Abstract

This article presents an overview of the recent developments in SANS and GISANS instrumentation at LLB-Orphée. SANS is a well-known technique, especially well adapted for research in material sciences, soft matter and nanosciences, which has proved to be particularly powerful to study complex systems, from nm to μm, taking full advantage of isotopic labelling and contrast variation methods. In this article, two instruments will be described in some details: TPA, the new VSANS (Very-Small Angle Neutron Scattering) instrument which is now fully functional and PA20, the new SANS spectrometer under construction, which will extend LLB’s capabilities in terms of SANS for magnetism with a polarized neutron option and Grazing Incidence SANS (GISANS).
