The goal of this project was to build a commercially viable metallic microcalorimeter (MMC) g-spectrometer with an ultra-high energy resolution <50 eV for accurate non-destructive assay (NDA) of nuclear materials. Improved NDA simplifies and accelerates safeguards analyses in the nuclear fuel cycle and enhances capabilities to detect the diversion of nuclear materials for illicit purposes. High-resolution MMC g-spectrometers can also improve the accuracy of nuclear data that NDA is based on.
