Atomic clocks based on highly charged ions are prosperous candidates for quantum sensors with unprecedented precision, sensitive for physics beyond the Standard Model [1,2]. To drive the clock transitions, an extreme-ultraviolet frequency comb was constructed based on cavity-enhanced high-harmonic generation of the driving 100 MHz near-infrared frequency comb [3]. Harmonics up to 42 eV are generated in a gas jet and are subsequently guided through a beamline towards a superconducting Paul trap for direct XUV-comb spectroscopy [4, 5].
