摘　　要：Ion deceleration has played a critical role in ion-related research when the ions are produced in the form of a high-energy beam.We present a deceleration method combining electrostatic lens and ion trap technique,which can effectively decelerate ions to energy below the trapping potential of a typical ion trap.The experiments were performed on metastable 1s2s3S1Li+ions,and demonstrated that the kinetic energy could easily be reduced from^450 e V to a few e V,with the latter being confirmed using the Doppler-shifted fluorescence spectra.
