The international FAIR project is promising the highest intensities for relativistic beams of stable and unstable heavy nuclei, combined with the strongest available electromagnetic fields, for a broad range of experiments. This will allow the extension of atomic-physics research across virtually the full range of atomic matter, i.e. concerning the accessible ionic charge states as well as beam energies. In SPARC experiments in two major research areas are planed: collision dynamics in strong electro-magnetic fields and fundamental interactions between electrons and heavy nuclei up to bare uranium. In the first area we will use the relativistic heavy ions for a wide range of collision studies. In the extremely short, relativistically enhanced field pulses, the critical field limit (Schwinger limit) for lepton-pair production can be surpassed by orders of magnitudes and breakdowns of perturbative approximations for pair production are expected. The other class of experiments will focus on structure studies of selected highly-charged ion species, a field that is still largely unexplored; with determinations of properties of stable and unstable nuclei by atomic physics techniques on the one hand, and precision tests of quantum electrodynamics (QED) and fundamental interactions.

APAPES - Atomic Physics with Accelerators: Projectile Electron Spectroscopy 

The APAPES initiative establishes in Greece the discipline of Atomic Physics with Accelerators, a field with important contributions to fusion, hot plasmas, astrophysics, accelerator technology and basic atomic physics of ion-atom collision dynamics, structure and technology. This is being accomplished by combining the existing interdisciplinary atomic collisions expertise from three Greek universities, the strong support of distinguished foreign researchers and the high technical ion-beam know-how of the Demokritos Tandem accelerator group into a cohesive initiative. The new experimental setup includes a single stage hemispherical spectrometer with injection lens and 2-dimensional PSD combined with a doubly-differentially pumped gas target. It has been used in previous work at Kansas State Univ., but moved to the Athens Tandem since 2010. This high efficiency, high-resolution ZAPS system is ideally suited for use in the electron spectroscopy of weak ion beams.
