Description
Neutron reflectivity techniques offer several unique opportunities in materials research. However the possibility to fully take advantage of the data being taken depends entirely on the software available for analysis and visualization.
This limitation becomes obvious in terms of accessing off-specular data in momentum transfer space [1]. This is a specific capability, which has been proven to be needed for the analysis of hierarchical structures [2] as often found in soft matter [3] and 3D magnetic structures [4].
We present a new program package, that conducts generic 2D transformations to an orthogonal grid. It is specifically set for transferring instrument data into momentum transfer space. The method is designed and optimized for repeatable operations as they occur as standardized instrument settings being common on large scale facilities
In this contribution, we prove the operational capabilities of our package by showing artificial and real data from instruments at ORNL and ILL.
Further the limitations and an outlook for future capabilities and applications, such as coherent reflectivity [5] and true background reduction, will be presented.
