Stylus ion trap for enhanced access and sensing



Robert Maiwald, Gerd Leuchs, Dietrich Leibfried, Joseph W. Britton, James C. Bergquist, David J. Wineland


We experimentally characterized a novel radio-frequency (rf) ion trap geometry formed by two concentric cylinders over a ground plane. These traps allow for optical and physical access over more than 2 pi solid angle reaching 91% and 96% of 4 respectively in two of the three traps tested. We discuss fabrication of the traps, their characterization using single laser cooled 24Mg+ ions and some potential applications of similar trap structures in quantum optics, sensing and microscopy.
