Title:  Next Generation Superconducting RF Accelerators

Host:  Jim Sethna

Abstract:  Accelerators are powerful tools for science and engines for industry. Superconducting RF (SRF) is the gold-standard for acceleration of charged particles, but future, continuous-mode accelerators will require very efficient SRF accelerating structures with extremely high quality factors Q0 to maintain feasible cryogenic cooling loads. Recent results on impurity-doped niobium and on triniobium-tin (Nb3Sn) coated SRF cavities indicate that these novel surfaces can lead to next-generation SRF cavities. In this talk I will give a broad overview of recent advances in fundamental superconducting RF R&D, and will discuss how these will advance the frontier of accelerator driven sciences.
