CERN Accelerating science

The MINIBALL spectrometer utilizes successfully the huge variety of post-accelerated radioactive ion beams provided by REX-ISOLDE at CERN. In-beam γ-ray spectroscopy after Coulomb excitation or transfer reactions is performed with optimized setups of ancillary detectors for particle detection. An overview of the technical details of the full MINIBALL setup, including beam monitoring devices and methods to deal with beam contamination, will be presented. The physics program is covering a wide range of shell model investigations from the light sd-shell nuclei up to the Pb region. Especially the enlarged availability of exotic heavy ion beams enables unique studies of collective properties up to the actinide region. In future the HIE-ISOLDE project will provide a promising perspective for new MINIBALL experiments.
