2. RIB Science : A Myriad of Opportunities

3. RIB Facilities : A Worldwide Effort

4. 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 THE EUROPEAN PLAN 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 5 th 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 132 Sn 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 6 th 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 1 GeV 5 MW proton beam 3 He at 2 GeV, deuterons at 250 MeV, heavy ions of A/Q=2 at 125AMeV Legnaro – Orsay - GANIL

10. 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. Protons Reflector Hg Jet UCx/BeO Target 40 cm 4 cm 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. Hg Target Reflector Target container UCx/BeO Target Protons 68 cm 16 cm High power target CERN – Legnaro – PSI – IPUL (Latvia)

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

12. Technical Challenges abound, but the largest has yet to be tackled: the location? Admin istrati on / Stay at GANIL 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.
