Precise control of field ionization ramps enables time resolved detection of different Rydberg states, making the method state selective. In our Experiment the ion detector is tilted and off-centered from the axis of the field electrodes to increase optical accessibility, but in cost of simple ion trajectories.

This talk will present our implementation of electric potentials to ionize the Rydberg states selectively and at the same time guide the ions to the detector. Limitations of the method in terms of suitable states and local Rydberg densities will be discussed.
