  1. TheDESIRfacility at SPIRAL2 Désintégration, Excitation et Stockage d’Ions Radioactifs • Result of the SPIRAL2 workshop held at GANIL on July 2005: « Physics with low energy beams at SPIRAL2 » http://spiral2ws.ganil.fr/2005/lowenergy/program/presentations/ • Working groups: - Beam handling and beam preparation - Laser spectroscopy - Decay spectroscopy • An opened collaboration to promote ISOL beams at SPIRAL2 : B. Blank,M.J.G. Borge,P. Cambell, F. Herfurth,F. Leblanc,M. Lewitowicz,D. Lunney, O. Naviliat-Cuncic, G. Neyens,J.C. Thomas and …

  2. DESIR Physics program • Laser spectroscopy: collinear laser spectroscopy and b-NMR  moments, spins, radii, etc… • Fundamental interactions:  CVC, CKM matrix: 0+→ 0+ transitions exotic interactions like scalar or tensor currents electric dipole moments to test CP and T violation with e.g.Ra • Decay spectroscopy: p-p correlation, astrophysics, cluster emission, GT strength exotic shapes, halo nuclei, etc... • Solide state physics and other « applications » Call for LoI : May 2006

  3. Conclusions of the SPIRAL2 Workshop (July 2005) : M. Lewitowitcz “Physics with low energy beams at SPIRAL2” • Technical requirements • Anew experimental areaof about1500m2 • AHigh Resolution mass Separator(HRS) with a resolution ofM/M>5000 Proposed separation scheme: Low Resolution mass separator → RFQ cooler → HRS • Availability from day 1 Neutron-rich and neutron-deficient beams • More than one production target – ion source station(flexibility) Fast change of the mass setting 5.Extension of the current LIRAT beam line

  8. Synergies with FAIR/NuSTAR andLPCexpertise Beam preparation: cooler, traps, trap-assisted spectroscopy (MATS) Laser setups (LASPEC) Neutron detection (NCAP) New types of charged-particle and gamma detectors (e.g. LaBr3) Low-energy beam diagnostics

  9. Towards DESIR • DESIR project presented to the IN2P3 SC : 07/06 • DESIR LoI presented to the SP2 SAC : autumn 2006 • Proposals for experiments: spring 2007 • DESIR building design study: B.Blank, CENBG • DESIR HRS+cooler: D. Lunney, CSNSM • Laser ionization source: F. Le Blanc, IPN Orsay-ALTO • DESIR identification station: J.-C. Angelique, LPC (??) • Test bunch for diagnostic tools at LIRAT ? • Decay spectroscopy station: VS3 project (ANR 2006)

  10. Possible extension of LIRAT • Multi-beam facility (physics program  2011) • Tests and development for SPIRAL2 & DESIR LIRAT today Spec. b LPC Trap R&D SPIRAL2 1+ n+
