The Future of EURISOL Results from the Design Study Initiatives for the Future We acknowledge the financial support of the European Community under the FP6 “Research Infrastructure Action - Structuring the European Research Area” EURISOL DS Project Contract no. 515768 RIDS .

The Current European Situation The Previous LRP NuPECC recommends the construction of 2 ‘next generation’ RIB infrastructures in Europe, i.e. one ISOL and one in-flight facility. The in-flight machine would arise from a major upgrade of the current GSI facility: FAIR, while EURISOL would constitute the new ISOL facility The Current European Situation Construction of intermediate generation facilities: SPIRAL2, HIE-ISOLDE, SPES and of FAIR has begun or is about to begin. Design and prototyping of the most specific and challenging parts of EURISOL has been carried out in the framework of EURISOL_DS. EURISOL must go beyond FAIR and offer the best of both worlds : ISOL and Fragmentation

What is EURISOL?

The Eurisol Layout

New baseline scheme with extended capabilities 2 injection lines for H,D, He and A/q=2 ions SARAF scheme up to 60 MeV/q IPNO scheme from 60 to 140 MeV/q CEA scheme from 140 to 1000 MeV/u cw beam splitting at 1 GeV (1 line 4 MW + 3 lines 100 kW) Total length of the linac: ~240 m 4 MW H- B stripper RFQ 176 MHz Elliptical 704 MHz HWR 176 MHz 3-SPOKE 352 MHz 1 GeV/q H-,D- =0.09 =0.15 =0.03 =0.47 =0.65 =0.78 100 kW H+, 3He2+ H+,D+, 3He++ 1.5 MeV/u 60 MeV/q foil stripper 140 MeV/q >200 MeV/q D, A/q=2 10 36 31 63 97 EURISOL task 7 : Alberto Facco LNL-Legnaro

Beam Preparation

Design of the post-accelerator SPIRAL-2 philosophy : Smoothest beam dynamics (regular FDO lattice, low number of -sections), Modular solution and simple cryostats, Separated vacuum (safety with FP), Warm focusing (easier for alignement), Possibility to insert diagnostics at each period, 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 EURISOL Task 6 : Marie-Hélène Moscatello - GANIL

Timescale for EURISOL 2010-2012 : Transition period; contacts with funding agencies and political bodies 2012 : Application to be included in ESFRI list (support from NuPECC & LRP necessary) 2013 : Call for preparatory phase 2014-2017 : EURISOL Preparatory Phase 2017-2019 : Preparation of TDR 2020-2025 : Construction 2025 : First Beam

The “Transition” Period (2010-2013) The EURISOL project office: Y.B., Peter Butler, Alberto Facco, Marek Lewitowicz The EURISOL collaboration: (MOU between all laboratories interested in furthering EURISOL; in preparation) The EURISOL User Group (Established with elected executive committee; will federate scientific community and update physics case; A. Bonaccorso, chair ) The EURISOL Network in ENSAR (included in ENSAR application; will coordinate EURISOL focused R&D at current facilities and fund Town Meetings; 150 KE; leader Y. Blumenfeld) The EURISOL work package in TIARA : (included in TIARA application; Define and Prepare R&D platforms for EURISOL; up to 500 KE; leader S. Bousson – Orsay) Requests to NuPNET for pan-European funded R&D through national funding agencies (approx 1ME each – at most 1 to be funded) Liquid metal target tests Beam splitter ECRIS beam merger EC support for global projects: Possibility of EC support up to 1 ME to expand EURISOL into a global (worldwide) project; suggestion from Brussels still to be investigated.
