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
particles) of ion beams in the new heavy ion synchrotron
SIS100 at FAIR.},
