Abstract
Neutron optical devices, such as neutron guides, apply mirrors where m ultiple total reflections of neutrons takes place. Materials more ligh t and flexible than glass have never been used as a substrate of the n eutron mirrors. The present work deals with neutron reflectivity measu rements performed for three nickel mirrors. While one of them is a gla ss plate coated with a NiCr film, the other two mirrors are on plexigl as substrates coated by either NiCr or Ni-58 films. The incident beam covered a neutron wavelength range from 0.05-0.4 nm. The results of th e present measurements are in favour of the idea of using acrylic glas s as a substrate for nickel mirrors.
