The Institut Laue-Langevin is an international research centre at the leading edge of neutron science and technology. As the world’s flagship centre for neutron science, the ILL provides scientists with a very high flux of neutrons feeding some 40 state-of-the-art instruments, which are constantly being developed and upgraded. As a service institute ILL makes its facilities and expertise available to visiting scientists. Every year, about 1400 researchers from over 40 countries visit the ILL and 640 experiments selected by a scientific review committee are performed. Research focuses primarily on fundamental science in a variety of fields: condensed matter physics, chemistry, biology, nuclear physics and materials science, etc. Whilst some are working on battery design, fuels and catalysts, plastics and pharmaceuticals, others are looking at biological processes at cellular and molecular level. Still others may be elucidating the physics that could contribute to the electronic devices of the future. ILL can specially tailor its neutron beams to probe the fundamental processes that help to explain how our universe came into being, why it looks the way it does today and how it can sustain life. The ILL also collaborates closely and at different levels of confidentiality with the R&D departments of industrial enterprises.
