Cooling of trapped charged particles to the mK range or even below is crucial in many precision experiments, but can be a challenge when suitable laser transitions are missing. We recently demonstrated a new sympathetic cooling method to cool a single proton via image currents of a laser-cooled Be+ cloud located in a separate trap. This concept is promising, because it is not limited to small distances and is generally scalable. In particular, any kind of charged particles can be cooled, including antimatter and highly charged ions.
This talk summarizes our previous work and reports about our recent progress towards an advanced coupling scheme based on a detuned LC-circuit.
