The Ultra-low energy Storage Ring

The QUASAR group combines developments in accelerator sciences with measurements on quantum systems, with a particular focus on antimatter research. The group is leading the development towards the ultra-low energy storage ring at FLAIR. This includes in-detail studies of the beam dynamics of electrostatic storage rings, design of a combined fast/slow extraction system, development of beyond state-of-the-art beam instrumentation, and investigations into atomic physics experiments to be realized with the USR.

HE Accelerator

The group also carries out research in high energy accelerators, including beam loss detection, investigations into , propagation and monitoring beam halo formation, and the exploitation of synchrotron radiation for beam profile measurements.

Medical Accelerators

The use of particle accelerators for medical applications has become increasingly important with dedicated facilities being built up around the world. In close collaboration with HIT, the group has contributed to the design of a novel magnet-current based beam extraction system for medical synchrotrons. It is furthermore carrying out extensive studies on the biological effects of antiprotons on cells which is closely related to the above-mentioned USR studies.

SC Linacs

Finally, the group is contributing to an international effort in optimizing superconducting cavities for future high current accelerators. Among others, we are studying the effects of higher order modes on the particle beam and carry out studies on different superconducting materials through sample studies in a quarter wavelength resonator at CERN.

The group’s international structure and close collaboration with partners from around the world thus provides a fruitful ground for beyond state-of-the-art developments in a number of different fields.
