从激光加速到激光离子加速器

Development and prospects of laser ion accelerators

  • 摘要: 高能离子束在基础研究、材料学、生物学及医学等诸多领域有着重要价值和广泛应用,其产生方法也受到了越来越多的关注。激光等离子体相互作用能够产生比常规射频加速器高三个量级的加速电场,由此可以建造占地小、成本低、峰值流强高的新型加速器。文章介绍了激光离子加速的基本物理概念及实验进展,并对激光离子加速器的工程设计及应用前景进行了简介。

     

    Abstract: High-energy ion beams are of great value and are widely used in many fields such as basic research, materials science, biology, and medicine; for this reason, their generation methods are receiving increasing attention. Laser plasma interaction can generate an accelerating electric field three orders of magnitude higher than that of a conventional radio frequency accelerator, which allows the construction of new compact accelerators with low cost and high peak flow intensity. This paper introduces the basic physical concepts and experimental progress of laser ion acceleration, and gives an overview of the engineering design and application prospects of laser ion accelerators.
