Interfaces are integral to major research fields in chemistry, physics, biology, and engineering science, where Swedish scientists have made significant contributions. Progress within this field has provide Swedish industry the bases for successful products in modern electronics, spintronics and nanoscience products, bio-based materials, drug deliveryand biomedical devices, coatings, lubrication and surface processes including cleaning. The grazing incidence small-angle neutron scattering (GISANS) technique enables the full structure and morphology of surfaces, films, and interfaces to be investigated. The ESS provides a first and world-unique opportunity since it’s very high brilliance will allow GISANS measurements that are at least an order of magnitude faster than at existing sources, and thereby allow the technique to become a crucial and widely utilized tool for surface science.
A concerted Swedish initiative to prepare for the design and construction of a GISANS instrument, SAGA, at ESS has been developed during the last couple of years thanks to the close collaboration and joint efforts of all the main Swedish research institutions with neutron activities. We now want to welcome you to a web symposium on the GISANS technique, featuring two pioneers on the techniques Dr. William A. Hamilton, USA and Professor Peter Müller-Buschbaum, Germany. We will also provide an updated on the SAGA initiative and some recent progress in the application of GISANS.
Information about the BornAgain interactive tutorial
Bornagain is an open-source package that simulates and fits neutron and x-ray grazing-incidence small-angle scattering. It implements the distorted-wave Born approximation (DWBA) as the physical model for the scattering process and allows users to simulate multilayer samples with smooth or rough interfaces. Additionally, it includes a vast catalogue of nanoparticle form factors, which can be arranged in different 3d configurations.
The tutorial will introduce the two main use cases of bornagain: GISA[X|N]S Simulations and GISA[X|N]S data fitting. A series of short video-tutorials will be made available for participants to watch before the interactive session. The video tutorials will cover the simulation of a GISAXS experiment and the fitting of mock data, while the interactive session will focus on fitting data coming from a real experiment (Thanks to Nicolo Paracini & Marité Cardenas).
In order to attend the interactive session, participants are asked to download and install bornagain (https://www.bornagainproject.org/download/) and contact Åsa Grunning at asa.grunning@fsi.lu.se beforehand to get the links to the video tutorials prior to the event.
If problems arise during the installation of bornagain, please contact Juan Carmona directly at j.carmona.loaiza@fz-juelich.de
