Abstract
The surface resistance of a superconducting niobium cavity oscillating in the TE11n modes has been measured over a frequency range from 1.7 to 7.8 GHz, and a frequency dependence proportional to f2 ± 0.1 has been found. The result differs from the f1.7 dependence predicted by the approximate microscopic theory. A possible explanation for the observed anomaly is given by smearing of the density‐of‐states maximum due to inhomogeneities in the superconductor.This publication has 14 references indexed in Scilit:
