RSoXS Data Reduction for ALS

The ‘ Data Reduction Panel’ is a skin on the general SAXS/WAXS data processing tool ‘NIKA’ written by Jan Ilavsky that facilitates convenient data browsing and streamlines the work flow of data processing for Resonant Soft X-ray scattering (RSoXS) conducted at beamline at the Advanced Light Source. The panel alters all settings appropriate for RSoXS processing and removes the need to interact with NIKA’s complex main panel. The goal is rapid, error-free data processing during data acquisition at the beamline that enables accurate qualitative assessment of scattering features and data quality.

This panel – originally developed by Elliot Gann (NSLS II) – has been adapted to Igor 7 and the latest NIKA release by Thomas Ferron (WSU) and further improves the workflow of RSoXS data processing. It was written such that it will continue to be compatible with future releases of NIKA.
