AB - Charge stripping of intense heavy ion beams is a major challenge in current and future linear heavy ion accelerators. Conventional stripping techniques are limited in their applicability, e.g. solid carbon foils suffer from short lifetimes at high intensities. One possible alternative is the use of a plasma as a stripping medium, which the presented work focuses on. The main goal of the studies is the prediction of the final charge state distribution of the ion beam. Rate equations were implemented numerically, taking into account different models for ionization, recombination and energy loss processes. First quantitative results are presented in form of an overview of the charge state distributions of different charge stripping media. For fixed projectile properties and target phase, it is observed that the mean charge state q₀ decreases for increasing nuclear charge Z_{\}text{T} of the target. Plasmas show significantly increased q₀ for the same Z_{T}. The width d of the charge state distributions is larger for higher Z_{\}text{T}. The latter is caused by multiple loss of the projectile and decreases the maximum stripping efficiency by typically less than a factor of 2.
