达卡镜-超冷中子的几乎无损的指南
Replika Mirrors - Nearly Loss-Free Guides For Ultracold Neutrons
摘要：
研究了用一种称为{ \sc <$ka}的专用技术制备的超冷中子（UCN）波导的反射率。导轨由镍制成，表面质量是从玻璃层复制的。这导致表面粗糙度小于10 μ m。反射率测量为99.9%或更高。这些指南可用于目前或未来的UCN源，将UCN远距离运输到相应的实验，而不会有重大损失。
英文摘要：
The reflectivity of ultracold neutron (UCN) guides produced with a dedicated technique called {\sc Replika} has been studied. The guides are made of nickel, where the surface quality was copied from a glass layer. This results in a surface roughness smaller than 10 Å. The reflectivity was measured to be 99.9% or higher. Those guides can be used at present or future UCN sources to transport UCN over long distances to the respective experiments without significant losses.
