Abstract

The future international accelerator Facility for Antiproton and Ion Research (FAIR) encompasses 4 scientific pillars containing at this time 14 approved technical proposals worked out by more than 2000 scientists from all over the world. They offer a wide range of new and challenging opportunities for atomic physics research in the realm of highly-charged heavy ions and exotic nuclei. As one of the backbones of the Atomic, Plasma Physics and Applications (APPA) pillar, the Stored Particle Atomic Physics Research Collaboration (SPARC) has organized tasks and activities in various working groups for which we will present a concise survey on their current status.

31. Design Considerations for Converting Laser-Accelerated Electron Beams into Brilliant X-Ray, γ-Ray and Neutron-Beams.

Abstract

High-power short-pulse lasers focussed into a gasjet can produce intense brilliant high-energy electron beams. The transport and acceleration of the intense electron beams requires the development of many new concepts in accelerator physics. Focusing these electron beams through an undulator one can realize an X-Free-Electron-Laser (FEL) or a γ-FEL, producing brilliant high-energy photon beams. With these intense monochromatic γ beams high-brilliance, low-energy polarized micro-neutron beams can be generated via resonant (γ,n) reactions. The monochromatic γ beams also open up new fields in nuclear physics. The compact, comparatively cheap laser systems and FEL’s allow us to produce brilliant particle beams, which offer interesting facilities “at home” with many applications. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]

32. Crystalline ion beams in the RF quadrupole storage ring PALLAS.

Subjects
ION bombardment, CRYSTALLIZATION
Abstract

We report on the crystallization of laser cooled Mg[sup +] ion beams circulating in the table-top rf quadrupole storage ring PALLAS at a velocity of 2800 m/s (beam energy 1 eV). A sudden collapse of the transverse beam size and the low velocity spread clearly indicate the phase transition to a one-dimensional linear string of ions. This crystalline beam shows exceptional stability, surviving for more than 3000 revolutions without cooling. Close to the phase transition, the spatial beam profile of non-crystalline beams was found to exhibit an unexpected two component Gaussian distribution. Although its origin is not yet fully understood, we can exploit this effect for the identification of two- and three-dimensional crystalline beams. [ABSTRACT FROM AUTHOR]

33. Laser-cooling of ions and ion acceleration in the RF-Quadrupole ring trap PALLAS.

Abstract

We report on the commissioning of the table-top RF-Quadrupole storage ring PALLAS*, dedicated to the experimental realization of crystalline ion beams. Images of large prolate [sup 24]Mg[sup +]-ion crystals are presented, operating PALLAS locally as a linear rf-trap and applying laser-cooling, beautifully confirming prior theoretical and experimental work. For few-ion strings, a radial oscillation of the crystal was observed, stabilized only by additional indirectly cooled impurity ions. On the challenging way towards crystalline ion beams, we demonstrate the acceleration of an ion distribution initially at rest, i.e., the very first operation of PALLAS as a storage ring, still to be heavily improved. Further applications, as the systematic investigation of residual gas damping, or sympathetic cooling for, e.g., the mass determination of heavy radioactive isotopes are briefly discussed.
