由于离子束固有的单能性质，用高强度短脉冲激光辐照薄靶后加速的离子的辐射压力加速（RPA）机制最近受到了很多关注，能量缩放预计与激光强度成比例[1，2]。在本文中，2D Osiris PIC模拟使用一个现实的双子脉冲与纳米尺度的目标相互作用进行了讨论。结果显示，圆偏振和目标厚度在访问RPA制度的重要性。
The radiation pressure acceleration (RPA) regime for ions accelerated after irradiating thin targets with high intensity short pulse lasers has recently been given a lot of attention due to the inherent monoenergetic nature of the ion beam, with energy scaling predicted to be proportional to the intensity of the laser [1,2] . In this paper, 2D Osiris PIC simulations using a realistic Gemini pulse interacting with nanometer scale targets will be discussed. Results showing the importance of circular polarisation and target thickness in accessing the RPA regime will be presented.
