Abstract

An integral equation approach to solving for the flux front profile in the Bean critical-state model, for a constant Jc, is described for a superconducting tape. This analysis takes into account the demagnetizing effects of the tape surfaces and is applicable to cylindrically symmetric external fields. The particular case of an external coil above one surface with its central axis perpendicular to the superconducting tape is considered for fields sufficient to cause penetration of magnetic flux through the tape. © 1996 The American Physical Society.
