A Compact Tunable Narrow-Bandwidth and High-Photon-Flux Turnkey XUV Source for Experiments with Highly Charged Ions at Storage Rings

The development of table-top extreme ultraviolet (XUV) light sources has paved the way to a vast variety of applications. Achievable XUV-photon fluxes of lab scale high-harmonic XUV setups can reach up to those typically present at synchrotron sources and free-electron lasers (FELs) [1]. Thus, a variety of experiments comes into reach that was formerly tied to these large scale facilities. The combination of the table-top type XUV sources combined with heavy ion storage rings enables manifold fundamental studies and experiments on core level transitions, highly excited states, or transitions in highly-charged ions [2].
