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: An overview of atomic physics experiments at the heavy ion Test Storage Ring (TSR) is given in this article, where the enhancement of the beam intensity by stacking, the beam lifetime, and electron cooling of these ion beams are discussed.

TL;DR: In this article, laser cooling and partially Doppler-suppressed spectroscopy on stored ions at 5.4% speed of light in the test storage ring (TSR) heavy ion storage ring was discussed.

TL;DR: In this paper, the authors presented a clear understanding of laser-ion interactions under storage ring conditions to prepare the basis of laser cooling of fast-stored ion beams in addition to precise data for beam properties such as absolute velocity, momentum spread, and lifetime.
