Since 2001, SPIRAL at GANIL has been delivering radioactive ion beams of gaseous elements of unique intensity and purity for physics experiments. Recently, a project was formed to upgrade SPIRAL for making use of so far unexploited capabilities for radioactive ion beam production. Neutron deficient beams from condensable elements should soon become available with unequalled intensities for a...

ISOLDE is known for the production of very exotic radioactive ion beams far from stability. During the past online period a number of isotopes could be added to that list and are now available for experiments. Systematic investigations of isotope yields and other release properties promote the understanding of the complex processes of isotope production and extraction and help evaluating...

Calcium oxide powder targets have been successfully used at ISOLDE-CERN to produced neutron deficient exotic argon isotopes and carbon isotopes, released as CO and CO2 molecules. Such targets outperform other related targets used to produce the same beams, such as MgO sintered powder or TiOx fibers. However, either some CaO target units displayed slow release rates (or low absolute yields)...

At ISOLDE RILIS isotopes are resonantly ionized by high pulse repetition rate wavelength-tunable lasers. In recent years the performance of RILIS was substantially improved due to upgrade stages of the laser setup. The dye laser installation has been completely renewed including the replacement of copper vapor pump lasers by solid state Nd:YAG lasers. As part of the RILIS upgrade program, a...
34. The Laser Ion Source and Trap (LIST): Improving the Selectivity of the Resonance Ionization Laser Ion Source

Highest ionization efficiency combined with effective isotope selectivity is of utmost importance for most on-line experiments on exotic, short-lived radionuclides, in particular for those with the lowest production rates. At ISOLDE, the ionization technique that most closely meets these requirements is the Resonance Ionization Laser Ion Source (RILIS), where the atoms of a chosen element are...
45. Highlights of the Radiation Protection Group Activities in 2011 in Support of ISOLDE Operation and Projects

Several processes and activities carried out in the ISOLDE facility for the production and use of Radioactive Ion Beams present radiological risks. For this reason, the Radiation Protection (RP) Group is involved in the daily operation of the facility to ensure that appropriate mitigation measures are implemented and that the relevant Radiation Protection rules and best practices are followed....
