  2. GANIL physics cases • 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  Ensuring these physics cases with the appropriate ancillaries detectors The mechanical integration has to take into account this broad list of configurations

  3. Angles >10 deg for fission & MNT AGATA 1p at GANIL : Ancillary devices At 0° as separator (vaccum/gas-filled) In G1 coupled to VAMOS (+ EXOGAM2): SIBs, RIBs • Charged particle array for transfer reaction MUST2/TIARA : (d,p) etc … program with SIB and RIB • Charged particle array for prompt tagging : DIAMANT • Neutron detector (Nwall) • Charged particle array for Recoil Decay Tagging : MUSETT • Scintillator : BaF2 array, LaBr3 • Future detector : NEDA (n) , GASPARD ( ?), PARIS (LaBr3) Cryogenic target ? We ensure the coupling to AGATA through the VME AGAVA card
