We will give an introduction to the neutron scattering techniques relevant to the current session. Topics will include Reflectometry, Small Angle Neutron Scattering and Inelastic Scattering. We will briefly describe these methods and introduce various technical terms that will be used by the subsequent talks. These subsequent presentations will concentrate on scientific achievements or potentials of neutron scattering in biomaterials. We will also distribute handouts as technical references during session.
