✦ Synopsis

The heat transfer characteristics on the HTSC-surface in a pool of liquid nitrogen under conditions of slow increasing or decreasing transport current have been experimentally studied. It was observed that there are instabilities of heat transfer regimes regarding the small thermal disturbances (fluctuations). These unstable heat transfer regimes are accompanied by large temperature overshoots and, therefore, must be taken into consideration in designing HTSC-elements of superconducting systems.
