or 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. TRSAXS at the newly-commissioned Dynamic Compression Industry of the Advanced Photon Source at Argonne National Laboratory, researchers detonated small samples of TATB-based (triamino trinitrobenzene) PBX 9502 while high-brilliance x-rays are scattered by the solid carbon products formed in the detonation.
