Multilayer coating for higher accelerating fields in superconducting radio-frequency cavities: a review of theoretical aspects

Abstract

Theory of the superconductor-insulator-superconductor (S-I-S) multilayer structure in superconducting accelerating cavity application is reviewed. The theoretical field limit, optimum layer thicknesses and material combination, and surface resistance are discussed. Those for the S-S bilayer structure are also reviewed.
