New plastic nanostructured foil targets interacting with an ultra-high intensity laser pulse are investigated by performing particle-in-cell simulations. The thickness of the ultra-thin planar and nanostructured foil target is in the range of tens of nanometers. Complementary numerical simulations which use the finite-difference time-domain method without considering plasma generation have been performed. The laser pulse has the parameters of the two 10 PW lasers from ELI-NP. The circularly polarized laser pulse has the twice intensity of the linearly polarized (LP) laser pulse. We show a strong dependence of the maximum proton energy on the nanospheres diameter. But, the carbon ion maximum energy varies very weak with the nanospheres diameter. We prove that the acceleration regime of the protons is a combination of the radiation pressure acceleration and target normal sheath acceleration regimes. The carbon ions experience the target normal sheath acceleration. This study is a ...

模拟超高强度激光脉冲与超薄纳米结构箔靶的相互作用

通过执行细胞内颗粒模拟研究了与超高强度激光脉冲相互作用的新型塑料纳米结构箔靶。超薄平面和纳米结构箔靶的厚度在几十纳米的范围内。进行了使用有限差分时域方法而不考虑等离子体产生的补充数值模拟。激光脉冲具有ELI-NP的两个10 PW激光器的参数。圆偏振激光脉冲的强度是线性偏振（LP）激光脉冲的两倍。我们显示最大质子能量对纳米球直径的强烈依赖性。但是，碳离子的最大能量随纳米球直径的变化非常微弱。我们证明了质子的加速状态是辐射压力加速和目标法向鞘层加速状态的组合。碳离子经历目标正常护套加速。这项研究是...
