BraggNN: Fast X-ray Bragg Peak Analysis Using Deep Learning
Zhengchun Liu, Hemant Sharma, Jun-Sang Park +5
X-ray diffraction based microscopy techniques such as High Energy Diffraction Microscopy rely on knowledge of the position of diffraction peaks with high precision. These positions…
Big Data Staging with MPI-IO for Interactive X-ray Science
Justin M. Wozniak, Hemant Sharma, Timothy G. Armstrong +3
New techniques in X-ray scattering science experiments produce large data sets that can require millions of high-performance processing hours per week of computation for analysis.…
High-energy coherent X-ray diffraction microscopy of polycrystal grains: first steps towards a multi-scale approach
Siddharth Maddali, Jun-Sang Park, Hemant Sharma +7
We present proof-of-concept imaging measurements of a polycrystalline material that integrate the elements of conventional high-energy X-ray diffraction microscopy with coherent di…
Microstructure analysis of bismuth absorbers for transition-edge sensor X-ray microcalorimeters
Daikang Yan, Ralu Divan, Lisa M. Gades +16
Transition-edge sensors (TESs) as microcalorimeters offer high resolving power, owning to their sharp response and low operating temperature. In the hard X-ray regime and above, th…
Eliminating the non-Gaussian spectral response of X-ray absorbers for transition-edge sensors
Daikang Yan, Ralu Divan, Lisa M. Gades +16
Transition-edge sensors (TES) as microcalorimeters for high-energy-resolution X-ray spectroscopy are often fabricated with an absorber made of materials with high Z (for X-ray stop…
Influences of Granular Constraints and Surface Effects on the Heterogeneity of Elastic, Superelastic, and Plastic Responses of Polycrystalline Shape Memory Alloys
Harshad M. Paranjape, Partha P. Paul, Hemant Sharma +5
Deformation heterogeneities within microstructures of polycrystalline shape memory alloys (SMAs) during superelastic stressing are studied using both experiments and simulations. I…
