Developments at ISOL Facilities: from ISOLDE towards EURISOL

In-flight separation and Isotope Separation On -Line (ISOL) are the two main methods for producing radioactive ion beams. A brief description of the ISOLDE facility at CERN, which has accumulated 50 years of experience of the ISOL technique is given. The HIE -ISOLDE project, which is a major upgrade of the energy and intensity of ISOLDE is described. The long term plans for ISOL in Europe culminate with the EURISOL facility which has been developed within a pan-European design study. The EURISOL concept resulting from this study is presented
