The resultant effective pinning of vortices leads to an enhanced persistent current density in the CuO planes, displacement of the irreversibility line to higher temperatures and magnetic fields, and a major reduction in the logarithmic time decay rate of the supercurrent density. Superconducting applications span the range from small scale analog and digital circuits and systems, to large scale applications of electrical power generation, storage, transmission and medical applications such as MRI. The design acceleration gradient for the 1300 MHz RF cavity system is 25 MV per meter. A field mapping theory with a harmonic analysis is applied to interpret both results.
