  1. EURISOL: European Collaboration towards the ultimate ISOL facility Yorick Blumenfeld IPN – Orsay 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 .

  2. RIB Science : A Myriad of Opportunities

  3. RIB Facilities : A Worldwide Effort

  4. THE EUROPEAN PLAN NuPECC and the OECD GSF recommend 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 Construction of FAIR will start soon. The EURISOL concept was found to be too challenging for immediate implementation; so a road map based on pan-European expertise and emerging projects was devised.

  5. The EURISOL Road Map • Vigorous scientific exploitation of current ISOL facilities : EXCYT, Louvain, REX/ISOLDE, SPIRAL • Construction of intermediate generation facilities: SPIRAL2, HIE-ISOLDE, MAFF, SPES • Design and prototyping of the most specific and challenging parts of EURISOL in the framework of EURISOL_DS.

  6. The EURISOL Concept(based on 5th framework RTD)

  7. The Main Challenges • Design a 5MW; 1GeV proton driver with additional capability of 200 AMeV deuterons and A/Q=2 Heavy Ions; build and test prototypes of the cavities. • Design a liquid Hg converter which will accept 5 MW of beam power. • Design a UCx target which will make the most efficient use of the neutrons produced. • Evaluate the safety constraints of the above set up. • Design an efficient multi-user beam distribution system. • Design a superconducting HI LINAC capable of accelerating 132Sn up to 150 AMeV • Investigate technologies for the instrumentation of the future • Provide a conceptual study for a beta-beam neutrino facility.

  8. The EURISOL_DS in the 6th framework • A bottom-up process based on a call to laboratories • No leading country • Detailed engineering oriented studies and technical prototyping work • 21 participants from 14 countries • 21 contributors from Europe, Asia and North America • Total Cost : 33 M€ • Contribution from EU : 9.16 M€

  9. Driver accelerator Legnaro – Orsay - GANIL 1 GeV 5 MW proton beam 3He at 2 GeV, deuterons at 250 MeV, heavy ions of A/Q=2 at 125AMeV

  10. Reflector UCx/BeO Target Reflector Protons 16 cm Hg Target UCx/BeO Target Protons Target container 4 cm Hg Jet 68 cm UCx/BeO Target Reflector Reflector 40 cm High power target • Hg-loop: Reasonable charged particle confinement and power densities. • High neutron fluxes in the fission target, confined within the assembly. • Proven design (SNS and ESS), technically simpler concept. • Hg-jet: Very large high-energy proton escapes: Radioprotection issues, charged-particle contamination in the fission target . • Higher and harder neutron spectrum: enhanced fission densities (4 times larger). • Technical difficulties to implement. CERN – Legnaro – PSI – IPUL (Latvia)

  11. Beta-Beamsa collaboration between Nuclear and Particle communities 6He, 18Ne From: Mats Lindroos, CERN

  12. Technical Challenges abound, but the largest has yet to be tackled: the location? The Design Study will investigate the implementation and cost of EURISOL in these 3 hypotheses

  13. CONCLUSIONS • A 4 year Design Study for a next generation European ISOL facility is being carried out by 21 laboratories in 14 countries, supported by a large community of scientists. • It makes use of the areas of expertise of these laboratories, developed in particular from the exploitation of current facilities and the building of “intermediate generation facilities”. • It involves the neutrino community through the beta-beam feasibility study. • Strongly supportive of the “International ISOL Collaborative working group” proposed by Mats Lindroos and Alan Shotter. • Investigation of potential sites will be undertaken shortly • The next step should be a preparatory construction phase. • Construction could begin around 2013. • You are cordially invited to attend the EURISOL Town Meeting at CERN, Nov 27-28; www.eurisol.org
