Super-intense quasi-neutral proton beams interacting with plasma: a numerical investigation

H. Ruhl, T. Cowan, J. Dahlburg, P. Parks, R. Stephens2004年被引用 14Nuclear FusionIF 3出版社

Due to the unique properties of the recently discovered sheath laser-ion source the investigation of super-intense, quasi-neutral ion beams interacting with plasma has become of substantial interest. Novel experiments in parameter regimes that bear relevance for future ion based fast ignition concepts can be envisioned. Simulations in three spatial dimensions of protons, charge and current neutralized by co-moving electrons, interacting with a low density plasma are presented. Quasi-neutral beam propagation and normalized proton beam momentum growth are discussed.

近年発見されたシースレーザーイオン源の独特な特性により、高強度の準中性イオンビームとプラズマとの相互作用の研究が大きな関心を集めている。将来のイオンを用いた高速点火概念に関連するパラメータ領域における新規実験が構想され得る。共移動電子によって電荷および電流が中和された陽子が、低密度プラズマと相互作用する三次元空間シミュレーションを示す。準中性ビーム伝播および規格化陽子ビーム運動量の成長について議論する。
