Granular superconductors are known to operate as fast, sensitive, low-          noise radiation detectors in the infrared, submillimeter and visible            regions, probably through Josephson-like coupling among the                     superconducting grains.  The new family of high temperature (Tc>90K)            copper oxide superconductors including Y1Ba2Cu307 and Gd1Ba2Cu307               evince granular behavior and may show similar or enhanced detector              performance, with the enormous added advantage of operation at and              above 77K.  This proposal outlines an approach to materials and                 devices to rapidly evaluate the feasibility of this application,                especially in the middle infrared spectral region.  It represents               exploration of new technology emerging from a major breakthrough in             materials science, and a step toward ensuring American competitiveness          in this area.
