  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. 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)

  4. EXOGAM coupled to VAMOS+MUSETT: • Spectroscopy of SHE nuclei • VAMOS + EXOGAM+MUSETT • Vamosat 0 degreeused as separator • Prompt spectroscopyafterRecoildecaytagging (a-decay) in MUSETT Vacuum mode : 22Ne +197Au 214Ac Gas filled mode : 48Ca+198Pt  244Cf Not yet fully funded and operational French grant Agency for Research 2013 request (Saclay -GANIL) genergykeV MUSETT array aenergykeV

  6. Collectivity in N≈Z nuclei: • Enhancementfrom T=0? VAMOS in gas-filled with AGATA and MUSETT (Island of a-emitter) • Onset of collectivity induced by np pairing • near N=Z and closed shells ? • Prompt spectroscopy of light Xe,Te,I isotopes • a and p emitter M. Sandzelius et al., Phys. Rev. Lett. 99, 022501 (2007). Gasfilled mode : 54Fe+54Fe  106Te +2n (25 nb) 54Fe+58Ni  110Xe +2n (50 nb) 54Fe+58Ni  109I +p2n (10 mb)

  8. 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

  9. 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

  10. 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

  11. Total investment cost ~360 k€ Detector lab infrastructure ~15 k€ Optical fibers links ~70k€ ~17k€ Processing room 019 Upgrade ~ 85k€ Cryogenic upgrade, connection ~25 k€ ~150 k€

  12. Collaboration : Local project manager : E.Clément Campaign spokesperson announced : S. Lenzi Call for LOI sent : dead line 25th January 2013 1st workshop 18th to 20st of February organized at GANIL First draft of the working together document sent to AMB ~ 4ETP are working in 2013 on the project ≈20 persons involved at GANIL

  13. Budget : Total cost investment ~300k€ 237 k€ guaranteed by GANIL for 2013 to be completed in the 2014 request IPHC requested 90k€ from IN2P3 AP for the mechanic ANR (French Research Funding Agency) request for the gaz-filled mode to be submitted by the Saclay group (Ch. Theisen et al) Loan of material from LNL & GSI (cooled cabinet, racks, water distribution, Optical link to be carefully evaluated)

  14. Schedule (assuming that material from GSI arrive on Jan-Feb 2014) We request the host of AGATA until end of 2016 at least with ≥6 months beam time Gas-filled installation expected in mid-2015 GANISOL beam available for physics beginning of 2016

  15. Performance of the array J. Ljungvall (CSNSM) for the AGATA collaboration - Preliminary AGATA nominal 233 mm EXOGAM nominal 145 mm × ~ 1.25 × ~ 1.5

  16. More than efficiency , AGATA provides higher sensitivity b =12% × ~ 4.7 × ~ 12 gg performances under simulations
