Low-Temperature Neutron Irradiation Effects in Superconducting Technetium and Niobium
The effect of irradiation on magnetic properties of superconductors has been the subject of recent investigations.1–3 Our primary purpose in observing the change in magnetic behavior is to determine the nature of the mechanism by which magnetic fluxoids are pinned in superconductors. Information on the distribution, size, and strength of pinning centers introduced by fast neutron irradiation at helium temperatures is the goal of a continuing investigation on technetium, niobium, and niobium alloys.
