Development of a Multi-Frame Detection System to Obtain Real-Time X-Ray Measurements in Shocked Energetic Materials
Abstract
This DURIP award was used to acquire/assemble a Multi-frame Detection System to obtain real-time x-ray diffraction and phase contrast imaging measurements (micrometer resolution) in energetic materials (EMs) subjected to well-characterized shock wave loading. Such measurements will permit for the first time the ability to routinely examine changes in crystal structure (phase transformations), microstructure, and crystal-binder interfaces in real-time (while they are happening in nanoseconds to microseconds) in dynamically compressed EMs. The importance/relevance of such measurements for fundamental research, and for the safe and optimal use of EMs, cannot be emphasized enough. X-ray diffraction and phase contrast imaging measurements will not only provide new mechanistic insights into EM response, but will also serve to evaluate multiscale modeling results. The multi-frame detection system is deployed at the Dynamic Compression Sector (DCS) located at the Advanced Photon Source (Argonne), a first-of-its-kind user facility dedicated to dynamic compression science. Having this multi-frame detector capability (for x-ray diffraction and imaging) available for dynamic experiments on EMs provides a novel and unique experimental capability for the Office of Naval Research and other Department of Defense research related to EMs. X-ray diffraction and imaging measurements on dynamically compressed EMs have not been possible before. In addition, a new generation of research scientists will be educated on using such facilities for EM related research.
