Storage and laser cooling of ion beams in the RF-quadrupole ring trap PALLAS — •Tobias Schätz, Ulrich Schramm, and Dietrich Habs — Sektion Physik der LMU-Muenchen, LS Habs, Am Coulombwall 1, 85748 Garching:

PALLAS, a RF-quadrupole ring trap, is additionally equipped with drift tubes for ion acceleration to low energy (eV). This table top RF-quadrupole storage ring should make it possible to investigate the generation and stability of laser cooled 24Mg ion beams with the aim to reach the state of a Coulomb-ordered crystalline structure. We hope to be able to show the transition from established stepwise acceleration of the ions to a uniformly guided and crystaliced ion beam.

On the other hand, PALLAS serves as a prototype for versatile low energy rings, e.g., for the accumulation of Radioactive Ion Beams. Preliminary studies for identification of (trapped) radioactive ions by sympathetically cooling and strongly coupling are investigated.
