Physics and Challenges of Superconducting Cavities for Particle Accelerators and Theoretical Implication towards Higher Performance:

Invitation to the world of superconducting cavities

Abstract

We discuss the physics of superconducting resonant cavities for particle accelerators, including the basics of a superconducting cavity, Meissner state stability, and surface resistance together with related scientific and technological challenges. Ongoing research and some proposals for solving the challenges are also discussed.
