Paper Abstract

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.
