Title: $$Nb_3Sn$$ Superconducting RF Cavities: R&D Progress at Fermilab and Opportunities

Abstract

$$Nb_3Sn$$ becomes superconducting at twice as high temperature as our standard SRF material niobium. This allows us to efficiently operate $$Nb_3Sn$$ cavities at 4.4 K instead of the usual 2 K. This reduces cryogenic costs and even makes it possible to use a cryocooler instead of a large, complex cryogenic plant. The superheating field Hsh of $$Nb_3Sn$$ is twice that of niobium. Hsh is thought to be the ultimate limit for a defect-free superconductor. $$Nb_3Sn$$ cavities being made today are still about a factor of 4 away from this ultimate limit, but R&D has been leading to substantial progress towards this goal.
