Chemistry of Metal Plasma in Controlled Chemical and Extreme Conditions
Abstract
We propose a comprehensive research program to investigate thermochemical processes of metal plasma in the post-nuclear detonation period. Using a pulse-laser and an electric arc generator, we will generate a plasma plume of nuclear simulant metals (Cu, Co, Sr, Bi, and depleted U) in controlled chemical (O2, N2, air, H2O, SiO2, and CaCO3) and pressure-temperature conditions and investigate three fundamental postnuclear events: (A) the formation of metal plasma, using time-resolved emission spectroscopy and high-speed microphotography; (B) the chemistry of hot dense metal particles, using time-resolved synchrotron x-ray diffraction; and (C) the chemical and elemental specification of reaction fallouts, using synchrotron x-ray fluorescence and electron microscopic methods. This research program will develop advanced analytic technologies for nuclear forensic sciences and provide real-time data critical to describing plasma chemistry following nuclear detonation. It will also provide graduate and postdoctoral students with hands-on experiences in state-of-the-art advanced forensic technologies and offer them the excitement of fundamental defense research
