The "Radioactive EXperiment at ISOLDE" (REX-ISOLDE) was proposed at the end of 1994 to perform a pilot experiment to study neutron-rich isotopes around N=20 and 28 using Coulomb excitation and transfer reactions. A novel concept to accelerate the existing low-energy, singly-charged ISOLDE beams and a new high-efficiency gamma-ray array, called Miniball, dedicated to low-multiplicity...

52. The REX-ISOLDE post accelerator – from first stumbling beams to sophisticated ion juggler

Invited

REX-ISOLDE has now been operational as post-accelerator of radioactive ion produced at ISOLDE for over ten years. Close to 100 isotopes from 30 different elements have been accelerated and delivered to numerous experiments at varying beam energies. The technical challenges encountered during the installation and commissioning phase of the machine will be briefly reviewed, and the present...

31. MINIBALL at REX-ISOLDE: pioneering position-senstive Ge detectors

Invited

With the approval of the REX project at ISOLDE in 1995 an intensive discussion on the design and construction of a dedicated γ-ray array started. Due to the low intensity of the radioactive beams high detection efficiency was needed. On the other hand, as the γ-rays are emitted from nuclei moving with 5-10% of the speed of light a high granularity of the array was mandatory in order to limit...
