N1 - Funding Information: During the recent CHESS upgrade, beamline ID4B was specifically designed to enable HDRM measurements. The research program at ID4B, supported by the NSF Division of Materials Research, is called “Q-Mapping for Quantum Materials” or “.” The beamline features a permanently installed 6-Megapixel Pilatus3 area detector, a psi-circle goniometer for full control of sample orientations, several low-temperature and UHV sample environments (), and high-performance computing resources dedicated to data analysis. The bright undulator beam is monochromated using diamond reflections in a double-crystal design, with an unusually wide range of accessible energies spanning 5 keV to 70 keV. HDRM measurements are typically performed between 30 keV and 70 keV, but the beamline is also capable of lowering the energy to perform complementary resonant elastic X-ray scattering (REXS) studies on the same sample volumes during the same beamtime. This unique configuration allows to function like a “zoom lens” in reciprocal space, first taking a wide survey with high-energy X-rays to identify ordering wavevectors and then focusing in on specific features for more detailed study. These capabilities will offer new and precise insight into the quantum world. 2 2 Funding Information: In addition to the in-situ structural characterization techniques cultivated for use at CHESS, Energy Dispersive Diffraction (EDD) sits primed for use not only as an academic and scientific measurement, but also as an engineering tool for use in the private sector to non-destructively investigate residual strains in structural components. Building upon the pioneering InSi t µ program, funded by the Office of Naval Research , the MSN-C seeks to adapt the power of synchrotron-based techniques to answer some of the most important materials manufacturing and performance challenges facing the Department of Defense (DoD) and their original equipment manufacturers (OEMs). To this end, a robust infrastructure of sample staging, on-the-fly data reduction software packages, and enhanced scientific support from domain scientists (structural material scientists and mechanical engineers) relaxes the need for a user to become an X-ray expert or even X-ray proficient. In this new paradigm, CHESS and AFRL scientists work with DoD researchers and OEMs to plan experiments and deliver fully reduced residual strain maps (and, in special cases, calculated residual stress maps), in addition to enhanced support with interpretation and model interfacing when appropriate.
