| 摘 要： | 在周期多层膜基础上，采用随机数方法找到适当的非周期膜系， 极大地提高了反射光通量，并给出了整体设计步骤。模拟计算结果表明非周期多层膜能扩展带宽和提高反射率积分值。在12.4～20.1nm波段内，最佳非周期多层膜与峰值在中心波长λ=16.25nm处 的周期多层膜相比，理论积分反射率提高了75%。多个多层膜组成系统的积分强度无明显改善。

| Abstract: | A random method used for improving light throughput of a soft X ray multilayer mirror has been developed. It is demon strated that layer thickness disorder yields band broadening and increased integrated reflectivity,and achieved 75% increase in integrated reflctivity in the 12.4～20.1nm spectral range with respect to periodic multilayer with its first Bragg peak in the center of that range． |

| Keywords: | disordered multilayer soft X ray random number integrated reflectivity |
