Prototyping und wissenschaftliche Beispiele

GISAS is both an important topic for modern nano-science and strong in-house competence for the PNI partners. This means that several existing software packages at the proposing centres can be contributed, expediting the efficient development of exemplary software. The main task is to merge the subunits into one user friendly software tool using an open architecture and allowance for continuous further development, and thereby to meet the needs of the non expert users from chemistry, biology, or engineering materials backgrounds. This will cover neutron and X-ray applications equally well and allow for multi-probe analysis. Users of the PNI instruments REFSANS (GKSS), MARIA (JCNS), KWS1 and KWS2 (JCNS), V6 and V18 (HZB), NANO (ANKA), MiNaXS and BW4 (DESY) will profit immediately from such an initiative.

For GISAS, representative 3D images of surfaces, interfaces, or domain structures will be produced depending on the model chosen: nano-particles on surfaces, fractal interface morphologies, magnetic domains etc. Recently, a JCNS workshop on “modelling and data analysis for grazing incidence and off-specular scattering”, enabled an overview of the main challenges for their application to be clearly identified. Identified to be of particular importance was the development of modelling methods especially the Distorted Wave Born Approximation (DWBA), and also the bringing together of the various international efforts in theory and experiment through extended cooperation between HGF centres and external scientists. Indeed, if the advances in modelling and analysis can be brought into a useable package then this would have the immediate impact of disseminating the most advanced techniques directly to the broader community.
