Performance gap of Nb3Sn cavities
Nb3Sn is a superconductor that could work at higher temperature and reach twice the field of niobium. Real Nb3Sn cavities reach well under half of that predicted field, for reasons not fully known.
Why it matters
Nb3Sn cavities would allow compact accelerators cooled by simple cryocoolers and higher gradients for large linacs.
