Multi-Ion Plasma Shock Formation From Colliding Supersonic Jets on the PLX
POSTER
Abstract
The LANL Plasma Liner Experiment (PLX) facility has began a study of multi-ion shock fronts in a connected vacuum chamber. Using the state-of-the-art, multi-ion, Vlasov-Fokker-Planck (VFP) code, iFP,1 we explore shock-driven multi-ion stratification effects in the collision of two PLX-like plasma jets. We compare these simulation results to PLX diagnostic data: including spatially-resolved spectroscopy of the shock structure, and ion temperature profiles via Doppler broadening. Finally, supplemental fluid and multi-physics modeling was done to assess the role of missing physics (e.g., ionization and multi-dimensional effects; which are absent from iFP).
