超短超强激光与等离子体相互作用中质子发射一些研究进展

Some Development of Proton Generated Ultra-short and Ultra-intense Laser Plasma Interaction

超短超强激光与等离子体相互作用中得到的高能质子在质子成像、粒子加速、诊断超短超强激光与等离子体相互作用的物理过程、“快点火”和治疗癌症等方面有一定的应用。使得对超短超强激光与等离子体相互作用得到的高能质子的研究成为目前的研究热点。文章综述了产生质子的两种主要加速机制以及在不同实验条件下超短超强激光与等离子体相互作用过程中得到质子的能量、角分布、产额以及相关的原理。

During the interaction of ultra-short and ultra-intense laser with plasma, application of energetic protons generated by this interaction are proton imaging,compact particle accelerators,diagnosis the interaction of ultra-short and ultra-intense pulse laser with plasma, ＂fast ignitor＂and proton cancer therapy etc.Now the research of energetic proton is one of the hotspots.Here the author sums up two main acceleration mechanisms of proton, proton energy,angular distribution,proton yields and correlative principle in different experimental conditions.
