Towards Commissioning a Linear Surface Trap for Ions with Real-Time Control and Open-Science Workflows — •Tobias Spanke, Frederike Dörr, Florian Haße, Lucas Eisenhart, Deviprasath Palani, Jörn Denter, Mario Niebuhr, Ulrich Warring, and Tobias Schätz — Physikalisches Institut, Albert-Ludwigs-Universität, Freiburg

We present a modern trapped-ion platform that combines a microfabricated surface-electrode trap, real-time control, and open-science workflows for scalable quantum control and precision collision studies. We report on the commissioning of a linear surface-electrode ion trap from Sandia National Laboratories [1] operated with ARTIQ real-time control and versioned experiment pipelines for experiments with ²⁵Mg⁺ ions. A stabilized multi-wavelength laser system enables robust loading, Doppler cooling, and coherent control [2]. As a first application, we implement "Phoenix Flyby Calibration", a laser-triggered neutral-gas source for time-resolved benchmarking of ion-neutral collision dynamics in our trapped-ion apparatus. This commissioning lays the groundwork for systematic studies of background-gas-induced heating and loss in surface traps and for transferable protocols for real-time control and open-science workflows in trapped-ion experiments.
