By integrating a niobium superconducting radio-frequency resonator with a linear Paul trap, the CryPTEx-SC experiment demonstrates a new ion trap concept developed for achieving ultra-low noise conditions [1]. Filtering of the trap drive by the high quality factor of the resonator and suppression of magnetic field fluctuations by the Meissner–Ochsenfeld effect will be beneficial for precision spectroscopy of highly charged ions using quantum logic techniques. Highly charged ions are captured and sympathetically cooled by Be+ ions in the superconducting ion trap. This enables the exploration of dynamics in mixed species Coulomb crystals consisting of ions with disparate charge-to-mass ratios.
