THE LABORATOIRE LEON BRILLOUIN
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 program and collaborates closely with many scientists coming mainly from fundamental research laboratories, but also from applied research and industry. This leads to an annual rate of typically 180 publications in refereed scientific journals, and more than 150 communications in conferences and meetings.
LLB has also been opened to the international scientific community since many years. Several instruments have been built and are managed in collaboration with other countries : Germany, Austria, Belgium (up to 1995), Italy, Hungary, Russia.
