At the Max-Planck-Institute for Nuclear Physics in Heidelberg, a new project named TrapRemi has been launched. It attempts to combine a Zajfman - ion trap with a Reaction-Microscope (Remi) to investigate the quantum dynamics of molecular ions. This thesis first describes the end phase of the Zajfman trap assembly: Reaching ultra-high vacuum in themain chamber, the proper wiring of all components and the optical alignment of the ion trap electrodes. Then, first results from ion source characterizations and ion injection in the Zajfman trap are presented.Ultimately, itwas possible to oscillate an ion packet up to six times inside the trap. Thus it was shown that the apparatus is able to successfully and reproducibly store ions. For the future, further optimizations must be made to reach storage times up to several hundreds of miliseconds, corresponding to thousands oscillations. Subsequent steps would be the implementation of Remi components such as Helmholtz coils and position sensitive detectors.
