Beamline Scientist

Website BrookhavenLab NSLS-II (National Synchrotron Light Source)

Job ID 3503

Brookhaven National Laboratory ( delivers discovery science and transformative technology to power and secure the nation’s future. Brookhaven Lab is a multidisciplinary laboratory with seven Nobel Prize-winning discoveries, 37 R&D 100 Awards, and more than 70 years of pioneering research. The Lab is primarily supported by the U.S. Department of Energy’s (DOE) Office of Science. Brookhaven Science Associates (BSA) operates and manages the Laboratory for DOE. BSA is a partnership between Battelle and The Research Foundation for the State University of New York on behalf of Stony Brook University.

Organizational Overview

The National Synchrotron Light Source II (NSLS-II) is an advanced 3 GeV synchrotron light source operating at Brookhaven National Laboratory, a multipurpose research institution funded primarily by the U.S. Department of Energy’s Office of Science. NSLS-II seeks a motivated Beamline Scientist for the ARPES and RIXS Imaging (ARI) Beamline. The ARI Beamline, currently under construction and targeting first light in early 2027, provides state-of-the-art nano-imaging Resonant Inelastic X-rays Scattering (n-RIXS) and nano-imaging Angular Resolved Photoemission (n-ARPES) capabilities, with ultra-high spatial resolution (~ 100nm) over a wide photon energy range (40 eV – 1000 eV) and with ultra-high photon flux (>1×1012 ph/s),  enabling the study of the electronic, chemical, atomic and magnetic properties of materials with a spatial resolution on the same order as prospective devices and confinement induced quantum effects.

Position Description

The successful candidate will be part of a diverse scientific program. Working closely with the ARI Lead Beamline Scientist and the scientific user community, the selected candidate will assist with design, construction and commissioning of the beamline, support operation of the beamline, contribute to development/upgrade projects, establish relevant research projects, and develop opportunities for scientific collaborations that exploit the unique qualities of the ARI beamline.

Key Duties and Responsibilities:

  • Actively contribute to the beamline design, construction, operations, and user support.
  • Innovate and upgrade the instrumentation to fulfil scientific demands and maintain beamline performance at the forefront of the field.
  • Provide, as part of an open-source process, data acquisition and analysis software tools to enable staff and users at the ARI beamline to maintain scientific output at the forefront of the field.
  • Provide users with the support and capabilities needed to achieve and complete high-impact experiments.
  • Develop a science program, instrumentation and/or analysis software working as a member of a team to conduct experimental programs in the Soft X-ray Scattering and Spectroscopy Program at NSLS-II.
  • Collaborate with NSLS-II scientists, BNL scientists, and General Users for effective and innovative use of the ARI beamline.

Position Requirements

  • PhD in Physics, Chemistry, Materials Science or related fields.
  • At least two (2) years of experience (beyond the PhD) in synchrotron-based electron spectroscopy and/or scattering techniques.
  • Demonstrated experience with the RIXS technique.
  • Demonstrated experience involving multi-modal investigations using RIXS and other techniques; such as ARPES, XAS, X-ray Diffraction, etc.
  • Good understanding of experimental instrumentation.
  • Python programming experience, or similar skills, and a willingness to contribute to the development of NSLS-II data analysis tools in an open-source, collaborative environment.
  • Demonstrated publication record.
  • Demonstrated communication and interpersonal skills.
  • Ability to interact effectively in a team environment with a diverse group of scientists, engineers, technical staff, and users.

Preferred Knowledge, Skills, and Abilities:

  • Demonstrated Experience with the ARPES technique.
  • Demonstrated Experience involving multi-modal investigations using ARPES and other techniques; such as RIXS, XAS, X-ray Diffraction, etc.
  • Experience of constructing and/or operating beamlines and providing user support in an X-ray user facility.
  • Demonstrated experience in data analysis and data reduction, particularly from multiple different techniques, such as RIXS, ARPES, XAS, X-ray Diffraction, etc.
  • Demonstrated capability of working independently.
  • Good organizational, analytical skills and work planning capabilities.
  • Proven abilities for disseminating research by writing papers and giving scientific presentations.


  • The selected candidate will be placed at the appropriate professional level dependent upon depth and breadth of relevant knowledge and skills, as well as years of relevant experience.
