CX-270197: Integration of Microwave Readout into Nuclear Process Monitoring – University of Colorado, Boulder

The University of Colorado, in collaboration with Los Alamos National Laboratory and Savannah River National Laboratory, proposes to demonstrate that high-resolution γ-ray spectroscopy, based on emerging microcalorimeter sensors, can determine elemental and isotopic fractions with accuracy comparable to much slower mass spectrometry and with far better accuracy than germanium γ-ray sensors. An instrument called SLEDGEHAMMER will be used in a series of measurement campaigns beginning with actinide reference materials and progressing to measurements of actual process materials from a working reprocessing facility.
