Dual-Axis Radiographic Hydrodynamic Test Facility, Research facility in Los Alamos, United States.
The Dual-Axis Radiographic Hydrodynamic Test Facility is a research installation inside Los Alamos National Laboratory in New Mexico that uses two electron accelerators to produce X-rays from perpendicular angles. These X-rays pass through materials during controlled experiments to produce detailed images of what happens inside them under high pressure.
Construction began in 1992 after the United States halted nuclear weapons testing, and the first axis became operational in 1999. The facility was built to give scientists a way to study how materials react under extreme pressure without using real explosives.
The research team at Los Alamos National Laboratory uses this facility to understand how materials behave under extreme pressure without conducting actual explosions. This work is part of programs that maintain knowledge about weapons systems through careful scientific observation rather than testing.
The facility sits inside Los Alamos National Laboratory, a secured government site, so access is limited to authorized staff. A visit by special request may be possible in some cases, but security requirements will apply regardless.
Each X-ray flash produced here lasts only a few nanoseconds, making it possible to capture movement inside materials that would otherwise be invisible. The two accelerators are timed with enough precision to image the same event from two directions at nearly the same instant.
