Charge evolution of swift heavy ions in fusion plasmas

Influence of target temperature, density and atomic number on the charge state of swift heavy ions interacting with hot and dense plasma is considered. Hydrogen targets exhibit strong temperature effects and large non-equilibrium charges, whereas interactions with heavy material are more sensitive to the density effect. Our new average correlated hydrogenic atom model (ACHAM) is presented. It enables us to cover the whole range of target densities of interest for swift heavyion-plasma interaction experiments.
