Theoretical and Experimental Study of Noise in Superconductors.

Abstract

Measurements of Noise in superconductors were made in a variety of geometries. Thin films, coupled thin films, foils, Josephson junctions and magnets were studied. The only intrinsic source discovered, of any consequence, was flux flow noise. Extrinsic noise with a wide variety of frequencies and sources was a problem because of the extraordinary sensitivity of superconducting devices. Theoretical concentration was on flux flow noise because of its practical importance. However some general features of intrinsic and extrinsic noise were elucidated. (Author)
