“…Yet, this method relies on Coulomb scattering in the same way as IBS and thus its efficiency is inherently reduced for dilute beams and especially for the anticipated crystalline beams [27,28]. However, also with refined laser cooling techniques, coupling the longitudinal and the transverse motion via the storage ring dispersion [30,31], only an ambiguous observation could be made at the TSR [32]. The evidence of a sudden transition of the beam into a state without IBS at a linear density which corresponds to the formation of a one-dimensional linear string was strikingly reminiscent to what had been expected for the crystallization of the beam.…”

The phase transition of an ion beam into its crystalline state has long been expected to dramatically influence beam dynamics beyond the limitations of standard accelerator physics. Yet, although considerable improvement in beam cooling techniques has been made, strong heating mechanisms inherent to existing high-energy storage rings have prohibited the formation of the crystalline state in these machines up to now. Only recently, laser cooling of low-energy beams in the table-top rf quadrupole storage ring PAaul Laser cooLing Acceleration System (PALLAS) has lead to the experimental realization of crystalline beams. In this article, the quest for crystalline beams as well as their unique properties as experienced in PALLAS will be reviewed.

“…The final tuning has to be done carefully as crossing the center of the bucket leads to an equally strong driving of the synchrotron motion, visible in the lower half of Figure 2. The second scheme, invented at TSR [14,15], relies on the repeated interaction of the ions circulating in the bucket with the laser tuned to optimum cooling close to the center of the bucket. Both schemes have been systematically studied at the ESR and detailed results will be published elsewhere.…”

We report on the first laser cooling of a bunched beam of multiply charged C 3þ ions performed at the ESR (GSI) at a beam energy of E ¼ 1:47 GeV. Moderate bunching provided a force counteracting the decelerating laser force of one counterpropagating laser beam. This versatile type of laser cooling lead to longitudinally space-charge dominated beams with an unprecedented momentum spread of Áp=p % 10 À7 . Concerning the beam energy and charge state of the ion, the experiment depicts an important intermediate step from the established field of laser cooling of ion beams at low energies toward the unique laser cooling scheme proposed for relativistic beams of highly charged heavy ions at SIS 300 (FAIR).
