Bragg Edge Analysis for Transmission Imaging Experiments software tool: BEATRIX

Bragg Edge Analysis for Transmission Imaging Experiments, BEATRIX, is a new tool for performing data analysis of energy-resolved neutron-imaging experiments involving intense fitting procedures of multi-channel spectra. BEATRIX was developed to handle large, megapixel-sized data sets with high computing performance, addressed using the object-oriented C++ programming language and parallel processing. The tool is designed to provide rapid results, and it can be used on a range of computers, from personal laptops to highperformance computing clusters, with particular attention to memory management. This software is easily extendible to other spectral imaging applications. The use of BEATRIX is illustrated for a test specimen, providing spatially resolved 2D maps for residual strains and Bragg edge heights.
