A recoil mass separator was constructed for experiments of nuclear astrophysics using radioactive nuclear beams, and its performance was tested. The observed beam suppression factor around M ∼ 20 was 10-4 when the system was tuned for ΔM = 1 heavier ions than beam ions. With a charge state breeding technique, it became 10-8 when the system was tuned for Δq = +1 larger ions than beam ions.
