Improvements of the beam line optics at the Heidelberg electron beam ion trap (EBIT) have led to an enhancement of the ion extraction efficiency. To take advantage of this development, different types of experiments in the low energy regime are planned. In order to study the interaction of highly charged ions with surfaces or gas targets at low kinetic energies, it is of importance to provide a slow monoenergetic and well focused ion beam with small angular divergence. Therefore, a multi-purpose ion beam deceleration station has been designed which is suitable for both types of work. Its ion optical properties were investigated by means of a numerical simulation, and the design was optimized to meet the mentioned requirements best.
