Join the ILL neutrons community

The ILL is a user facility welcoming scientists from all around the world to perform cutting-edge experiments in a variety of scientific and technological domains.

The unique properties of neutrons make them a powerful tool for unlocking the secrets of matter. Neutrons are used at the ILL to probe the microscopic structure and dynamics of a broad range of materials at molecular, atomic and nuclear level.

Alongside other tools for the characterisation of matter, neutrons make an invaluable contribution to our knowledge of materials and our understanding of the processes at work on different time and length scales.
