      abstract     = {Gas-filled stopping cells are used at accelerator
                      laboratories for the thermalization of high-energy
                      radioactive ion beams. Common challenges of many stopping
                      cells are a high molecular background of extracted ions and
                      limitations of extraction efficiency due to space-charge
                      effects. At the FRS Ion Catcher at GSI, a new technique for
                      removal of ionized molecules prior to their extraction out
                      of the stopping cell has been developed. This technique
                      utilizes the RF carpet for the separation of atomic ions
                      from molecular contaminant ions through their difference in
                      ion mobility. Results from the successful implementation and
                      test during an experiment with a 600 MeV/u 124 Xe primary
                      beam are presented. Suppression of molecular contaminants by
                      three orders of magnitude has been demonstrated. Essentially
