Automated imaging optimization of an ion microscope for ultracold Rydberg experiments — •Phatthamon Kongkhambut, Thomas Schmid, Christian Veit, Nicolas Zuber, Robert Löw, and Tilman Pfau — 5. Physikalisches Institut and Center for Integrated Quantum Science and Technology IQST, Universität Stuttgart

The experimental study of ion-atom scattering in the ultracold regime has so far remained elusive. We propose a novel method using Rydberg molecules to reach the quantum regime of ion-atom collisions [1] and present our new experimental setup which allows for the spatially resolved detection of the scattering process. The scattering process is initialized by the photoionization of a Rydberg molecule, providing well defined starting conditions for the collision. The scattered ions are imaged by an ion microscope and a delay line detector. Using automated feedback and optimization algorithms, we plan to tune the operation parameters of the ion microscope and minimize the aberrations. A magnification of more than 1000x can be realized with a field of view of 34 micrometers and depth of view of 25 micrometers. The expected resolution is below one micrometer.
