1 Proposal for a high-intensity, light and heavy ion facility in Europe ECOS-LINCE: European LINAC CENTER Prepared by Ismael Martel (Huelva University)

2 This document was prepared by the ECOS (European COllaboration on Stable ion beams) working group, in order to describe the research perspectives with high intensity stable ion beams, to help categorize existing facilities and to identify the opportunities for a dedicated new facility in EUROPE ECOS Working group: Faiçal Azaiez (Chair) (IPNO Orsay) Giacomo de Angelis (LNL Legnaro) Rolf-Dietmar Herzberg (Liverpool) Sigurd Hofmann (GSI Darmstadt) Rauno Julin (Jyväskylä) Marek Lewitowicz (GANIL Caen) Marie-Helene Moscatello (GANIL Caen) Anna Maria Porcellano (LNL Legnaro) Ulrich Ratzinger (Frankfurt) HIGH INTENSITY STABLE ION BEAMS IN EUROPE

3 …“The long-term goal for a new dedicated high intensity stable ion beam facility in Europe, with energies at and above the Coulomb barrier, is considered to be one of the important issues to be discussed in the next Long Range Plan of the nuclear physics community.”… IV: Concluding remarks and recommendations ECOS working group conclusions

4 LINCE; high-intensity superconducting LINAC - Wide range of ions, from protons to Uranium - Wide range of energies, up to 10 A MeV for 238U - High Intensity accelerator (1 mA light ions  10 p  A heavy ions) LINCE: energy booster using heavy-ion synchrotron: - 50 MeV/u for light ion species - 200 MeV for deuterons.

7 Material research for energy production Fusion energy research: aiming at qualifying advanced materials resistant to extreme conditions, specific to fusion reactors like ITER.
