Highly charged ions (HCI) with narrow optical transitions are promising systems for tests of fundamental physics and improved optical frequency standards. However, to fully make use of these systems the high charge state production needs to be combined with the techniques of single ion trapping at cryogenic temperatures.
We present a cryogenic ion trap setup for highest precision quantum logic spectroscopy of HCI. The HCI are extracted from a room temperature permanent magnetic EBIT and re-trapped in a Paul trap together with Be+ ions [1]. These ions provide sympathetic cooling and act as the logic species in the quantum logic scheme. Initial data from our low vibration cryogenic system and Paul trap will be presented.
As the next step we will perform optical spectroscopy on the well investigated fine structure transition of Ar13+ and determine the isotope shift between 36Ar13+ and 40Ar13+.
