Abstract :
In the present paper, a modified form of the critical state model is suggested to describe the anisotropic J/sub c/ effect of BSCCO high T/sub c/ superconducting tapes. By this model, the intrinsic stability of a tape conductor is analyzed. The criterion suggests that the width and the thickness of the tape should be limited in combination. For a given tape thickness, a critical width (corresponding to a given angle) under which the tape becomes intrinsically stable is proposed, This criterion suggests a 2D limitation for high T/sub c/ superconducting tape, Additionally, the model suggests that flux-jump field is a function of the field orientation.
