Program to Study AC Loss in High-Tc Superconductors

摘要

Work performed under this program consisted of (a) consultative work with Wright-Patterson Air Force Base, (b) joint work with WPAFB to develop a concept for converting YBCO films deposited on a wide substrate strip into a conductor with a pattern of narrow spiral filamentary strips for AC operation, (c) calculation of the additional losses due to substrates on YBCO conductors and sheaths on BSCCO type conductors, and (d) new loss theory for polycrystalline high-T(c) superconductors based on Maxwell's equations.
