Description
The SNAP diffractometer at SNS is highly re-configurable, featuring movable detectors, choppers, and optional neutron optics, introducing challenges in automated data reduction. The complexities of this data orchestration necessitated the development of the ongoing SNAPRed software. SNAPRed addresses this by defining unique Instrument States based on the instrumental configuration. A streamlined workflow for rapid, standardized calibration, accompanied by metrics for calibration quality, is a key feature. Pressure cells (“containers”) impact background and attenuation with wavelength-dependent effects. SNAPRed integrates existing approaches to manage these challenges. User experience (UX) is prioritized, balancing accessibility for novices with advanced controls for experts. Performance is optimized to support real-time Rietveld analysis by the end user, supported by a “lite” mode for faster data processing without loss of diffraction resolution. The software standardizes the reduction workflow, capturing all parameters, metadata, and processes for complete provenance of the reduced data.
