Gamma-ray spectroscopy of very neutron-rich nuclei populated in Deep Inelastic collisions or induced fission using VAMOS to identify the reaction products in Q, A and Z. Spectroscopy of heavy elements towards SHE and N=Z nuclei populated by fusion – evaporation with VAMOS in gas-filled mode. Spectroscopy of p-rich nuclei at the N=Z line using the N-wall Spectroscopy using existing and new SPIRAL1 beams GANIL physics cases Ensuring these physics cases with the appropriate ancillaries detectors The mechanical integration has to take into account this broad list of configurations
