The Advanced Photon Source (APS) POLAR beamline is building a new instrument, named MagXES, that leverages the polarization dependence of the x-ray emission process to increase the sensitivity of magnetism-dependent x-ray measurements. This instrument will take advantage of the sub-micrometer beam size, advanced x-ray polarization control, high magnetic field, low temperature, and high-pressure capabilities of the new POLAR beamline. MagXES will, therefore, enable high-throughput element-resolved measurements of magnetism and electronic properties at extreme conditions.

The Magnetic Materials group in the X-ray Science Division seeks a Postdoctoral Appointee to contribute to the technical and scientific development of the MagXES spectrometer. The successful candidate will contribute to the spectrometer design and installation, as well as to the development of x-ray analyzers. Focus is expected to be placed on enabling high-pressure experiments, particularly using nanofabrication methods to tailor the high-pressure environment. Experiments will center on strongly correlated and topological systems using the MagXES as well as other x-ray spectroscopy and scattering probes.

Time Type

As an equal employment opportunity and affirmative action employer, and in accordance with our core values of impact, safety, respect, integrity and teamwork, Argonne National Laboratory is committed to a diverse and inclusive workplace that fosters collaborative scientific discovery and innovation. In support of this commitment, Argonne encourages minorities, women, veterans and individuals with disabilities to apply for employment. Argonne considers all qualified applicants for employment without regard to age, ancestry, citizenship status, color, disability, gender, gender identity, gender expression, genetic information, marital status, national origin, pregnancy, race, religion, sexual orientation, veteran status or any other characteristic protected by law.

Argonne employees, and certain guest researchers and contractors, are subject to particular restrictions related to participation in Foreign Government Sponsored or Affiliated Activities, as defined and detailed in United States Department of Energy Order 486.1A. You will be asked to disclose any such participation in the application phase for review by Argonne's Legal Department.  

All Argonne offers of employment are contingent upon a background check that includes an assessment of criminal conviction history conducted on an individualized and case-by-case basis.  Please be advised that Argonne positions require upon hire (or may require in the future) for the individual be to obtain a government access authorization that involves additional background check requirements.  Failure to obtain or maintain such government access authorization could result in the withdrawal of a job offer or future termination of employment.
