RIB Science : A Myriad of Opportunities
RIB Facilities : A Worldwide Effort
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.
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.
The EURISOL Concept(based on 5th framework RTD)
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.
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€

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.

• Higher and harder neutron spectrum: enhanced fission densities (4 times larger).
• Technical difficulties to implement.

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
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
