SPIRAL2 at GANIL: Next Generation of ISOL facility for intense secondary radioactive ion beams — •Sydney Gales — GANIL (DSM-CEA/IN2P3-CNRS) Blvd. Henri Becquerel, F-14076 Caen cedex, France

During the last two decades, secondary Radioactive Ion Beams (RIB) has allowed the investigation of a new territory of nuclei with extreme N/Z called *terra incognita*. The quest for Rare Isotope Beams (RIB), which are orders of magnitude more intense than those currently available, is the main motivation behind the design and construction of the next generation of RIB facilities. As selected by the ESFRI committee, the next generation of ISOL facility in Europe is represented by the SPIRAL2 project to be built at GANIL (Caen, France). SPIRAL 2 is based on a high power, CW, superconducting LINAC,delivering 5 mA of deuteron beams at 40MeV (200KW) directed on a C converter+ Uranium target and producing more 1013 fissions/s. The expected radioactive beams intensities in the mass range from A=60 to A=140, will surpass by two order of magnitude any existing facilities in the world. These unstable atoms will be available at energies between few KeV/n to 15 MeV/n. The same driver will accelerate high intensity (100*A to 1 mA), heavier ions up to Ar at 14 MeV/n. Under the 7FP program of European Union called*Preparatory phase* , the SPIRAL2 project has been granted a budget of about 4M€ to build up an international consortium around this new venture. The status of the construction of SPIRAL2 accelerator and associated physics instruments in collaboration with EU and International partners will be presented.
