The Bi-based high-temperature superconductors are micaceous: grains cleave preferentially in the ab plane when fractured, so that powders consist of thin platelets. Superconducting current transport… (More)

We obtain general predictions for the distribution of wave function intensities in position space on the periodic orbits of chaotic ballistic systems. The expressions depend on effective system size… (More)

A superconducting strong-focusing cyclotron is being developed for high current applications. Alternating-gradient focusing is provided by ~ 6 T/m superconducting beam transport channels which lie in… (More)
