Analysis of lightning-related risk in outdoor high explosive research.

PDF Version Also Available for Download.

Description

The behavior of materials at high strain rates can be studied using high explosives (HE) as an energy source. Such hydrodynamic experiments may be performed on full-scale systems, requiring kilogram quantities of HE and therefore are performed at outdoor facilities. One such facility is DARHT-the Dual-Axis Radiographic Hydrodynamic Test facility located at Los Alamos National Laboratory in northern New Mexico. DARHT is a very large flash x-ray machine. The high-intensity, short-duration x-ray pulses are beamed through the hydrodynamic experiment to an x-ray camera. Density variations in the materials produce variations in the transmitted beam that are recorded by the camera. ... continued below

One such facility is DARHT-the Dual-Axis Radiographic Hydrodynamic Test facility located at Los Alamos National Laboratory in northern New Mexico. DARHT is a very large flash x-ray machine. The high-intensity, short-duration x-ray pulses are beamed through the hydrodynamic experiment to an x-ray camera. Density variations in the materials produce variations in the transmitted beam that are recorded by the camera. The information in these images is used to understand the basic behavior of materials subjected to very high dynamic pressures and to evaluate the accuracy of computer codes used to model the associated phenomena.
