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, these facilities carry 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: http://neutrons.ornl.gov.

Major Duties/Responsibilities
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.

Qualifications Required
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).

Qualifications Desired
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
Ability to work with other technical and scientific support groups to advance sample environment, data reduction and data
analysis for neutron powder diffraction.

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.

This position will remain open for a minimum of 5 days after which it will close when a qualified candidate is identified and/or

We accept Word(.doc, .docx), Excel(.xls, .xlsx), PowerPoint(.ppt, .pptx), Adobe(.pdf), Rich Text Format(.rtf), HTML(.htm,
.hmtl) and text files(.txt) up to 2MB in size. Resumes from third party vendors will not be accepted; these resumes will be
deleted and the candidates submitted will not be considered for employment.

CFR 707.4 will be conducted by the employer and a background investigation by the Federal government may be required
to obtain an access authorization prior to employment and subsequent reinvestigations may be required.
If the position is covered by the Counterintelligence Evaluation Program regulations at 10 CFR 709, a counterintelligence
evaluation may include a counterintelligence-scope polygraph examination.

ORNL is an equal opportunity employer. All qualified applicants, including individuals with disabilities and protected
veterans, are encouraged to apply. UT-Battelle is an E-Verify Employer.
