Systems, methods and apparatus for radial amplitude assisted transfer (RAAT) in mass spectrometers are provided in which ions for RAAT are accelerated along a longitudinal axis of a mass spectrometer in order to decrease the magnitude of excitation energy of radially excited ions in an ion trap that allows the radially excited ions to exit the ion trap. Hence, the radially excited ions exit the ion trap with reduced radial energy thereby decreasing the exit angle of the radially exited ions from the ion trap. Furthermore, combined forces on the ions are such that radially excited ions exit the ion trap while unexcited ions remain in the ion trap.
