Laboratoire Léon Brillouin (LLB)

The Laboratoire Léon Brillouin (LLB) is a french laboratory supported jointly by the Commissariat à l’Energie Atomique (CEA) and the Centre National de la Recherche Scientifique (CNRS). Its aim is to carry out research on the structure and dynamics of condensed matter using neutron beams supplied by the reactor Orphée. It is situated in the CEA/Saclay research centre.

The large domain of application and the maturity of neutron scattering have made it a modern technique indispensable to any research at the microscopic level (structure and dynamics) in fields as various as condensed matter physics, chemistry, biology and materials science. In particular, neutron scattering is one of the major technique for the study of soft matter (H/D contrast variation method), magnetism, dynamics (in the time range 10-8 to 10-12s), and liquids. In industrial problems, advantage is taken of the deep penetration of neutrons in matter for non-destructive studies.

The LLB carries out its own scientific research programme and collaborates closely with many scientists coming mainly from fundamental research laboratories, but also from applied research and industry.

LLB has also been opened to the international scientific community since many years.
