Abstract
Calculation of Silicon Plasmas with a Relativistic Collisional Radiative Average Atom Code
Highlights
The collisional radiative code ATMED CR [1,2,3,4,5] developed in the Average Atom formalism has been conceived to compute the population distribution of relativistic atomic levels, the average ionization as well as the main atomic and radiative properties of steady-state and temporal plasmas of pure chemical elements or mixtures
The atomic model inside ATMED CR is based on a New Relativistic Screened Hydrogenic Model (NRSHM) with a set of universal screening constants including nlj-splitting that has been obtained by fitting to a large database of 61,350 atomic high-quality data entries, compiled from the National Institute of Standards and Technology (NIST) database of U.S Department of Commerce and from the Flexible Atomic Code (FAC) [6,7]
Silicon steady state and temporal plasmas are modeled with ATMED CR, proposed in the scientific literature or in the 10th Non-LTE Code Comparison Workshop [21] of interest for high energy density facilities
Summary
The collisional radiative code ATMED CR [1,2,3,4,5] developed in the Average Atom formalism has been conceived to compute the population distribution of relativistic atomic levels (nlj-splitting), the average ionization as well as the main atomic and radiative properties of steady-state and temporal plasmas of pure chemical elements or mixtures. 3 there are modeled with ATMED CR silicon steady state and temporal plasmas, some of them proposed in the 10th Non-LTE Code Comparison Workshop [21], of interest for several fields of research in high energy density physics as Z-Pinch machines or astrophysics, inertial τ ( ω) = σ ( ω)ρ L / 2. It is used the photon confinement probability applied to radiative rates defined as: PC ( ω)= 1− P( ω). TN rad eV : Radiation temperature of Planckian Radiation Field number N
