Ultra-high quality factors in superconducting niobium cavities in ambient magnetic fields up to 190 mG

A. Romanenko, A. Grassellino, A. C. Crawford +2

Ambient magnetic field, if trapped in the penetration depth, leads to the residual resistance and therefore sets the limit for the achievable quality factors in superconducting nio…

Dependence of the residual surface resistance of superconducting RF cavities on the cooling dynamics around $T_{c}$

A. Romanenko, A. Grassellino, O. Melnychuk +1

We report a strong effect of the cooling dynamics through $T_{c}$ on the amount of trapped external magnetic flux in superconducting niobium cavities. The effect is similar…
