In the PRIOC experiment three innovative experimental techniques are combined in order to study ion-atom collisions with unprecedented detail: A magneto-optical trap (MOT) for target preparation is implemented in a Reaction Microscope that enables momentum detection of all collision partners. This 'MOTRemi' setup is operated in an ion storage ring where intense and brilliant ion beams can be provided. Lithium is used as target which is particularly interesting for its simplicity with only one weakly bound outer shell electron. In test experiments on photoionization the performance of the MOTRemi has been tested and an excellent resolution for recoil ion as well as electron momenta has been achieved. Results of first experimental runs on single ionization in ion-atom collisions will be presented.
