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…
Phase retrieval for Bragg coherent diffraction imaging at high X-ray energies
Siddharth Maddali, Marc Allain, Wonsuk Cha +6
Coherent X-ray beams with energies keV can potentially enable three-dimensional imaging of atomic lattice distortion fields within individual crystallites in bulk polycry…
Multi-element Germanium Detectors for Synchrotron Applications
Abdul K. Rumaiz, Anthony J. Kuczewski, Joseph Mead +14
We have developed a series of monolithic multi-element germanium detectors, based on sensor arrays produced by the Forschungzentrum Julich, and on Application-specific integrated c…
