Some of the best neutron supermirrors currently in production are made of alternating layers of nickel and titanium, with carbon added to the Ni to eliminate preferential growth. Reflectivities of 75-95% in the 0Β’-20c range are currently obtained from the Ni/C-Ti system. The Ti Be multilayer system
The reflectivity of multilayer mirrors depend on the interface roughness created during deposition of the layers. In order to smoothen the interfaces, we have investigated the influence of argon ion bombardment on the interface roughness of a Ni/Ti multilayer deposited by ion beam sputtering. The de
