Superconducting NBTI Microwave Cavity

Abstract
We have investigated the properties of a rectangular cavity made of ``hard'' superconducting Nb0.52Ti0.48 alloy and resonating in the TE‐101 mode at 9.125 GHz. Preliminary results in fields up to 10 kG show that such a device could be very useful in applications where high Q's in the presence of strong magnetic fields are desirable.
