A new atomic beam source was designed and developed at the MPIK which uses optical pumping combined with a spatially-dependent magnetic field to produce a cold atomic beam for use in ion-atom collision studies at the TSR at MPIK. A ``push'' laser is used to transfer the pre-cooled atoms from this two-dimensional MOT to a three-dimensional one which is combined with a reaction microscope (MOT-REMI) capable of performing kinematically complete experiments with an energy resolution about ten times greater than that of a conventional reaction microscope. A 2D-MOT was chosen over other atomic target sources (e.g Zeeman slower) for its collimated beam which provides a higher density of atoms and for its compact design.
