TL;DR: A 7 Li + -ion beam was overlapped with resonant copropagating and counter- propagating laser beams and a strongly enhanced narrow peak appeared in the Schottky noise spectrum in addition to the uncooled ion distribution.

TL;DR: The Heidelberg heavy ion test storage ring TSR started operation in May 1988 and the first experiments were performed in 1989 as mentioned in this paper, where the lifetime of the ion beams observed in the first experiment can be explained by interactions with the residual gas.

TL;DR: In the authors' experiments, this process presently limits the ratio between the density-dependent Coulomb energy and the longitudinal thermal energy spread to a value on the order of 1, where liquid rather than gaseous behavior of the ion beam is expected to set in.

TL;DR: In this paper, the first time precision spectroscopy on a coasting fast 7Li+ ion beam in a storage ring was performed, where the ion beam moving with 6.4% speed of light was first electron cooled and then merged with two counter-propagating laser beams acting on two different hyperfine transitions sharing a common upper level.

TL;DR: In this paper, the potential of the interaction of laser light with energetic stored ions for spectroscopic purposes as well as for manipulation of the ion velocity is demonstrated, and an outlook to the situation at even higher energies is given.
