Experiments at the LANL Trident facility demonstrated the production of monoenergetic ion beams from the interaction of an ultraintense laser with a target comprising a heavy ion substrate and thin layer of light ions. An analytic model is obtained that predicts how the mean energy and quality of monoenergetic ion beams and the energy of substrate ions vary with substrate material and light-ion layer composition and thickness. Dimensionless parameters controlling the dynamics are derived and the model is validated with particle-in-cell simulations and experimental data.
在洛斯阿拉莫斯国家实验室的三叉戟设施所进行的实验表明，利用超强激光与由重离子基体和轻离子薄层组成的靶相互作用可产生单能离子束。得到了一个分析模型，该模型预测了单能离子束的平均能量和品质以及基体离子的能量如何随基体材料、轻离子层组成和厚度而变化。推导了控制动力学的无量纲参数，并用粒子模拟和实验数据对该模型进行了验证。
