In this new volume of a series presenting international results in theory and practice of high temperature superconductors (HTS), Narlikar (Inter-University Consortium for DAE Facilities, India) presents five contributions devoted to the issues of irradiation induced defects and cationic disorders and their influences on superconducting properties. Specific topics include displacement damage effects, angular dependent vortex dynamics in superconductors with columnar defects, swift heavy ion irradiation induced enhancement in flux pinning, irradiation induced oxygen knock-out, and modeling defect structure of HTS by neutron irradiation.
