Observation of Cold Collisions Between Trapped Ions and Trapped Atoms

Professor Vladan Vuletic

We produce cold Yb+ ions by photoionization of laser-cooled Yb atoms, and load them into a surface-electrode ion trap at rates as large as 10^5 ions/second. The position of the ion trap above the surface can be adjusted via the voltage ratio on the electrodes, allowing us to place the trapped-ion cloud inside the cloud of laser-cooled atoms. We present preliminary measurements of Yb–Yb+ charge-exchange and elastic collisions.
