摘要
在激光血浆相互作用的离子加速上的一些笔记和评价被给,特别地为吃惊的含意,鞘并且可伸缩。一个简单模型被吃惊和鞘的联合为离子加速建议。在最大的离子精力和激光参数之间的获得的可伸缩的关系(力量,脉搏持续时间)也血浆参数(血浆密度),例如 E <SUB >离子,最大</SUB> P <SUP>7/12</SUP><SUB > L </SUB>, E <SUB >离子,最大</SUB>τ
<SUP>1/3</SUP><SUB > L </SUB>,和 E <SUB >离子,最大</SUB> n <SUP>2/3</SUP><SUB > e </SUB>,与以前的工作相比。模型和结果的一些缺乏和含意被讨论。
Some notes and comments on ion acceleration in laser-plasma interaction is given, in particular for the implication of shock, sheath and sealing. A simple model is proposed for ion acceleration by the combination of shock and sheath. The obtained scaling relations between the maximum ion energy and laser parameters (power, pulse duration) as well plasma parameter (plasma density)for example α PL 7/12 Eion,max α TL1/3 and Eion,max α ne2/3,are compared to the previous works. Some deficiencies and implications of model and results are discussed.
