HIE-ISOLDE – MINIBALL
At the ISOLDE facility at CERN, radioactive ion beams of isotopes all across the chart of nuclides are produced by injecting 1.4 GeV protons on a thick primary target. The produced ions are extracted by an ion source and mass separated using the ISOL method. The selected ions are post-accelerated by REX- and super conducting HIE-accelerators up to an energy of 10 MeV/A and delivered to the experminental station, where they impinge on a thin secondary target. Around this target chamber (see picture to the right) the high-purity germanium (HPGe) detector array MINIBALL (see picture below) and a double-sided silicon strip detector (DSSD) are placed for high energy resolution gamma-ray spectroscopy and particle detection, respectively. A so-called plunger device for the measurement of excited-state lifetimes in the pico-second regime and magnetic moments can replace the target chamber. These experimental setups are used by our group for projectile Coulomb excitation experiments and lifetime measurements using Doppler-shift to study the nuclear structure of rare nuclei.
