A method for efficient laser acceleration of heavy ions by electrostatic shock is investigated using particle-in-cell (PIC) simulation and analytical modeling. When a small number of heavy ions are mixed with light ions, the heavy ions can be accelerated to the same velocity as the light ions so that they gain much higher energy because of their large mass. Accordingly, a sandwich target design with a thin compound ion layer between two light-ion layers and a micro-structured target design are proposed for obtaining monoenergetic heavy-ion beams.
利用粒子模拟(PIC)和解析建模方法,研究了一种通过静电激波实现重离子高效激光加速的方法。当少量重离子与轻离子混合时,重离子可被加速至与轻离子相同的速度,从而因其较大的质量而获得高得多的能量。因此,提出了一种在两个轻离子层之间夹有薄复合离子层的夹层靶设计以及一种微结构靶设计,以获得单能重离子束。
