| Abstract Scope |
The complexity of the micro- and nano-structure of structural materials, often driven by response to applied stress, typically calls for detailed mapping of a sample. This begets increasingly large data volumes and the demand for more rapid measurements. At Sector 34-ID-E at APS, Argonne, a novel coded-aperture sample-scanning technique for conducting depth-resolved synchrotron Laue microdiffraction has been developed to provide significantly shorter scanning times. However, reconstructing data with this method, coupled with the increased rate of data acquisition, requires large compute resources and an automated user-friendly workflow to enable users to process data in real time. This presentation will introduce the principles of 3D Laue-diffraction microscopy, discuss how the high-performance-computing workflow can enable real-time depth reconstruction from coded-aperture data, and highlight recent efforts in streamlining the sending of information to and from Argonne’s HPC resources. |
