摘要
从理论上论证了利用平板靶X射线激光两个输出端光强对称的特性来测量X射线多层膜镜反射率的测量方法.针对实验布局中等离子体对X射线激光吸收可能造成测量误差的情况,以保证测量结果千分之一的精确度为基准,从理论上计算获得该方法对不同波长X射线激光的实验布局要求.并依此要求对制得的Mo/Si、Mo/Mg镜的反射率进行了实验测量.
A novel way of measuring the reflectivity of multilayer was proposed. Utilizing the symmetrical output of the X-ray laser in slab laser-plasma, the reflectivity could be conveniently obtained in this way. It was also given the setup parameters by calculation according to the demand of precise considering the absorption of X-ray laser by plasma. Under which an experiment of measuring the reflectivity of Mo/Si and Mo/Mg was carried out.
