The 1s-2s two photon transition of singly ionized hydrogen-like helium at 60 nm is an interesting candidate for precision tests of bound state QED. Rapid progress in the development of high-power XUV frequency combs lets high resolution spectroscopy of this transition come in sight for the first time. We report on important steps towards this goal. In our novel 6-rod RF trap, we generated and analyzed cold mixed crystals.
