Recent Fermilab discoveries of nitrogen doping and effective magnetic flux expulsion allow quality factors in bulk niobium SRF cavities several times higher than the previous state-of-the-art from only two years ago. The combined approach using both of these techniques allows to minimize both residual and BCS surface resistances leading to the world-record quality factors of >2e11...

Recent advances at Cornell University in the development of Nb3Sn cavities have demonstrated the huge potential of this alternative material for very high efficient SRF acceleration. Nb3Sn has a critical temperature of 18 K, approximately twice that of niobium, allowing Nb3Sn cavities to have exceptionally high intrinsic quality factor Q0—which indicates extremely small cryogenic...
