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.

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
