Studies of RF-superconductivity properties of niobium film-coated cavities at CERN

Extensive tests have been performed on several cavities, operated at 1.5 GHz in the TMoio mode, obtained by sputter-coating niobium on copper, in order to study the physical phenomena responsible for

RF system: superconductivity
niobium: surface
