N2 - Due to the very low thermal conductivity of high temperature superconductors (HTSC), AC losses can result in a non-uniform temperature distribution inside a sample. We report the results of an experimental investigation of the temperature distribution in the wall of the BSCCO hollow cylinder in AC magnetic field. The BSCCO cylinder has a relatively low critical current density of 550 A/cm2 (at 77 K) measured under DC conditions at 1 μV/cm criterion. The temperature of the interior of the cylinder relative to the outside coolant raised 2.5 K at low external magnetic field (approximately 0.04 T). The change in temperature is increased linearly with frequency and as the third power of the applied magnetic field. The experimental results are compared with the theoretical predictions obtained in the framework of the critical state model complemented by the heat equation.
