Effect of Neutron Irradiation on Tc of Pb-Doped BiSrCaCuO Superconductor

Abstract
A Pb doped BiSrCaCuO superconductor was irradiated in a TRIGA MARK III reactor up to a neutron fluence of 7.6×1017 n/cm2. The measured superconducting transition temperature (T c) after irradiation was decreased to 92.5 K from nonirradiated data of 102 K. The fractional decrease of the T c was compared with results fon other superconducting materials. Some recovery of irradiation-induced T c decrease was observed.
