Structure of low-frequency oscillations during the disruptive instability in the TFR tokamak

The behaviour of the m = 0, n = 0; m = 1, n = 1 and m = 2, n = 1 low-frequency oscillations has been studied within the framework of the current disruption in TFR. The experimental observations show the fundamental role of the m = 2 mode in triggering and growth of the instability, the existence of two m = 1 modes near the q = 1 surface, one of which is directly connected with the m = 2 mode.

m = 0、n = 0、m = 1、n = 1、およびm = 2、n = 1の低周波振動の挙動が、TFRにおける電流崩壊の枠組みの中で研究された。実験観測により、m = 2モードが不安定性の誘発と成長において基本的な役割を果たすこと、またq = 1表面付近に2つのm = 1モードが存在し、そのうちの1つがm = 2モードと直接関連していることが示された。
