A simple dynamical model of edge localized mode phenomena

V B Lebedev, P H Diamond, M M Medvedev, P N Yushmanov, B A Carreras1996年Plasma Physics and Controlled FusionIF 2.2出版社

A dynamical model of edge-localized mode (ELM) phenomena is presented. It combines the paradigms of the L - H transition mediated by electric field shear induced suppression and generation with a simplified description of MHD instability and with a transport analysis of the plasma edge. In the parameter regime characteristic of an H-mode plasma, the model exhibits a transition to stationary relaxation oscillations (i.e. stable limit cycle behaviour) corresponding to ELMs. The dependence of ELM frequency, amplitude etc on the heating power and other control parameters is studied.

周辺局在モード(ELM)現象の動的モデルを提示する。このモデルは、電場シアによる抑制と生成を媒介とするL-H遷移のパラダイムと、MHD不安定性の簡略化した記述、およびプラズマ周辺部の輸送解析を組み合わせたものである。Hモードに特徴的なパラメータ領域において、このモデルはELMに対応する定常緩和振動(すなわち安定なリミットサイクル挙動)への遷移を示す。ELM周波数、振幅などの加熱パワーおよびその他の制御パラメータへの依存性について研究する。
