Jérôme Daligault(505) 667-3547daligaul@lanl.gov, Travis Sjostrom(505) 665-0054sjostrom@lanl.gov. We have made a particular emphasis in the analysis of the validity of the assumption of local thermodynamic equilibrium and the influence of the atomic description in the calculation of the radiative properties.

The objective of our research is to achieve a theoretical understanding of the microscopic properties of dense, strongly coupled plasmas and of their consequences on the macroscopic properties such as transport. Microscopic, mechanical and thermal properties of spark plasma sintered ZrB 2 based composite containing polycarbosilane derived SiC Author links open overlay panel S. Chakraborty a D.

Background information on dense plasma physics as well as details of our current research may be found throughout this site. All Rights Reserved. Das a D. Ghosh c In particular, we have addressed the effect of plasma self-absorption in the radiative precursor, the influence of the radiation emitted from the shocked shell and the plasma self-emission in the radiative precursor, the cooling time in the cooling layer, and the possibility of thermal instabilities in the postshock region. Plasma activation of polymers is highly essential to enhance the surface properties of the polymers. All Rights Reserved. Microscopic properties of xenon plasmas for density and temperature regimes of laboratory astrophysics experiments on radiative shocks. "Plasma is a charged gas, with strong Coulomb [or electrostatic] interactions," Hu told Live Science. Influence of atomic kinetics in the simulation of plasma microscopic properties and thermal instabilities for radiative bow shock experiments. In the first one, a study of radiative properties (such as monochromatic and the Rosseland and Planck mean opacities, monochromatic emissivities, and radiative power loss) and of the average ionization and charge state distribution of xenon plasmas in a range of plasma conditions of interest in laboratory astrophysics and extreme ultraviolet lithography is performed.

The mechanism of ionization of molecules or atoms by collisions due to thermal motion or by radiation processes and interaction with neutral atoms is of little interest in laser-produced plasmas, which have plasma temperatures exceeding 100,000° centigrade (corresponding to 10 eV). 2002 Apr;65(4 Pt 2B):046418. doi: 10.1103/PhysRevE.65.046418. USA.gov. In nearly all of the following cases Z is one, because we shall consider hydrogen ions with a mass M = 1.67 x 10−24 grams, or of two or three times this value if deuterium or tritium ions are used.
