Technology for Spiral 2

1. Technology for Spiral 2 World leading ISOL facility SPIRAL2 will use a superconducting heavy ion linac together with coupled cyclotrons to produce intense beams of rare isotopes. The beams of exotic nuclei produced and reaccelerated to energies near the Coulomb will provide an excellent complement to the much higher energy beams of other isotopes to be produced by the FAIR facility at GSI. The accelerated nuclei will be extremely neutron rich, often produced as fission fragments, and will be used to study how nuclear shells and nuclear structure evolves to be different for very exotic nuclei. Advanced detector systems such as EXOGAM, TIARA, VAMOS & CHARISSA have been developed by collaborations including major UK effort. Surrey leads the TIARA collaboration and has major roles in the others. The Surrey experimental nuclear physics group is constantly developing new techniques to exploit exotic nuclear beams. Spiral2 is being constructed at GANIL in Caen, France. This will be the world’s largest ISOL facility for the production and acceleration of beams of rare isotopes. www.ganil.fr/spiral2
