Abstract [en]

We have trapped and stored Ar16+ ions in a cylindrical Penning trap and managed to evaporatively cool the ion clouds axial motion to thermal temperature. The stored ion cloud is excited axially by fast switching of the trap potentials whereafter the cloud starts to oscillate coherently. The cooling is observed from the time of flight resolved peaks originating from the oscillations while lowering the trap potential slowly. The peaks widths decrease with increased storage time.
