Superconducting Coils for AC Currents Using YBCO Coated Conductors

This report results from a contract tasking Institute of Electrical Engineering as follows: The Grantee will investigate experimental studies of superconducting coils wound with the second generation of superconductors (11 G), which have YBCO superconducting layer deposited on a metallic substrate The behavior of coils carrying AC (alternating) currents with frequencies of the order of 100 Hz will be studied Short sample experiments and those with test coils using AC tolerant (filamentary) conductor under development and experiments with saddle type winding will also be performed.
