PRODUCTION OF AND STUDIES WITH SECONDARY RADIOACTIVE ION-BEAMS AT LISE

The doubly achromatic spectrometer LISE, installed at GANIL, has delivered secondary radioactive beams for the past 6 years. Essentially, it consists of two dipole magnets selecting (in A/Z) and refocussing (achromatically) the projectile-like fragment beams emitted at 0-degrees. Important features of LISE and selected experimental results will be discussed. LISE was substantially upgraded, recently, by adding a Wien filter, providing secondary radioactive beams of still increased intensity and isotopic purity.
