The Institut Laue-Langevin (ILL) is an international research centre at the leading edge of neutron science and technology. The Institute operates the most intense reactor source in the world, supplying neutrons to a suite of 40 high-performance instruments that are constantly upgraded. The ILL is funded and managed by France, Germany and the United Kingdom, in partnership with 10 other European countries. Some 1500 researchers from over 40 countries visit the ILL each year. Over 800 experiments, producing about 600 published papers, focus primarily on fundamental science in a variety of fields such as condensed matter physics, chemistry, biology, materials science and nuclear physics. The ILL instrument suite is continuously renewed and upgraded, ensuring that the Institute continues to play its dominant role in neutron research worldwide. Each instrument is designed to be state-of-the-art in its particular research field. ILL staff have expertise and experience in neutron production (reactor physics, reactor design and operation, cold and hot source design and operation…), neutron beam delivery (beam-tubes, neutron guides including supermirror guides), neutron optics (collimators, monochromators, neutron velocity selectors and choppers…), neutron detection and the complete range of neutron instruments for scientific research and its sample environment. The ILL is located in France but has 32% non-French scientists, engineers, and technical and administrative personnel. The ILL supports some 45 PhD students, registered at Universities across Europe.
