Assistant Beamline Scientist – High-Energy X-ray Diffraction

Website advancedphoton Argonne National Laboratory

The Structural Science group (SRS) in the x-ray Science Division (XSD) at the Advanced Photon Source (APS) enables world-class research using high-energy x-rays by developing cutting edge instrumentation and techniques, and pursuing research in the physical, chemical, environmental, and materials sciences. To accomplish this mission, SRS will operate five independent beamlines in the photon energy range between 26 to 120 keV after the upgrade of the APS. We are currently seeking a beamline scientist to support the high-energy x-ray beamlines operated by the SRS group. The beamlines are dedicated to in situ and operando diffraction and total scattering experiments for pair distribution function (PDF) analysis in combination with multimodal approaches, such as small angle scattering, Raman spectroscopy, fluorescence, Compton scattering, or Residual Gas Analysis. The APS-U Enhanced beamline 11-ID-D will enable novel experiments with highest flux, sub-micrometer focused beam, and extreme total scattering including the small angle scattering regime, thus leveraging the strength of the most brilliant high-energy storage ring world-wide.

The successful candidate will work with a highly motivated and diverse team to support user experiments and develop new techniques, sample environments, and/or novel data acquisition strategies for the beamlines at 11-ID.

Position Requirements

We expect the following knowledge, skills and experiences

  • Experience in conducting in situ and operando diffraction experiments
  • Experience with Python and/or C/C++
  • Knowledge of diffraction theory, crystallography, and approaches to advanced analysis including structural refinement and modeling
  • Skill in oral and written communication of scientific results and experimental plans
  • Ability to work well in a team environment
  • Flexibility and fast adaptation to new situations
  • Role model Argonne’s Core Values.
  • Understand, value, and promote diversity.

To complement our team, we are looking for one or more of the following qualifications:

  • Expertise in small angle scattering
  • Instrumentation design including hands on realization
  • Development of scripts for advanced data acquisition and analysis strategies
  • Expertise in x-ray optics
  • Experience with automation and robotics
  • Experience in beamline controls using EPICS
  • Knowledge in engineering materials science
  • Knowledge in condensed matter physics
  • Experience with low temperature cryocoolers (below 80K)


  • Requires a PhD in physics, chemistry, computer science, materials science and related disciplines
  • At least 2 years of experience with independent scientific work after PhD
