✦ Synopsis


Magnetic instabilities or flux jumps in multifilamentary superconducting composite conductors, exposed to a time-varying magnetic field perpendicular to the superconducting filaments, are studied. In particular, expressions for the stability limit field are determined for cases when the magnetic diffusivity is greater than the thermal diffusivity and vice versa. Examples are presented for NbTi composite conductors with CuNi matrix and Cu matrix.

Investigations of transient field losses in multifilamentary composite conductors carrying dc transport currents, I, are presented. As shown previously, the total loss is best characterized by a normalized transport current i = I/Ic and a dimensionless field-change rate = rBe/Bp, where r is the rela

At relatively high ampfitudes and variation rates of a transverse external field, the saturated zone may occupy a considerable part or the entire space of the composite. Differential equations have been derived which enable one to calculate the time dependence of the magnetic moment of screening cur
