2 What is EURISOL? Multi-user capabilities Up to 150 AMeV for 132Sn 235U
3 x 100 kW targets (REX-ISOLDE, SPIRAL ~ few kW HIE-ISOLDE ~ 10kW, TRIUMF ~ 50 kW) 1 x 4 MW converter (fission) target (SPIRAL-2 ~ 200kW, SPES ~ 100 kW) 3 x post-accelerators: 150 A.MeV 132Sn for secondary fragmentation 1-5 A.MeV Coulomb barrier nuclear physics ~ 1 MeV nuclear astrophysics ~ keV ground states, solid-state physics, etc. Cost: 1.3B€ 3 235U LINAC: H, D, He and A/q=2 ions up to 1 A GeV

(~400 person-yrs, ~ 33M€) Driver linac cavity IPN Orsay Driver requires half-wave resonators and spoke resonators 2 prototypes of 3-spoke cavity at =0.15 and =0.35 fabricated and successfully tested at 4.2 K Spoke cavity tuner 3

4 EURISOL Target Building
DESIGN STUDY High-dose irradiation tests of materials for 100 kW targets carried out at PSI and TRIUMF Innovative method of beam stripping by Lorenz stripping of H-

5 Liquid Hg converter concepts
DESIGN STUDY LOOP Curtain Prototypes tested at the IPUL Hg laboratory, Riga

6 Multi Mega Watt Target Layout
DESIGN STUDY 6 x “MAFF”-type individual UC target-and-moderator units new type of high-density UC compound tested on-line at PNPI, Gatchina

7 Beam Merging and ion source
DESIGN STUDY Prototype ARC-ECR built at Jyvaskyla Also: prototype RFQ coolers at ISOLDE and ORSAY Tests of EBIS, ECR at ISOLDE, LNL, GSI and BNL

8 Design of the post-accelerator
DESIGN STUDY SPIRAL-2 philosophy : Smooth beam dynamics Modular solution and simple cryostats, Separated vacuum Warm focussing (easier for alignment), Possibility to insert diagnostics Ease of tuning Main technical requirements: Only 2-gap cavities (high q/A acceptance) Max. accelerating fields 7.8 MV/m Nominal operation for A/Q between 4 and 8 8

12 Timescale for EURISOL EU FP6 EURISOL Design Study (~30M€) completed 2009 : Transition period; contacts with funding agencies and political bodies ~2012 : Application to be included in the ESFRI list (support from NuPECC & LRP necessary) Call for EU funded preparatory phase EURISOL Preparatory Phase Preparation of TDR Construction ~2025 : First Beam

13 The Transition Period (2010-2013)
The EURISOL project office (Y Blumenfeld chair, P Butler, A Facco, M Lewitowicz) setting up the EURISOL collaboration: (MOU in preparation) The EURISOL User Group (A. Bonaccorso chair ) The EURISOL Network in ENSAR (100 k€; Y. Blumenfeld leader) Requests to NuPNET for R&D through national funding agencies

14 Potential candidates to host
CERN LNL Legnaro 1. LINAC4 – 2013 10 kW direct target 2. Decision on SPL Potential candidates to host EURISOL GANIL + other sites? 1. Post-accelerator for SPIRAL-2 150 MeV/u 2. Phased approach to full EURISOL
