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
EXOGAM coupled to VAMOS: • Spectroscopy of n-rich nuclei Beam: 238U @ 5.5 MeV/u, (i ~ 2pnA) Target : 9Be, 12C,48Ca,70Zn, 198Pt … (1 mg/cm2) • Full identification of the heavy recoil in VAMOS • Shell evolution toward 54Ca (M. Rejmund et al) • lifetime measurement with a plunger in n-rich nuclei beyond 68Ni (J Ljungvall et al; A Dijon et al, I. Celikovic et al) • Delayed and prompt gamma spectroscopy around 68Ni (A Dijon et al) • Transfer induced fission reactions (F. Farget et al, M. Rejmund et al. A. Görgen et al.) • Spectroscopy of heavy element Os (J. Valient-Dobon et al)

We ensure the coupling to AGATA through the VME AGAVA card
Design done by STFC Daresbury in close collaboration with GANIL • An important work of integration is on-going • Final design review 1st week of December • Projection T1 -2013 • 9 months of construction estimated • On-going discussion with the IPHC workshop for the construction of the support • Workshop for the extendedplateform not yetdefined
Nominal configuration Which configuration for which physics ? GANIL is designing a new target chamber, target holder and beam pipe to ensure most of the experiments (DIC,fission, fusion) Compact configuration
