Abstract

Traditionally, shock experiments primarily yield shock and particle velocity data from which pressure, specific volume, and internal energy are inferred using conservation relations. Direct measurement of the properties of shock-loaded materials is difficult due to the extreme conditions and single-shot nature of shock experiments as well as the fast time response required (<1 μs). We describe several novel fluorescent probe techniques possessing nanosecond response that we have developed to measure the pressure, temperature, and viscosity of shocked materials.
