      abstract     = {An improved moveable in vacuo XUV fluorescence detection
                      system was employed for the laser cooling of bunched
                      relativistic (𝛽 = 0.47) carbon ions at the Experimental
                      Storage Ring (ESR) of GSI Helmholtzzentrum Darmstadt,
                      Germany. Strongly Doppler boosted XUV fluorescence (∼90
                      nm) was emitted from the ions in a forward light cone after
                      laser excitation of the 2s–2p transition (∼155 nm) by a
                      new tunable pulsed UV laser system (257 nm). It was shown
                      that the detected fluorescence strongly depends on the
                      position of the detector around the bunched ion beam and on
                      the delay (∼ns) between the ion bunches and the laser
                      pulses. In addition, the fluorescence information could be
                      directly combined with the revolution frequencies of the
                      ions (and their longitudinal momentum spread), which were
                      recorded using the Schottky resonator at the ESR. These
                      fluorescence detection features are required for future
                      laser cooling experiments at highly relativistic energies
                      (up to 𝛾∼ 13) and high intensities (up to 1E11
