We have loaded our first Beryllium ions into a cryogenic Penning trap. The ions were loaded using laser ablation from a solid Beryllium target, combined with two-photon ionization. The picture shows a cloud of  ions, imaged by shining a laser beam onto the cloud and sending the resonance...

We have demonstrated ground state cooling of 9Be+ ions using microwave fields produced by a custom microwave "antenna" embedded into a surface-electrode ion trap. The viewgraph shows the suppression of the red (cooling) sideband which occurs close to the motional ground state, while the blue...

Frederik Jacobs has joined the Hannover ion trappers as a bachelor student. For his bachelor thesis he will work on the simulation of magnetic fields originating from an ion trap setup with permanent magnets. The setup will enable for the realization of longlived qubit states in the surface paul...
