What is EURISOL?
LINAC: H, D, He and A/q=2 ions up to 1 A GeVLINAC: H, D, He and A/q=2 ions up to 1 A GeV
Up to 150 AMeV for 132SnUp to 150 AMeV for 132SnMulti-user capabilitiesMulti-user capabilities
235U3
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 fragmentation1-5 A.MeV Coulomb barrier nuclear physics~ 1 MeV nuclear astrophysics ~ keV ground states, solid-state physics, etc.
Cost: 1.3B€
SOME OUTPUT FROM DESIGN STUDY2005-2009 (~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

Prototypes tested at the IPUL Hg laboratory, Riga
DESIGN STUDY
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
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
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

Timescale for EURISOL
• EU FP6 EURISOL Design Study (~30M€) completed 2009
• 2010-2012 : 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
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

Potential candidates to host EURISOL
Potential candidates to host EURISOL
1. Post-accelerator for SPIRAL-2150 MeV/u
2. Phased approach to full EURISOL
1. LINAC4 – 201310 kW direct target
2. Decision on SPL
+ other sites?
