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
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)
In G1 coupled to VAMOS (+ EXOGAM2): SIBs, RIBs
AGATA 1p at GANIL : Ancillary devices
At 0° as separator (vaccum/gas-filled)
Angles >10 deg for fission & MNT
Cryogenic target ? We ensure the coupling to AGATA through the VME AGAVA card

What is not good :• Charged particle detectors : DSSD, CUPS, DANTE etc … are difficult to insert• Except if we modify the conic part of the chamber for not so close pack configuration
L’angle de 14° est une contrainte qui laisse un cône sans matière pour les détecteurs EXOGAM à 90°
