Non-destructive evaluation apparatus and method for superconducting materials

摘要

An apparatus and method is disclosed for evaluating the superconducting quality of superconducting materials. The materials are wound on a bifilar spool and tested in a cryogenic atmosphere to determine when the material quenches. During the testing procedure, the electromagnetic field, current and temperature imposed on the material are varied and the test results are compared with known results to determine if the material is superconductive. In this way, large samples can be tested in a non-destructive manner.
