Thermal quench in tokamaks

A.V. Nedospasov2008年被引用 8Nuclear FusionIF 3出版社

A model of thermal quench in tokamaks is proposed, which presumes that the duration of energy release on the walls (thermal quench) is defined by the outflow of plasma from the core. The motion of plasma in the SOL at the stage of thermal quench is regulated by the same processes of anomalous transport which exist in steady-state modes. An approximate formula is derived, which relates the duration of thermal quench to the parameters of facilities and to the characteristics of plasma. The obtained results are compared with experimental data.

トカマクにおける熱クエンチのモデルを提案する。このモデルは、壁へのエネルギー放出の持続時間(熱クエンチ)が、コアからのプラズマ流出によって決定されると仮定する。熱クエンチ段階におけるSOL内のプラズマ運動は、定常状態モードに存在するものと同じ異常輸送過程によって支配される。熱クエンチの持続時間を装置パラメータおよびプラズマ特性に関連付ける近似式を導出する。得られた結果は実験データと比較される。
