Description

NIST has pioneered the development of x-ray spectrometers based on arrays of superconducting microcalorimeters. These thin-film sensors combine the high collecting efficiency of energy-dispersive detectors with the high resolving power of gratings or crystals. This topic focuses on the application of these spectrometers to problems in x-ray science. These problems include the determination of x-ray fundamental parameters, the detection and quantification of trace material components, the direct observation of ultrafast material dynamics, and better understanding the structural and electronic properties of complex materials relevant to emerging technologies. This research involves research collaboration between NIST groups using two facilities: the NIST superconducting spectrometer at Brookhaven National Laboratory’s National Synchrotron Light Source II, and the superconducting spectrometers at the NIST-Boulder, Colorado site, emphasizing fundamental parameters and ultrafast dynamics. Applicants interested in working primarily in Brookhaven, NY should apply under this research opportunity, with NIST NRC adviser Daniel Fischer. Applicants interested in primarily working in Boulder, CO should apply under a separate posting under the NIST NRC adviser Joel Ullom. Successful candidates will have the opportunity to conduct experiments at both sites and may also develop software and/or data analysis strategies shared between the two sites.
