S3: The Super Separator Spectrometer for SPIRAL2 stable beams

S3(Super Separator Spectrometer) is a device designed for experiments with the very high intensity stable beams of LINAG, the superconducting linear accelerator of GANIL, which will be built in the framework of SPIRAL2. These beams, which will provide ions with A/Q = 3 in SPIRAL2 phase one, can reach intensities up to 1mA for light ions, A<50. These unprecedented intensities open new opportunities in several physics domains, e.g. super-heavy and very-heavy nuclei, spectroscopy at and beyond the drip line, isomers and ground state properties, multi-nucleon transfer and deep-inelastic reactions. An international collaboration has been formed to propose physics experiments and develop technical solutions for this new instrument.
