"New Superconducting Materials for the Next Generation Particle Accelerators"

Dr. Alex Gurevich
Florida State University


Achieving accelerating field gradients above 50 Mv/m in superconducting cavities for particle accelerators will require novel cavity designs and materials other than Nb given that the SRF performance of the best Nb cavities has approached the limits set by the physics of the superconducting Meissner state under strong rf fields. In this talk I will give an overview of the fundamental physics and materials science issues which determine these SRF limits, and discuss possible ways of increasing the cavity performance well beyond the intrinsic limits of Nb technology. One possibility based on the multilayer coating of Nb cavities is already being pursued by several groups worldwide. This approach opens up the opportunity of increasing the accelerating field gradients and reducing the operating costs by taking advantage of many existing materials with superconducting characteristics much better than those of Nb.
