      abstract     = {We report on the sympathetic cooling and Coulomb
                      crystallization of xenon highly charged ions (HCIs) with
                      laser-cooled Ca$^+$ ions. The HCIs are produced in a compact
                      electron beam ion trap, then charge selected, decelerated,
                      and finally injected into a cryogenic linear Paul trap.
                      There, they are captured into $^{40}$Ca$^+$ Coulomb
                      crystals, and co-crystallized within them, causing dark
                      voids in their fluorescence images. Fine control over the
                      number of trapped ions and HCIs allows us to realize
                      mixed-species crystals with arbitrary ordering patterns. By
                      investigating Xe$^{q+}$--Ca$^+$ strings, we confirm the HCI
                      charge states, measure their lifetime and characterize the
                      mixed-species motional modes. Our system effectively
                      combines the established quantum control toolbox for Ca$^+$
                      with the rich set of atomic properties of Xe highly charged
                      ions, providing a resourceful platform for optical frequency
                      metrology, searches for signatures of new physics, and
                      quantum information science.},
