N2 - We investigated the possibilities and problems of beam strippers in the different heavy ion accelerator components of a possible rare isotope accelerator (RIA) facility. We focused on two beam stripping positions in the RIA heavy ion driver where benchmark currents of up to 5 particle μA 238U were projected at energies of 10.5 MeV/u and 85 MeV/u, respectively. In order to select feasible stripper materials, data from experiments with uranium beams at the Texas A&M cyclotron and the Gesellschaft fuer Schwerionenforschung (GSI) accelerator were evaluated. Based on these results thermal estimates for a possible design were calculated and cooling simulations with commercially available software performed. Additionally, we performed simulations with the GEANT4 code on evaluating the radiation environment for our beam stripping solution at the 85 MeV/u position in the RIA driver.
