美國洛斯阿拉莫斯國家實(shí)驗(yàn)室光譜測量方向博士后招聘

　　What You Will Do

　　You will be working with LANL’s Shock and Detonation Physics Group as a highly productive experimental postdoctoral researcher to 1) design and field novel spectroscopic diagnostics for elucidating the chemical kinetics in burning high explosives (HE), 2) perform ultrafast spectroscopic measurements on HE excited by laser driven shock waves, and 3) connect measurement results to chemical kinetic model predictions to determine consistency with existing reaction pathway hypotheses. Combustion experiments will measure time resolved emission, absorption, and Raman spectroscopies of gas phase product species concentrations and temperatures as a function of time. Ultrafast spectroscopic measurements will measure picosecond visible and mid-infrared transient absorption spectroscopies on HE undergoing strong shock excitation produced by ultrafast laser direct drive or nanosecond laser driven flyer plates. Kinetic modeling will utilize existing software platforms such as Cantera. The unifying goal is the pursuit of knowledge regarding how HE chemically react under combustion and shock conditions, enabling more predictive reactive burn models important to performance and safety calculations.
