Post Shock Temperature Measurements in Metals and Rocks

Abstract: Post-shock temperature is an important quantity in shock physics experiments for constraining the dynamic equations-of-state of materials. A high-speed infrared multiwavelength pyrometer has been developed at the Los Alamos National Laboratory for operating in the temperature range from 400 to 1200 K. With customized front end optics, permitting concurrent VISAR experiments in the same optical path, it is being used at the new gas gun in the Department of Earth and Planetary Sciences at Harvard University. This paper describes the experimental setup and results obtained to date on molybdenum, aluminum and basalt.
