Instrumentation for ultrafast optical measurements of shocked reactive materials
Abstract
The Defense University Research Instrumentation Program (DURIP) is designed to improve the capabilities of U.S. Universities to conduct research and to educate scientists and engineers in selected technical areas of importance to national defense. DURIP funding provides for the acquisition of research equipment and instrumentation for this purpose. This proposal is for the purchase of equipment to develop a high-speed optical shock wave diagnostic. The P.I., Professor Dana Dlott, of the University of Illinois, Urbana-Champaign will use the equipment to augment and enhance research capabilities in the area of energetic material characterization. The objectives of this project are to study the shock initiation of tiny quantities (micrograms or nanograms) of energetic materials while they are subjected to powerful shock waves. The creation and evolution of hot spots in the energetic will be studied using a high-speed camera acquired with this contract. Pulses from a femtosecond laser will be used to measure the real-time reflectivity of the energetic materials in order to improve our ability to measure temperatures by stand-off optical methods, and these pulses will be generated using a pump laser and laser frequency converter acquired with this contract. This project will advance knowledge by revealing the fundamental mechanisms of impact initiation of energetic materials and by acquiring data that can be used to verify the predictions of advanced computer simulation models.
