MICROWAVE MEASUREMENTS OF THE SURFACE IMPEDANCE OF SUPERCONDUCTING TIN AND LEAD.

Abstract

In this dissertation, the results of two different experiments are reported. In the first experiment, temperature dependent measurements were made of the surface impedance of superconducting tin and lead at 2.85 and 11.2 GHz; these surface impedance measurements were compared with the Mattis and Bardeen theoretical result, including a finite electron-pair coherence length and a finite electron mean free path. In the second experiment, temperature dependent measurements were made of the ac critical magnetic field of superconducting tin at 2.85 GHz; these ac critical magnetic field measurements were compared with dc critical magnetic field measurements. These two experiments stemmed from the program at Stanford University to develop a superconducting linear accelerator. (Author)
