  • ILIASILIAS : Integrated Large Infrastructures for Astroparticle ScienceILIAS is an Integrated Infrastructure Initiative (IA) proposed for funding by European Union within the 6th Framework Programme. It is based on the cooperation of many EU institutions operating in the sector of Astroparticle physicsFrance : Commissariat a lEnergie Atomique, Centre National de la Recherche ScientifiqueItaly: Istituto Nazionale di Fisica Nucleare, Istituto di Fotonica e Nanotecnologie Trento, European Gravitational Observatory Germany: Max Planck Institut fr Kernphysik, Technische Universitt Mnchen, Max Planck Institut fr Physik Muenchen, Eberhardt Karls Universitt TubingenSpain: Zaragoza UniversityUK: Universities of Sheffield, Glasgow, and LondonCzech Rep.:Czech Technical Univ. in Prague Denmark: University of Southern Denmark Netherland: Leiden UniversityFinland: University of Jyvskyl Slovakia: Comenius University BratislaviaGreece: Aristot University of Thessaloniki ILIAS is born with the coordination of APPEC (AstroParticle Physics European Coordination)IDM2004 Edinburgh, 10-sep-04
