The Advanced Photon Source is seeking a self-motivated experimentalist to support research and operations at several spectroscopy beamlines. This position will focus specifically on the new Sector 25 canted ID beamlines, which feature an X-ray microprobe station for fluorescence mapping, micro-spectroscopy, and confocal imaging, as well as advanced spectroscopy stations for high resolution fluorescence spectroscopy, emission spectroscopy using bent crystal analyzers and miniature X-ray spectrometers, and X-ray Raman spectroscopy. The SPC beamlines support research programs in environmental, biological, chemistry, catalysis, and energy science, and are operated in partnership with the Canadian Light Source.

As a beamline scientist, the selected candidate will work closely with the SPC group, support general users, and conduct a collaborative and independent science program. The SPC group has a strong collaborative team environment with opportunities to learn from and teach others within the group. The ideal candidate will have a strong background in physics and detailed knowledge of confocal X-ray microscopy and X-ray excited optical luminescence experiments.

Essential Duties and Responsibilities:

• Support and maintain the SPC X-ray beamline components, including experimental setups such as motorized components, Kirkpatrick-Baez (KB) focusing mirror systems, low and high temperature apparatus, energy dispersive detectors, and computer control.
• Initiate and participate in research activities, including new X-ray measurements and analysis to advance Spectroscopy at the APS.
• Interact with users to conduct spectroscopy experiments using X-ray techniques, including XEOL and confocal X-ray microscopy.
• Perform experimental data treatment and processing as part of independent research and user support.
• Advance the spectroscopy user program at the APS.
• Ensure compliance with safety regulations for the SPC beamlines.

Position Requirements

• Demonstrate strong analytical and problem-solving skills.

• Demonstrated publication record using synchrotron X-ray spectroscopy.
• Experience in X-ray spectroscopy and related data analysis and modeling.
• Excellent written and oral communication skills.
• Demonstrated experience in a team environment with a diverse group of scientists, engineers, technical staff, and users.
• At least six years of experience conducting independent experimental research at synchrotron facilities.
• Experience in managing and directing projects, as demonstrated by roles such as project lead, program manager, or review committee member.
• Strong problem solving, analytical, communication and time management skills.
• Familiarity with safety regulations in the context of synchrotron facilities.

• Ability to model Argonne’s core values of impact, safety, respect, integrity, and teamwork.

• Ability to understand, value, and promote diversity, equity, inclusion, and accessibility.

• Bachelors and 12+ years’ experience, Masters and 7+ years’ experience, PhD and 6+ years’ experience, or equivalent

Preferred Knowledge, Skills, and Experience:
• Ph.D. in experimental physics with a strong background in X-ray optics.

• Evidence of contribution to the larger scientific community such as membership or participation in professional organizations related to physics or spectroscopy, such as the American Society of Plant Biologists (ASPB), American Geological Union (AGU), and American Metrology Society (AMS).
• Development of synchrotron beamline instrumentation.
• Experience conducting in-situ synchrotron measurements under different sample environments.
• Ability to train others.
