Abstract

The results of theoretical investigation of thermally fine composite superconductor stability to local thermal disturbances in variation of the external magnetic field, cooling agent temperature, improvement of superconductor critical properties are presented. It is shown that there exist regions of the magnetic field, in which the allowed energy of disturbance vary negligibly both in decreasing the helium bath temperature from 4.2K to 1.8K and in transition to superconductors with an increased critical density of the current. The analysis of the thermal stability variation in transition to high temperature superconductors shows that the increase of critical energies is of the same order as that of the capacity variation.
