Scientific Associate - Polarization

Date: Jan 10, 2023

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 9823 


The Neutron Optics and Polarization Group within the Neutron Technologies Division at Oak Ridge National Laboratory (ORNL) is looking for a Scientific Associate to provide technical and operations support for the group.  The mission of this group is to design new instruments, to develop new instrumental capabilities, and to support the day-to-day operation of our instruments with state-of-the-art technologies in the areas of neutron polarization, polarization analysis, and neutron optics.  Our research interests fall into these areas: developing new neutron polarization techniques, Larmor labeling methods, developing new instrument concepts, and neutron optics.  The group operates two development instruments at the High Flux Isotope Reactor (HFIR), as well as a set of development laboratories.  The group also supports usage of these techniques at both of our national user facilities, HFIR and the Spallation Neutron Source (SNS). 


As a Scientific Associate, you will join a team of R&D scientists and students who develop new devices and techniques for manipulating neutron beams and their polarization state.  You will assist with design, testing and operation of polarized neutron apparatus, and in particular operation of 3He-filter based neutron polarizers.  Interfacing with other teams, you will work with neutron instrument scientists and engineers who will lean on your expertise in finding solutions for their scientific, engineering, or technical requirements. 


Major Duties/Responsibilities:   

  • Support the development and routine operation of polarization devices, including 3He polarization filters 

  • Assist in the development of new polarized neutron techniques for neutron instruments at HFIR and SNS 

  • Support scientific research with neutron optics 

  • Participate in the operation of the neutron optics test beam lines at HFIR 

  • Assist internal and external scientists with neutron scattering experiments 

  • Maintain a strong commitment to the implementation and perpetuation of laboratory values and ethics. 

  • Ensure and monitor compliance with environment, safety, health (ESH), and quality program (QA) requirements 

  • Promptly identify ESH and QA issues and communicate them to project and division management, ESH and QA contacts, and/or subcontractor contacts as appropriate 

  • As a member of the ORNL scientific community, you will be expected to commit to ORNL's Research Code of Conduct.  Our full code of conduct, and a statement by the Lab Director's office can be found here:  


Basic Qualifications: 

  • A B.S. degree in engineering, physics, chemistry, materials science, or a closely related discipline 

  • A mimimum of 2 years of relevant experience 

  • Experience in some of these areas: mechanical assembly, basic cryogenic technology, computer automated design, operation of high-power lasers, modeling of magnetic fields 


Preferred Qualifications: 

  • A Master’s degree in engineering, physics, chemistry, materials science, or a closely related discipline 


Visa sponsorship is not available for this position.  


About Neutron Sciences Directorate: 
The Neutron Sciences Directorate (NScD) at Oak Ridge National Laboratory (ORNL) operates the High Flux Isotope Reactor (HFIR), the United States’ highest flux reactor-based neutron source, and the Spallation Neutron Source (SNS), the world’s most intense pulsed accelerator-based neutron source.  Together these facilities operate 30 instruments for neutron scattering research, each year carrying out in excess of 1,000 experiments in the physical, chemical, materials, biological and medical sciences for more than 3,000 visiting scientists.  HFIR also provides unique facilities for isotope production and neutron irradiation.  To learn more about Neutron Sciences at ORNL go to
