Use of deep penetration flash radiography in conventional ordnance, and impact dynamics research and development
The use of penetrating flash radiography (FXR) as a diagnostic tool in explosive ordnance and impact dynamics research and development is discussed by the presentation of numerous examples of its utility in analyzing dynamic interactions and in bench marking hydrodynamic computer codes. The Los Alamos Terminal Ballistic Test Range is described. Examples of the use of the new Los Alamos Pulsed Intense X raY (PIXY) machine for deep-penetration radiography are also presented. PIXY is a state-of-the-art, flash x-ray machine recently installed at the Los Alamos National Laboratory (LANL). Along with the LANL sled track and the large- and small-bore gun range, it is a major component of the LANL Terminal Ballistic Test Range. When operating at full voltage, the machine is capable of obtaining a radiographic image through 8-12 in. of armor steel or ceramic. Deep-penetration flash radiographs show the capabilities of PIXY and further illustrate the enhanced information now available to the conventional munitions research and development community. Commercially available radiographic machines are also described and examples of their use presented. It is concluded that flash radiography is an excellent diagnostic tool for benchmarking hydrodynamic and finite-element computer codes.
