Current Research Interests
In the Plasma Laboratory we study processes in plasmas subjected to high-energy
deposition. We examine the interaction of nonequilibrium plasmas with strong
electric and magnetic fields, the propagation of ionization fronts, the
production of shock waves, conversion of energy in pulsed-power systems,
generation of fast particle beams, generation of magnetic shocks, development
of collective fluctuating fields, and plasma-surface interactions. Implications
on the development of plasma switches, intense x-ray sources, generation
of electron and ion beams, and industrial applications based on plasma-surface
interactions are studied. The use of hot and dense plasmas for x-ray
lasers and the use of the intense x-ray sources for high-resolution microscopy
of living biological cells are considered.
The diagnostic methods are based on fast, high-resolution plasma
spectroscopy of spontaneous emission in the visible, U.V., vacuum UV, and
x-ray regions, as well as on spectroscopy of laser absorption and laser-stimulated
emission. Theoretical analysis of the experimental data is based on detailed
modeling of atomic-physics processes that govern the atomic/ionic spectral-line
broadening, atomic-level splitting under electric and magnetic fields,
field ionization, multiple ionizations and time-dependent collisional-radiative
calculations.
Magnetohydrodynamic simulations are used to account for the nonequilibrium
kinetic and transport processes in the plasmas.The research in the laboratory
is relevant to applications of various plasma systems and analysis of astrophysical
data.
