Abstract

Synchrotron light source facilities worldwide generate terabytes of data in numerous incompatible data formats from a wide range of experiment types. The Data Analysis WorkbeNch (DAWN) was developed to address the challenge of providing a single visualization and analysis platform for data from any synchrotron experiment (including single-crystal and powder diffraction, tomography and spectroscopy), whilst also being sufficiently extensible for new specific use case analysis environments to be incorporated (e.g. ARPES, PEEM). In this work, the history and current state of DAWN are presented, with two case studies to demonstrate specific functionality. The first is an example of a data processing and reduction problem using the generic tools, whilst the second shows how these tools can be targeted to a specific scientific area.

Keywords: DAWN; analysis; software; visualisation.

Figure 1
Screenshot of the DAWN Data Browsing perspective showing the radial profile of a powder diffraction image being peak fitted. The labelled components are: (a) the Project Explorer, for keeping track of files of interest; (b) the Data view, for selecting datasets or slices of datasets for display; (c) a plot of the selected data slice; (d) the colour mapping tool for adjusting the image contrast; (e) result of the radial integration tool (over the region specified by the red sector); and (f) the result of using the peak fitting tool to identify the peaks in the radial profile, and display their parameters.

Figure 2
The Data Browsing perspective. In this case the data window has been used to run mathematical expressions on the data to produce the corrected images, as shown. The image and the view at the bottom left show the region editor tool for selecting regions of interest, which are used in the data reduction of this sample (shown in red and green).

Figure 3
The PEEMA perspective. The custom PEEM analysis view is situated at the top right of the screenshot, with the other images, colour mapping tool and image explorer being generic views which have been reused.
