Description of Institution

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. HFIR also provides unique facilities for isotope production and neutron irradiation.

Job description

The Advance Diffraction Group in the Chemical and Engineering Materials Division (CEMD) of the NcSD operates powder diffraction instruments addressing a range of problems in chemistry and materials research. Areas of research supported by the group include the structure and behavior of electrical energy storage materials and systems, fundamentals of structure under pressure and/or temperature conditions, and the effects of processing conditions on material performance.

The Advance Diffraction Group in CEMD has an immediate opening for two postdoctoral positions focused on the study of disordered materials and developing total scattering techniques. The primary responsibilities of the candidates will be to develop and use new software tools to reduce and analysis total scattering data, primarily at the high-flux neutron total scattering instrument NOMAD. The first role will aim at streamlining the data reduction process within the Mantid software framework to reduce the time from experiment to data analysis. The second role will continue the development of the
RMCP analysis package and develop other data analysis tools. In both cases the aim is to have science driven software solutions, so the roles will interact closely with each other and other projects in the group and involve a combination of hands-on experimentation and programming. Laboratory characterization and complementary scattering techniques (including electron microscopy, synchrotron x-ray total scattering, XFAS, etc.) may also be pursued. The positions will allow the postdoctoral scientists to develop expertise, broaden experience and to interact with a diverse set of scientists working and visiting ORNL’s neutron facilities.

Major Duties/Responsibilities:

  • Develop, implement and utilize novel data reduction and data modeling algorithms for neutron total scattering and
    supporting techniques.
  • Employ experiments to study and understand the links between nano-structural details and materials properties utilizing
    neutron total scattering and supporting techniques.
  • Publish scientific papers resulting from this research and present results at appropriate national and international meetings.
  • Ensure compliance with environment, safety, health and quality program requirements.
  • Maintain a strong commitment to the implementation and perpetuation of values and ethics.
  • Physical requirements for this job include the use of hand and eye protection gear, kneeling, sitting for extended periods of
    time, working with sample environment equipment, and possible exposure to ionization radiation normally associated with
    operation of neutron scattering instruments for scientific research.

The appointment length will be up to 24 months with the potential for extension. Initial appointments and extensions are subject to performance and availability of funding.

Requested Profile

Qualifications Required:
A Ph.D. in Materials Science, Chemistry, Physics, or other related science field is required. Applicants must have received their PhD within five years of this application and must complete all degree requirements before starting their appointment. Candidates should be self-motivated, have good interpersonal, communication and presentation skills and a demonstrated ability to interact effectively with colleagues at all levels. The ability to work as a member of a multi-disciplinary team is a critical asset.
Employment is contingent upon the results of a pre-employment drug screen which must be administered and cleared before
employment can begin.

Qualifications Desired:
Previous experience in neutron and/or X-ray scattering applied to nanostructure and/or disordered crystalline studies is desired. Candidates with total scattering (local structure) expertise and data modeling programs are highly encouraged to apply. Programming proficiency in Python, C++, and/or Fortran is desired.
