INSIGHT: in situ heuristic tool for the efficient reduction of grazing-incidence X-ray scattering data

Abstract

INSIGHT is a Python-based software tool for processing and reducing 2D grazing-incidence wide- and small-angle X-ray scattering (GIWAXS/GISAXS) data. It offers the geometric transformation of the 2D GIWAXS/GISAXS detector image to reciprocal space, including vectorized and parallelized pixel-wise intensity correction calculations. An explicit focus on efficient data management and batch processing enables full control of large time-resolved synchrotron and laboratory data sets for a detailed analysis of kinetic GIWAXS/GISAXS studies of thin films. It processes data acquired with arbitrarily rotated detectors and performs vertical, horizontal, azimuthal and radial cuts in reciprocal space. It further allows crystallographic indexing and GIWAXS pattern simulation, and provides various plotting and export functionalities. Customized scripting offers a one-step solution to reduce, process, analyze and export findings of large in situ and operando data sets.

“…The collected GIWAXS data were further processed by the Python-based heuristic tool INSIGHT. 47 The correction of SDD induced by the chamber thermal expansion was realized by calibrating the (111) Cu Bragg reflex to 3.0103 Å –1 (2θ = 43.297°). Cake cuts of the 2D GIWAXS data for pseudo-XRD were done with the limits of χ = [0, 90°] and q = [1.49, 4.01] Å –1 .…”
