Title: The EURISOL Project

Abstract

The European plan for Radioactive Beam Facilities aims for the construction of two 'next generation' facilities: FAIR, a projectile fragmentation facility to be located at GSI, Darmstadt, Germany, and EURISOL, a high power ISOL facility. The basic layout of EURISOL will be described. The most challenging technical parts of such a facility are currently being designed and protoyped within a pan-European design study supported by the European Union. The organization of this study will be outlined and the first conclusions will be discussed.

  • Next generation facilities such as those designed in SPIRAL-2 and EURISOL projects require dedicated radioactive ion sources. Indeed, the ion source must be capable of operating under the very strong radiation generated by the primary beam in the production target. In the framework of the SPIRAL-2 design study, realistic and efficient solutions have been studied to face these unprecedented irradiation constraints. The considered options will be described and argued. In particular, considering forced electron beam induced are discharge-type ion sources, the reasons to start the development of a new prototype, the ionization by radial electron neat adaptation (IRENA) ion source,more » will be presented. The IRENA ion source is based on the electron beam generated plasma ion source. The design of the first prototype will be presented and discussed.« less
  • The so-called beta-beam concept for accelerator-driven neutrino experiments envisages the production of a pure beam of electron neutrinos (or their antiparticles) through the beta-decay of radioactive ions circulating in a high-energy storage ring. The conceptual design of a beta-beam facility is ongoing within the framework of the EURISOL Design Study. The required acceleration and accumulation of an unprecedented number of ions brings many challenges. Those most recently addressed are presented in this paper together with a brief overview of some of the salient features of the current design machine by machine.
  • To take up the challenging issue of supplying a plasma ion source able to produce radioactive beams under extreme SPIRAL2 and EURISOL irradiation conditions, a research and development program has been initiated to work out ionization by radial electron neat adaptation (IRENA) ion source. Based on the electron beam generated plasma concept, the ion source is specifically adapted for thick target exploitation under intense irradiation. A validation prototype has been designed, constructed, and tested. First results obtained will be presented and commented. IRENA potential will be discussed, particularly in the framework of multimegawatt EURISOL.
  • In-flight separation and Isotope Separation On -Line (ISOL) are the two main methods for producing radioactive ion beams. A brief description of the ISOLDE facility at CERN, which has accumulated 50 years of experience of the ISOL technique is given. The HIE -ISOLDE project, which is a major upgrade of the energy and intensity of ISOLDE is described. The long-term plans for ISOL in Europe culminate with the EURISOL facility which has been developed within a pan-European design study. The EURISOL concept resulting from this study is presented.
  • The EURISOL (The EURopean Isotope Separation On-Line Radioactive Ion Beam) project aims at designing a facility for producing high intensity radioactive ion beams, with unprecedented (two to three orders of magnitude higher) intensities, compared to the majority of the worldwide existing RIB facilities. For this purpose, a proton beam of energy 1 GeV and intensity up to 4 mA impinges on a liquid mercury target (the converter). The high neutron fluxes (in excess of 10{sup 15} n cm{sup -2} s{sup -1}) produced by spallation nuclear reactions in the converter induce fission on {sup 235}U targets surrounding the liquid mercury converter.more » In order to attain the intended high intensity radioactive ion beams, the appropriate configuration (geometry and materials) of the target unit components (converter, fission targets, moderators, reflectors) must be determined, to attain the highest possible fission rates in the uranium targets (in excess of 10{sup 15} fissions per second). The extremely high neutron and photon fluxes resulting from the operation of the target unit impose, for radiological protection and safety purposes, a careful assessment of the dose rates in the surrounding areas. Activation of the structural components must be studied. Thick shielding barriers must be designed. In this work, the so-called MAFF inspired target configuration, allowing a versatile operation, maintenance, remote control and storage of the fission targets is considered. The results obtained using the state-of-the-art Monte Carlo codes MCNPX and FLUKA are presented. The neutronics, dose rate, shielding and activation calculations, needed for radiological protection and safety assessment purposes are discussed.« less
