✦ Synopsis

A theory of thermal stabilization of composite superconductors, making it possible to choose a composite filling coefficient, has been developed. The:influence of the filling coefficinet on full and partial stabilization was investigated in terms of a generalized analysis with the aid of dimensionless variables independent of the filling coefficient Filling coefficient optimal values were found for conditions of full thermal stabilization, at which permissible values of the stability parameter and the transport current density are maximized from the viewpoint of accident-free working capacity of the magnetic system. It was shown that the increase~in filling coefficient of partially stabilized composites can result either in deterioration, or in improvement of the thermal stability of the wire. The existence of the partial stabilization regimes mentioned was:studied under different cooling conditions, current load, and length ef initial~disturbance~section..
