本文报道了几种商业化生产的超镜膜的反射率，并研究了界面粗糙度和互扩散对镜面反射率的影响。测量了平均反射率为0.95或更高的均匀反射率分布，其反射率为普通镍临界角度的3倍以上。这种高质量的涂层可以极大地提高传统的冷中子导热管的导电性，并使显着改善导热成为可能。
The reflectivities of some commercially manufactured supermirror guide coatings are reported and the effects of interfacial roughness and interdiffusion on the specular reflectivity examined. Uniform reflectivity profiles with average reflectivities of .95 or better out to three times the critical angle of ordinary Ni have been measured. Such high quality coatings can dramatically increase conventional cold neutron guide tube conductance and make possible significantly improved thermal guides.
