Description

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 performance of REX-ISOLDE will be compared with the initial specifications and predictions given in the proposal from 1994. Subsequent to the installation the machine has undergone continuous development in order to respond to different experimental requirements concerning, for example, beam energy and purity; ion mass range and lifetime; and beam intensities and timing structure. The different methods addressing these issues will be discussed. Finally, a glimpse of the performance that can be expected from the machine in the future will be given.
