The Cygnus Dual Beam Radiographic Facility, located nearly 1,000 feet underground in the U1a underground laboratory at the Nevada National Security Site, is used to illuminate subcritical special nuclear material in dynamic experiments to capture two high-resolution flash radiographs, contributing to research on pulse power, X-ray source characterization, diode physics and radiography.
