Oak Ridge, USA
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.

The Chemical and Engineering Materials Division (CEMD) of the NScD at Oak Ridge National Laboratory is seeking a highly motivated Instrument Scientist for the POWGEN diffractometer at the SNS.
The Instrument Scientist will report to the Chemical Crystallography Group Leader in CEMD, and will participate in research activities using POWGEN across a diverse range of fields such as but not limited to: physics, in particular magnetic materials; chemistry; materials science; and mineralogy and earth/planetary science using powder diffraction experimental and analysis techniques. This will involve safe operation and user support for the beamline, which includes user assistance as local contact, helping with experimental setup, data acquisition and data analysis. The incumbent will champion developments in instrumentation, sample environment, and software to help maintain and further develop the performance of POWGEN and expand its user base. The candidate is also expected to develop a high-quality personal research program using neutron powder diffraction, publish research results in scientific journals, maintain a strong commitment to the implementation and perpetuation of values and ethics, and ensure compliance with environmental, safety, health and quality program
requirements. This position supports programs and facilities at SNS that are operational 24 hours a day and seven days a week. This position will require flexibility in work schedule, and support will be needed during off duty hours and weekends, in many cases, to assist with user experiments.
Work Directions and Interfaces:
This position will report to the Chemical Crystallography Group Leader. Candidate will work closely with research staff in CEMD and programmers in the Neutron Data Analysis and Visualization Division and other support groups. The individual will be expected to collaborate with science programs across other directorates within ORNL and with external user groups.
Candidates with Ph.D. and two plus years of post-doctoral experience in Chemistry, Materials Science, Physics, or related fields will be considered. Experience in neutron and/or x-ray powder diffraction instrumentation is required. The candidate should be self-motivated, have strong written and oral communication skills, and the ability to work within a multi-disciplinary team environment on scientifically challenging problems. A strong record of publication in peer-reviewed scientific journals is required. Ability to develop an independent science program using the above techniques is also required (a research plan should be supplied to demonstrate this).
Previous beamline support experience in a neutron or synchrotron x-ray central facility.
Experience with magnetic Rietveld analysis/programming is highly desirable.
Ability to work with graduate students, post-doctoral researchers, and other research scientists from both academia and industry.
Ability to work with other technical and scientific support groups to advance sample environment, data reduction and data analysis for neutron powder diffraction.
