and ν is the collision frequency. For typical experimental parameters and sufficiently low collision frequency, transport is moderately enhanced over the axisymmetric result.

「バナナ」領域(νeff < ωb)にあるトカマク類似装置における新古典粒子拡散および熱輸送について、キンク状不安定性によって生成されるような螺旋摂動磁場を伴う場合を議論する。拡散係数は D ∼(ν1/ν) ξ2 Dpl のようにスケールする。ここで ξ は摂動の振幅に関連し、ν は衝突周波数である。典型的な実験パラメータおよび十分に低い衝突周波数に対して、輸送は軸対称の場合の結果よりも適度に増強される。
