The Present and the New HFR-Petten SANS Facility

Abstract

A great deal of the properties of materials is influenced by phenomena taking place in the sub-micron region. Scattering techniques play an important role for obtaining structural information. Small-Angle Neutron-Scattering (SANS) is one such scattering technique by which one can obtain structural information of the material being studied. Structural information here means size and form of the object under investigation. In a SANS experiment one collects data as a function of the momentum transfer which is proportional to the scattering angle. The probed length scales by SANS varies from a few nanometres to 600 nanometres. In this paper we present the present status of the SANS facility with a preliminary measurement on core-shell particles. Furthermore, we look at the future perspectives of upgrading the facility to enhance the neutron flux at the sample position.
