Dr. Alexander L. Velikovich, a U.S. Naval Research Laboratory plasma physicist, was recently honored as the 2015 IEEE Plasma Science and Applications Award recipient for advanced plasma theory.
Presented by the Nuclear and Plasma Sciences Society (NPSS), the award recognizes outstanding contributions to the field of plasma science and engineering to include plasma dynamics, thermonuclear fusion, plasma sources, relativistic electron beams, laser plasma interactions, diagnostics and solid-state plasmas.
Author and co-author of more than 170 publications, with over 2,500 citations, Velikovich developed the first analytical theory to calculate the time-dependent growth of compressible Richtmyer-Meshkov (RM) instability in the linear regime, as well as non-linear RM theory explaining reduction of its growth rate for large initial amplitude.
Most recently Velikovich developed a theory explaining the effect of shock-generated turbulence — discovered in numerical simulations at NRL over a decade ago — on the Rankine-Hugoniot jump conditions. Derived from the laws of mass, momentum and energy, many physical effects, first observed on the Nike krypton fluoride (KrF) laser at NRL, were recreated on both the Nova laser at the Lawrence Livermore National Laboratory, California, and the Omega laser at the Laboratory for Laser Energetics (LLE) located in New York.
Velikovich’s research on High Energy Density Physics (HEDP) and Inertial Confinement Fusion (ICF), particularly laser-fusion and Z-pinch-related plasma hydrodynamics, formed the theoretical basis for x-ray generation in Z-pinch plasma radiation. Modeling and interpretation of these results were instrumental in establishing the physical picture of the Rayleigh-Taylor (RT) instability seeding in laser fusion targets caused by the roughness of the front and rear surface of a laser target. Research that later translated into the development of a theory that provided the physical basis for most hydrodynamic experiments performed on the Nike laser over the past decade.
Earning a Master of Science equivalent degree in physics from Moscow State University Department of Physics, Moscow, Russia, in 1974, Velikovich completed a Ph.D. equivalent degree in plasma physics and chemistry awarded by Kapitza Institute for Physical Problems, U.S.S.R. Academy of Sciences in 1978. In 1991 he earned an Advanced Degree of Doctor of Science (equivalent of Habilitation in European Union countries) in Electrophysics awarded by High Current Electronics Institute, Russian Academy of Sciences, Tomsk, Russia. Velikovich started at NRL in 1993 as a contractor, transitioning to federal civil service at NRL in 1999.
