提出了一种利用激光脉冲（~ 1021 W/cm ~ 2）辐照锥形靶将碳离子束加速到高能量和高密度的方案，并采用粒子模拟方法进行了研究。激光脉冲被圆锥聚焦，并向前驱动位于圆锥尖端的金属箔。在工作的过程中，获得最好的结果，采用目标配置相结合的低Z锥与多物种箔横向形状匹配的激光强度分布。
A scheme in which carbon ion bunches are accelerated to a high energy and density by a laser pulse (∼1021 W/cm2) irradiating cone targets is proposed and investigated using particle-in-cell simulations. The laser pulse is focused by the cone and drives forward an ultrathin foil located at the cone's tip. In the course of the work, best results were obtained employing target configurations combining a low-Z cone with a multispecies foil transversely shaped to match the laser intensity profile.
