An electrodynamical model for the ion behaviour in the final plasma focus stages

V Zambreanu, C M Doloc1992年Plasma Physics and Controlled FusionIF 2.2出版社

Plasma focus devices (PFDs) are strong sources of fusion neutrons but the problem of which interactions are responsible for the fusion reactions is still open since neither of the proposed theoretical models has been confirmed experimentally. The authors propose a model for the trajectories of the deuteron ions in a configuration of self-consistent electromagnetic fields starting from an empirical plasma model which describes the plasma focus collapse and column phases. The proposed model is only electrodynamical under the assumption of a uniform current density and an infinite length of the plasma column, not taking into account the fluid characteristics of the plasma.

プラズマフォーカス装置(PFD)は強力な核融合中性子源であるが、どの相互作用が核融合反応の原因であるかという問題は、提案された理論モデルのいずれも実験的に確認されていないため、依然として未解決のままである。著者らは、プラズマフォーカスの収束段階および柱状段階を記述する経験的プラズマモデルから出発して、自己無撞着な電磁場の配位における重陽子イオンの軌道モデルを提案する。提案されたモデルは、プラズマ柱の一様な電流密度と無限の長さを仮定した純粋に電気力学的なものであり、プラズマの流体特性は考慮していない。
