Scanning Submillimeter Laser Reflectometer for Precision Surface Resistance Measurements

2Superconductors, materials that carry electrical current without any resistance, can make electronic circuits more efficient and communications between remote locations easier. In the past two years, the materials developments of superconductors have progressed so much that the quality of the materials can no longer be measured even with the most sophisticated techniques. Xsirius Superconductivity, Inc is developing a new measurement technique using lasers to scan the surface of the superconductors to measure the quality. This new measurement technique improves detection sensitivity by 100 times. This technique will be useful for developing superconducting materials for use in computer chips, communication systems, and particle accelerators.
