The two time-scales of the sawteeth precursors

A.L.M. Rogister, R. Singh, A. Kaleck1989年被引用 8Nuclear FusionIF 3出版社

For current profiles with a slope discontinuity at ∊2 close to ∊1[q(∊1) = 1] and a small shear 1(∊1), the jump of the derivative of the magnetohydrodynamic (MHD) solution across the singular q = 1 layer is of the form ∊ is the finite inverse aspect ratio, μ ≡ 1∊1/8(∊2–∊1) measures the ratio of the two small parameters. The growth rate of the sawtooth trigger can accordingly pass from resistive values either negative and finite or positive) to MHD values for slight variations of either 1 or (∊2–∊1)/∊1. The above profile properties have been observed in sawtoothing TEXTOR discharges.

勾配不連続性を有する電流分布(∊2が∊1[q(∊1)=1]に近い)と小さなシア1(∊1)に対して、特異なq=1層を横切る電磁流体力学(MHD)解の導関数のジャンプは次の形をとる:∊は有限の逆アスペクトル比であり、μ≡1∊1/8(∊2–∊1)は2つの小さなパラメータの比を表す。鋸歯状振動のトリガーの成長率は、それに応じて、抵抗性の値(負かつ有限、または正)から、1または(∊2–∊1)/∊1のわずかな変動に対してMHDの値へと移行しうる。上記の分布特性は、鋸歯状振動を伴うTEXTOR放電において観測されている。
