阻抗匹配靶制备及靶参数精密测量

Fabrication and Measurement of Impedance Match Target

摘要: 通过精密轧机轧制Al、Cu、Au等高纯金属箔片，采用精密微装配技术获得应用于激光状态方程实验所需的阻抗匹配靶。运用台阶仪和白光干涉仪分别对阻抗匹配靶进行靶参数精密测量。在“神光Ⅱ”上进行阻抗匹配的实验打靶，获得了相关靶型的实验图像。

Abstract: The Al, Cu and Au thin foils were rolled with the precision rolling mill, and the rolled metal foils were fabricated as impedance match targets used in the laser equation of state experiments by the assembly. The target parameters were measured by α-step500 and NT1100. The fabricated impedance match targets were used in ‘SGⅡ’. Good images were obtained in experiment.
