Experiments at New X-Ray Facility May Lead to Better Explosive Modeling

For the first time in the U.S., time-resolved small-angle x-ray scattering (TRSAXS) is used to observe ultra-fast carbon clustering and graphite and nanodiamond production in the insensitive explosive Plastic Bonded Explosive (PBX) 9502, potentially leading to better computer models of explosive performance. “Carbon clusters are produced during the chemical process of detonation in high explosives,”

New Dynamic Compressor Sector to Study Materials at Extreme Conditions

A new, first-of-its-kind-worldwide research capability will help unravel the mysteries of material behavior at extreme conditions and short time scales in support of the National Nuclear Security Administration’s (NNSA’s) vital national security missions. NNSA, the Department of Energy’s (DOE’s) Argonne National Laboratory and Washington State University (WSU) will dedicate the new Dynamic Compression Sector (DCS)
