摘要

本文研究了激光辐射压驱动的运动电场中加速质子的相关问题.当超短超强激光脉冲与处在背景等离子体前方的薄固体平靶相互作用时

在激光辐射压的作用下

在固体靶后部形成一个电子层-离子层组成的双层结构.在激光的不断推进下

双层结构在背景等离子体里以一定速度传播

可以看成运动在背景等离子体中的电场.这样

在背景等离子体中的质子被这个运动电场捕获并能加速到很高的能量.我们通过二维PIC模拟方法研究了质子加速的相关问题.研究结果表明

被加速质子的最大能量达到20GeV.同时

我们还研究了质子加速与固体靶厚度和背景等离子体密度之间的关系

通过二维PIC模拟给出了一些优化的参数.

Abstract

Numerical optimization of protons acceleration by laser radiation pressure driving plasma double layer is investigated by means of two dimensional particle-in-cell simulation.When an ultraintense laser interacting with a solid foil with backside underdense plasma

the plasma protons can be reflected by radiation pressure driving electron-ion double layer electric field and can be accelerated to high energies.The dependence of the efficiency of proton acceleration on the foil target thickness and backside plasma density are examined in detail and the optimal parameters are obtained.
