| Abstract Scope |
Carbon clustering behind the detonation front is believed to delay chemical equilibrium at late times in insensitive, carbon-rich explosives. Accurate modeling of both the unreacted and product equations of state is important to predicting the performance of high explosives and an improved description of solid detonation carbon is necessary. Time-resolved small-angle x-ray scattering (TR-SAXS) can provide a in situ measurements of the evolution of solid/fluid detonation products in real time behind the detonation front, including particle size, shape/morphology, and electron density. Here, we will describe the experimental apparatus implemented at the Dynamic Compression Sector at the Advanced Photon Source, and results on several types of explosives including PBX 9502 (TATB/Kel-F 800), PBX 9501 (HMX/Estane), and Composition-B (TNT/RDX). The results will be discussed in the context of reactive flow and hydrodynamic simulation. An analysis of errors will be discussed including how improvements could be made to measuring detonation carbon evolution using x-ray light sources. |
