Production of cold, strongly localized highly charged ions (HCIs) has been an experimental challenge for two decades. We succeeded in re-trapping and sympathetically cooling HCIs [1] - produced with an electron beam ion trap - in our cryogenic radiofrequency linear Paul trap. The strongly suppressed thermal motion (mK scale) of the co-crystallized HCIs will be a great advantage for high precision laser spectroscopy of forbidden transitions in HCI. Those are particularly interesting both for fundamental research, such as searching for physics beyond the Standard Model, and for technological applications such as high accuracy atomic optical clocks. Our first test experiment will be the study of the 2P3/2-2P1/2 M1 transition in Ar13+ at 441nm.
