  • Patent number: 5028786
    Abstract: A cryogenic detector comprises an array formed from a plurality of spherical grains made of type I superconducting material arranged in a preselected pattern and each having a preselected size (generally less than about 100 microns in diameter). Also disclosed is a method of making such an array by depositing a film of selected thickness of type I superconducting material on a substrate, etching the film to provide an array formed by a plurality of discrete pixels, melting the pixels under conditions whereby the pixels are transformed into substantially spherical shape, and cooling to freeze the molten pixels into substantially spherical grains.
