An ion microscope to study Rydberg physics and ultracold ions — •Nicolas Zuber, Christian Veit, Phatthamon Kongkhambut, Florian Meinert, Robert Löw, and Tilman Pfau — 5. Physikalisches Institut and Center for Integrated Quantum Science and Technology IQST, Universität Stuttgart, Germany

In addition to spectroscopic tools developed to study Rydberg atoms, spatially resolved detection enables the possibility to directly observe spatial correlations or transport phenomena. Information can be extracted on a single particle level, as it is done in quantum gas microscopes for ground state atoms or with several detection techniques for Rydberg atoms. Along the same lines we integrated an ion microscope, consisting of three electrostatic lenses combined with a spatially resolving delay line detector, to observe Rydberg atoms and ions in our ultracold rubidium gas. The ion microscope provides a high resolution below one micrometer and a tunable magnification between 200 and 1500 with single particle sensitivity. The field of view for the largest magnification 25 micrometer only limited by the detector size. Additionally the setup features an electric field control, which permits a well controlled suppression of electric stray fields. On the poster we present details of our experimental setup and first measurement results of the ion microscope.
