The LLB is a service-providing laboratory that also develops its own
scientific research. One of its roles is the
design, construction, and operation of
neutron spectrometers installed around the Orphée reactor in Saclay.
These are mainly used for the study of condensed matter.
The scientific activities of the laboratory can be classified in three
fields of equal importance: physical-chemistry, structural and phase
transition studies, magnetism and superconductivity.
