Automated loading of Highly Charged Ions in a Paul Trap — •Lukas Fabian Storz, Vera M. Schäfer, Elwin A. Dijck, Stepan Kokh, José R. Crespo López-Urrutia, and Thomas Pfeifer — Max-Planck-Institut für Kernphysik, Heidelberg

Automatizations for experiments are crucial to maximize productivity and accuracy. We have implemented an algorithm using the fluorescence of Be-Ions detected on a CCD camera to automatically load large Be-Crystals. The presence of an HCI causes a void of Be⁺ in the crystal, which shows as a hole in the image. Its radius depends on the HCI charge state, and HCI recombination with residual gas changes it, allowing us to monitor the density at the trap over several months. Simultaneously the secular frequencies also yield the charge state. Our algorithm is applicable to similar ion trapping experiments and serve for their optimization.
