Grazing incidence scattering methods using neutrons provide unique opportunities in surface science. However, till now mostly specular neutron reflectometry is used to extract isotope densities or the magnetic induction profiles along the direction normal to interfaces. Off-specular and grazing incidence small angle scattering (GISANS) can provide additional information about correlations in the plane of interfaces. While off-specular scattering is easily implemented on existing neutron reflectometers, GISANS would benefit from dedicated instrumentation, as it has distinct requirements with respect to resolution and is flux hungry.
The European spallation source (ESS) has identified a dedicated GISANS instruments as one of their capability gaps and the Swedish research community has responded top this with a concerted effort to push for a project to design such an instrument. The Swedish research council is financing the design phase.
The SAGA satellite workshop brings together international scientists and officials to drive the development of a GISANS instrument for the ESS. During this workshop the specifications of the instrument will be discussed and brought into context with different design options. Emphasis will be on practical experience with conducting GISANS experiments and their application on recent challenges in surface science.
During the workshop we offer the possibility for a visit of the MLZ and the instrument RefSANS, which is currently the only dedicated GISANS instrument in the world.
There is no registration fee for the meeting and lunch and dinner will be provided to registered participants. For site entrance a national ID or passport is required (drivers license etc. are not accepted).
Registration for this event is currently open.
