Testing the first neutron mirror flipper

摘要

The first neutron mirror flipper built as a magnetic Co_(70)Fe_(30) (71.1 nm) layer on a non-magnetic periodic multilayer {NiMo(6.96 nm)/Ti(6.17 nm)} × 20 was tested. Its efficiency at the Bragg peak was found to exceed 0.966. Thus, the possibility of producing neutron mirror spin turners, including π/2- and π-turners (flippers), was experimentally demonstrated.
