✦ Synopsis

consideration of the thermal propagation of a half infinitive normal zone in a superconductor with time-dependent current is given. The model implies tamperatureindependent coefficients of the thermal conductivity equation and the change in the dissiptative conductor properties at a certain critical temperature T s. The main regularities of the process and qualitative differences from the process of direct current zone propagation have been elucidated. The normal zone oscillations at high frequencies are shown to be mainly influenced by the process of thermal conductivity along the conductor. At low frequencies the zone propagation may be described by quasistationary formulae. Expressions for temperature profiles and normal zone velocity propagation have been obtained by a method of successive approximations.
