Abstract

The effects of proton irradiation on the performance of films and microwave devices made from the high temperature superconductors YBa₂Cu₃O_7-δ and Tl₂Ca ₂BaCu₂O₈ have been measured and can be explained in terms of radiation-induced changes in material parameters such as surface impedance, critical current and transition temperature. Changes in material parameters can in turn be linked to atomic displacement effects
