ARI nARPES Beamline Scientist

Location: Upton

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 incorporates two end stations, one for ARPES and one for RIXS, and provides ultra-high spatial resolution (~100nm) scanning imaging capability in each end station via tightly-focusing mirror optics.

Other spectroscopic techniques are also provided including XPS, XAS, inverse XAS, photoelectron diffraction, and fluorescence. The ARI beamline is currently under construction with expected first light in the summer of 2026.

As the ARI Beamline Scientist concentrating on its nano-ARPES (nARPES) end station and scientific program, the successful candidate will work closely with a multidisciplinary team including beamline scientists, data analysis scientists, technicians, engineers, and other support staff to conduct the beamline operations and user program associated with the ARI nARPES end station. The ARI nARPES Beamline Scientist will conduct a forefront personal scientific program, advance the ARI nARPES science program, enhance ARI beamline capabilities in support of the nARPES program, and propose technical improvements and upgrades to ensure that the ARI nARPES end station remains at the state-of-the-art.

The successful candidate will also work closely with the ARI nano-RIXS (nRIXS) beamline scientist to conduct a joint scientific program that takes optimal advantage of the unique combination of nARPES and nRIXS capabilities applied to the same sample.

Essential Duties and Responsibilities:

* Refine and evolve the mission and technical scope of the ARI nARPES end station by interacting effectively with the scientific user community and with the Electronic Structure Techniques Program and NSLS-II colleagues

* Grow the ARI nARPES end station'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 end station, providing oversight of staff and users working at this end station

* Supervise scientific staff assigned to the ARI nARPES end station

* 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 end station equipment

* Contribute to the development and management of the nARPES end station's controls and data acquisition, management, and analysis

* Collaborate with NSLS-II staff, BNL scientists, and/or external researchers to develop an independent scientific and/or technical research and development program that leverages or enhances the unique capabilities of the ARI beamline and its ARPES end station

* Coordinate the ARI nARPES program with the ARI nRIXS program and with the programs of other NSLS-II beamlines within and outside the Electronic Structure Techniques Program that offer complementary techniques or capabilities

Position Requirements

Required Knowledge, Skills, and Abilities:

* PhD. in Physics, Chemistry, Materials Science, or other relevant fields with at least 2 years' experience in synchrotron-based research with 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

Preferred Knowledge, Skills, and Abilities:

* PhD. in Physics, Chemistry, Materials Science, or other relevant fields with at least 4 years' experience in synchrotron-based research with 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
