The Institut Max von Laue - Paul Langevin (ILL) is the leading international research facility for neutron science and technology. The reactor provides intense beams of neutrons that enable a large and diverse scientific community of visiting academic and industrial researchers to make new scientific advances and discoveries. The ILL suite of high‐performance instruments is constantly developed and upgraded aiming at improving operation, adapting the instrumentation to new research environments and offering new innovative techniques. Research at the ILL addresses critical challenges across areas ranging from the study of the origin of the Universe to the understanding of viral diseases in living organisms. The ILL devotes a large part of its activity to new energies and the environment.
Entered in the ESFRI Roadmap in 2006 with the ILL 20/20 project, ILL continuously developed programmes to support the overall upgrade of the instrument suit. By 2023, a two-decade campaign of improvements to the reactor and instruments will be complete, positioning researchers to carry out completely new types of experiments. The sixth protocol, recently signed by ILL’s Associate countries, extends the original agreement from 1971 for the period 2024 to 2033. In partnership with ILL’s Scientific Member countries, the commitment expressed in the protocol will ensure that European researchers have access to world-leading neutron scattering capabilities for break-through discoveries thus contributing to Europe’s competitiveness in areas addressing the most challenging questions facing our societies.
