Abstract : Flux-flow noise in Type 2 superconductors is investigated experimentally. The observed noise turns out to be shot noise as expected from the assumption that the flux-flow voltage is generated by independently drifting flux bundles. Bundle sizes as large as 100 to 100,000 are found in vanadium foils dependent on the bias condition. The experiment shows qualitative agreement with the theory. (Author)
