Super Transition Arrays: A Tool for Studying Spectral Properties of Hot Plasmas

چکیده
For the theoretical study of X and extreme-UV spectra ions in plasmas, quantum mechanics brings more detailed results than statistical physics. However, it is impossible to handle individually billions levels that must be taken into account order properly describe hot plasmas. Such can gathered electronic configurations or superconfigurations (groups configurations) corresponding calculations rely on appropriate methods, for local non-local thermodynamic equilibrium In this article we present basic principles Super-Transition-Array approach as well its practical implementation. During last decades, performed with SCO code (Superconfiguration Code Opacity) have been compared opacity measurements. The includes static screening by plasma suited studying density effects (for example pressure ionization) equation state. recently developed SCO-RCG Opacity combined Robert Cowan’s “G” subroutine) combines methods from fine-structure (detailed-level-accounting) using subroutine RCG code. enables us obtain very significantly improve interpretation experimental spectra. formalism still cornerstone several codes, new ideas are emerging, such Configurationally Resolved-Super-Transition-Array extension Partially Resolved-Transition-Array concept superconfiguration method.

Spectral Properties of Electromagnetic Turbulence in Plasmas
We report on the nonlinear turbulent processes associated with electromagnetic waves in plasmas. We focus on low-frequency (in comparison with the electron gyrofrequency) nonlinearly interacting electron whistlers and nonlinearly interacting Hall-magnetohydrodynamic (H-MHD) fluctuations in a magnetized plasma. Nonlinear whistler mode turbulence study in a magnetized plasma involves incompressib...
متن کاملA Unified Approach for Studying the Properties of Transition Systems
In this paper a systematic method for generating, comparing and proving the properties of transition systems is presented. It is assumed that any property of a system can be defined by giving a set of ‘target’ states and a type of reachability. Ten differcqt types of reachability are proposed; by appropriately choosing the set of target states, a family of ten potentially different properties i...

EVALUATION OF THE MECHANICAL PROPERTIES OF NIOBIUM MODIFIED CAST AISI H 13 HOT WORK TOOL STEEL
Abstract: mechanical properties of AISIH 13 hot-work tool steel have been studied. Cast samples made of the modified new steel were homogenized and austenitized at different conditions, followed by tempering at the specified temperature ranges. Hardness, red hardness, three point bending test and Charpy impact test were carried out to evaluate the mechanical properties together with characteriz...
