  • Publication number: 20240306285
    Abstract: A system and method for treating a cavity comprises preparing a superconducting radio frequency (SRF) cavity for removal of a dielectric layer from on an inner surface of the SRF cavity, subjecting the SRF cavity to a heat treatment in order to remove the dielectric layer from the inner surface of the SRF cavity, and preventing the development of a new dielectric layer on the inner surface of the SRF cavity by preventing an interaction between the inner surface of the SRF cavity and atmospheric gasses.
    Type: Application

  • Publication number: 20220151055
    Abstract: A system and method for treating a cavity comprises arranging a niobium structure in a coating chamber, the coating chamber being arranged inside a furnace, coating the niobium structure with tin thereby forming an Nb3Sn layer on the niobium structure, and doping the Nb3Sn layer with nitrogen, thereby forming a nitrogen doped Nb3Sn layer on the niobium structure.
