ARI nARPES Beamline Scientist

Position Description

The National Synchrotron Light Source II (NSLS‑II) at Brookhaven National Laboratory seeks a Beamline Scientist for the soft X‑ray angle‑resolved photoemission spectroscopy (ARPES) and resonant inelastic X‑ray scattering (RIXS) Imaging (ARI) beamline. The ARI beamline has two endstations—one ARPES and one RIXS—each offering ~100nm spatial resolution through tightly‑focusing mirror optics and additional techniques such as XPS, XAS, inverse XAS, photoelectron diffraction, and fluorescence.

The beamline is under construction with first light anticipated in summer
2026. The successful candidate will focus on the nano‑ARPES (nARPES) endstation, conduct beamline operations, and lead the scientific program in collaboration with beamline scientists, technicians, engineers, and other support staff.

• Refine and evolve the mission and technical scope of the ARI nARPES endstation by engaging the scientific user community and NSLS‑II colleagues.
• Grow the ARI nARPES endstation’s scientific program in line with the NSLS‑II strategic plan and support the facility mission with a focus on scanning imaging angle‑resolved photoemission spectroscopy.
• Conduct safe operation of the ARI beamline and its nARPES endstation, overseeing staff and users.
• Supervise scientific staff assigned to the ARI nARPES endstation.
• Contribute to development and management of the ARI beamline operating budget, beam‑time allocation, and schedule.
• Contribute to the design, implementation, maintenance, and upgrade of ARI beamline and its nARPES endstation equipment.
• Contribute to the development and management of the nARPES endstation’s controls, data acquisition, management, and analysis.
• Collaborate with NSLS‑II staff, BNL scientists, and external researchers to develop an independent scientific or technical research and development program that leverages or enhances the unique capabilities of the ARI beamline and its ARPES endstation.
• Coordinate the ARI nARPES program with the ARI nRIXS program and with the programs of other NSLS‑II beamlines that offer complementary techniques or capabilities.

• PhD in Physics, Chemistry, Materials Science, or a relevant field with at least 2years’ experience in synchrotron‑based research, including significant experience using electron spectroscopy and/or X‑ray scattering techniques.
• Expert knowledge of ARPES fundamentals and data analysis.
• Strong publication record using ARPES techniques.
• Excellent written and communication skills.
• Ability to interact effectively in a team environment with a diverse group of scientists, engineers, technical staff, and users.

• PhD in Physics, Chemistry, Materials Science, or a relevant field with at least 4years’ experience in synchrotron‑based research, including significant experience using electron spectroscopy and/or X‑ray scattering techniques.
• Demonstrated success in the design, installation, and/or commissioning of a synchrotron radiation beamline.
• Working knowledge of soft X‑ray optics, X‑ray and electron detectors, and/or beamline control systems (e.g., EPICS).
• Recognized expertise in angle‑resolved photoemission spectroscopy.
• Programming skills for data analysis and/or collection in Python.

Salary range: $104,700 – $160,000 per year. Comprehensive benefits program is available. For more information, see Brookhaven National Laboratory benefits.
