1 EURISOL Peter Butler University of Liverpool on behalf of the EURISOL Project Office

2 What is EURISOL? LINAC: H, D, He and A/q=2 ions up to 1 A GeV Up to 150 AMeV for 132 Sn Multi-user capabilities 235 U 3 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 132 Sn 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 SOME OUTPUT FROM DESIGN STUDY (~400 person-yrs, ~ 33M) 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 Driver linac cavity IPN Orsay

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

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

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

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

8 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 Design of the post-accelerator 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 DESIGN STUDY

9 Comparison of yields: Kr

10 Secondary fragmentation of 132 Sn beam at GSI D. Loureiro et al. Zakopane proceedings (2008) DESIGN STUDY

11 Expected reach of EURISOL fragmentation of 132 Sn heaviest stable New Pd 125 r-process & drip-line 132 Sn: GSI present: 10 3 /sFAIR, FRIB: 10 8 /sEURISOL: /s New Pd 125 r-process & drip-line COFRA Karlsruher Nulidkarte 2006

12 Timescale for EURISOL EU FP6 EURISOL Design Study (~30M) completed : 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 ( ) 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 CERN GANIL LNL Legnaro Potential candidates to host EURISOL Potential candidates to host EURISOL 1. Post-accelerator for SPIRAL MeV/u 2. Phased approach to full EURISOL 1. LINAC4 – kW direct target 2. Decision on SPL + other sites?
