1 The low-energy facility at SPIRAL2 transport-energy (50 keV) exotic-nuclide beams for: For the DESIR Collaboration: D. Lunney, SPIRAL2 SAC, 29 January 2009 D ésintégration, E xcitation et S tockage d’ I ons R adioactifs decay spectroscopy - laser spectroscopy - ion / atom trapping - nuclear fine structure charge radii & moments masses, ion-purification weak interaction studies

2 The low-energy facility at SPIRAL2 Spokesperson: B. Blank GANIL liaison: J.-C. Thomas collaboration initiated during the first SPIRAL2 workshop, July 2005 series of meetings through to define DESIR: B. Blank, P. Campbell, F. Le Blanc, M.- J. Garcia-Borge, M. Lewitowicz, D. Lunney, O. Naviliat-Cuncic, G. Neyens, J.-L. Tain, P. Thirolf, J.-C. Thomas  over 110 scientists (lol & tp) D ésintégration, E xcitation et S tockage d’ I ons R adioactifs

3 low (no) energy & precision measurements four-year observationconsiderably less… Increased production for two nuclear structure paradigms:  intensity for specific reactions  chart the terra incognita ISOL:good beam quality TRAP:long observation time decay kinematics beam preparation NIST Jackson Pollock beam preparation DESIR:(precise) knowledge of global observables and detailed spectroscopy
