摘要
数值计算了激光直接驱动铝飞片空腔靶模型.结果表明:激光和靶结构参数对飞片状态和靶中冲击波特性的影响很大;如果激光和靶结构参数选择合理的话,可以近似实现飞片与靶的对称碰撞,而且靶中冲击波的稳定区有一定的空间宽度;因而,选择适当厚度的三台阶靶。
We present the numerical calculation of the model of aluminum flyer\|vacuum\|target with high power laser driving.The results show that the parameters of laser and target's structure have great effects on the state of flyer and the character of shock\|waves in the target.If we select the parameters of laser and target's structure reasonably, we can achieve approximately symmetric impact between flyer and target;moreover,the shock\|wave in the target has a stable area with a certain spatial width.So,if we choose the three\|step\|target with a suitable thickness,we can approach an absolute measurement of equation\|of\|state.
