Expansion of laser-produced plasmas in stellarator fields

L.L. Lengyel1977年被引用 21Nuclear FusionIF 3出版社

The initial acceleration, transverse deceleration, toroidal expansion, and dynamic transition to equilibrium of laser-produced plasmoids in stellarator fields is considered. As is shown, the transverse deceleration may be subject to a Kruskal-Schwarzschild instability. The losses associated with radial drift during the toroidal expansion remain tolerable as long as the magnetic field does not fully penetrate the plasma. Further losses can be expected during the dynamic transition to equilibrium distributions, particularly at low plasma temperatures. The losses may be effectively reduced by suitable selection of the initial plasma (laser) parameters.

レーザー生成プラズモイドのステラレータ磁場中における初期加速、横方向減速、トロイダル膨張、および平衡状態への動的遷移について考察する。示されるように、横方向減速はクルスカル・シュヴァルツシルト不安定性の影響を受ける可能性がある。トロイダル膨張中の半径方向ドリフトに伴う損失は、磁場がプラズマを完全に貫通しない限り許容範囲内に留まる。さらなる損失は、特に低いプラズマ温度において、平衡分布への動的遷移中に予想される。これらの損失は、初期プラズマ(レーザー)パラメータの適切な選択により効果的に低減され得る。
