Assistant Physicist – Laue Microdiffraction

Argonne National Laboratory•Lemont, IL

21d•$94,486 - $147,399

About The Position

The Surface Scattering and Microdiffraction (SSM) group in the X-ray Science Division of the Advanced Photon Source at Argonne National Laboratory seeks an Assistant Physicist to support the operation, development, and scientific program of the 34-ID-E beamline. The beamline provides polychromatic and monochromatic micro- and nanofocused X-ray beams for spatially resolved studies of crystalline materials. Its core capability is 3D Laue microdiffraction for characterizing crystal structure, orientation, strain, and microstructural evolution. It also supports X-ray diffraction, fluorescence, and coherent X-ray techniques for materials research. The position supports beamline commissioning, operation, and continued development; develops advanced X-ray microdiffraction and microscopy methods, instrumentation, and scientific applications that use the upgraded APS source; and supports user experiments, including data analysis and interpretation. The physicist will conduct independent and collaborative research, contribute to expanding the beamline's user community and scientific capabilities, and publish and present results in peer-reviewed journals and at scientific conferences. Other duties may be assigned.

Requirements

Ph.D. in physics, materials science, engineering, or a closely related field.
Knowledge of X-ray diffraction, crystallography, and microdiffraction, with applications to materials characterization.
Experience with synchrotron X-ray techniques and experimental methods.
Scientific programming and computational skills for data analysis, experimental workflows, or instrument control.
Ability to analyze and interpret diffraction and materials-characterization data.
Demonstrated ability to work independently and collaboratively in a scientific team environment.
Ability to model Argonne’s core values of impact, safety, respect, integrity, and teamwork.
Interpersonal, oral communication, and written communication skills, and ability to interact with people at all levels within and outside the laboratory.
