UWFDM-1047 Diagnosing Plasma Conditions in Targets Irradiated by Intense Light Ion Beams Using K-alpha Satellite Line Intensity Ratios
The characteristics of Kα satellite line emission generated in intense light ion beam experiments are investigated. Inner-shell x-ray lines are emitted from moderatetemperature (T ∼ 10 − 10 eV) plasmas as 2p electrons of the target ions fill in K-shell vacancies created by beam ion-impact ionization. We focus in particular on the utilization of line intensity ratios from He-like and Li-like ion...
متن کاملUWFDM-878 Thermal Ionization Effects on Inner-Shell Line Emission for Au Targets Heated by Intense Light Ion Beams
In order to deduce the experimental beam conditions from the observed x-ray line emission spectrum of high Z elements, atomic radiative data for transition energies and oscillator strengths, ion-atom impact ionization cross sections, Coster-Kronig yields, and fluorescence yield are needed. In this paper, we report on calculations to study the dependence of these atomic data on ionization stage....
متن کاملAtomic and optical properties of warm dense copper.
The emission of x rays from warm dense matter is of great interest for both spectroscopic diagnostics and development of intense x-ray sources. We report the results from the collisional-radiative steady-state (CRSS) modeling of atomic and optical properties of copper plasmas at near-solid and solid-state density for a range of temperatures. The CRSS model is validated against the available dat...
متن کاملNLTE Radiative Transfer and Model Atmospheres of Hot Stars
Stellar atmospheres are open systems and thus cannot be in thermodynamic equilibrium (TE). The “Local Thermodynamic Equilibrium” (LTE) is a working hypothesis which assumes TE not for the atmosphere as a whole but for small volume elements. As a consequence, the atomic population numbers are depending only on the local (electron) temperature and electron density via the SahaBoltzmann equations....
متن کاملAssessment of secondary particles in breast proton therapy by Monte Carlo simulation code using MCNPX
Background: The present study aimed to investigate the equivalent dose in vital organs, including heart and lung, due to secondary particles produced during breast proton therapy. Materials and Methods: The numerical ORNL female-phantom was improved and simulated using the Monte Carlo MCNPX code. The depth-dose profile of proton beams with different energies was simulated. The proper energy ran...
