GENERAL STRATEGY Basic Research in Physics in link with large scale facilities Researches into the fundamental laws of the Universe Co-Leader in France with CNRS (INSU & IN2P3), Universities Goals: 4 key questions and associated technology • What are the ultimate constituents of matter? • What is the energy content of the Universe? • How is the Universe structured? • What are nuclear matter self-organisation processes? Broader approach, large scale facilities and Cryotechnologies Goals: 2 specific technological topics • Superconducting Magnets • Particle Accelerators | PAGE 3
