The Dual-Axis Radiographic Hydrodynamic Test Facility (DARHT) is a facility being built at Los Alamos National Laboratory as part of the Department of Energy's stockpile stewardship program. It uses two large x-ray machines to record three-dimensional interior images of materials simulating nuclear explosion testing (including subcritical testing).
