摘要

我们介绍了在桑迪亚国家实验室100太瓦设备内进行的激光目标相互作用实验的结果。25μm厚铜箔的K-alpha图像显示，K-alpha光斑在垂直和水平方向上的平均直径为~ 70±10μm，指向误差小于50μm。2欧米茄光学探针脉冲阴影成像显示了自发射的前表面等离子体生长和横向焦结构。沿铜箔后方法线排列的放射性致变色膜(RCF)显示质子能量的平均峰值为8±2 MeV。

Commissioning experiments on the 100 TW Sandia laser

We present results from laser-target interaction experiments performed within the 100 TW facility at Sandia National Laboratory. A series of K-alpha images of 25μm thick copper foils reveal an average K-alpha spot diameter of ∼70±10μm and a pointing error of less than 50μm in both the vertical and horizontal directions. 2 omega optical probe pulse shadowgraphy images show front surface plasma growth and transverse focal structure from self-emission. Stacks of radiochromic film (RCF) positioned along the rear normal to the Cu foil indicate an average peak proton energy of 8±2 MeV.
