Beamline Postdoctoral Research Associate / NB50542449
End Posting Date
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. To learn more about Neutron
Sciences at ORNL go to: http://neutrons.ornl.gov.
The Quantum Condensed Matter Division (QCMD) https://neutrons.ornl.gov/qcmd in the NScD at ORNL operates 13
instruments for elastic and inelastic neutron scattering studies of materials including the Magnetism Reflectometer.
Instruments are located at both HFIR and SNS. QCMD conducts research on materials with emergent properties that are
manifestly quantum in origin. Some examples of current interest include superconductivity, multiferroicity, low dimensional
and frustrated magnetism, orbital fluctuations, quantum criticality, nanocomposite and mesoscale magnetic materials.
The Magnetism Reflectometer located at the SNS is a vertical-surface polarized reflectometer optimized for the study of
magnetism nanoscale systems. The instrument provides a polarized beam with optional polarization analysis in order to
extract the structural and vector magnetic profile from thin films and nanostructure systems. A versatile array of sample
environment, capable of varying temperature, pressure, optical illumination, magnetic and electric fields, enables studies of
sample conditions relevant to quantum condensed matter. A reflectometer optimized for the study of magnetic nanostructures
is also under consideration as an instrument at the proposed SNS Second Target Station (STS).
The successful candidate will conduct scientific research, engage in beamline operations at the Magnetism Reflectometer,
and be an active participant in developing the design of the proposed STS reflectometer. Full training will be given in all
aspects of neutron reflectometry including beamline operation, data collection, processing and modeling.
Conduct research on a mutually agreed topic in magnetic thin films and nano-structures using the Magnetism Reflectometer
and other instruments as appropriate and to publish scientific papers resulting from this research and present results at
appropriate national and international meetings.
* Participate in operations of the Magnetism Reflectometer and provide beam line support to a limited number of users.
* The successful candidate will be part of the Thin Films and Nanostructures group in the Quantum Condensed Matter
Division at ORNL and will be expected to take part in all group activities, which include seminars and monthly meetings.
* The successful candidate will also be part of a growing team of instrument scientists and specialists developing conceptual
designs for STS instruments and will contribute to development of the design of a new reflectometer for the Second Target
* Ensure compliance with environment, safety, health and quality program requirements.
* Maintain 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, extensive work at chemical laboratories, and possible exposure to ionizing radiation normally associated with operation
of neutron scattering instruments for scientific research.
Applicants must hold a Ph.D. in physics, chemistry, chemical engineering, materials science or a related discipline from an
accredited institution. Candidates must be self-motivated and have good interpersonal, communication and presentational
skills. The date of application must be within 5 years of the most recent degree, and all degree requirements must be
complete before starting the appointment. Certain exceptions may be considered. This position is a temporary, full-time
assignment of 24 months.
Previous experience with neutron or x-ray reflectometry is desirable as well as experience gained in conducting experiments
at national user facilities. A familiarity with sample synthesis, deposition, and bench-top characterization is highly desirable.
Work Directions and Interfaces
Reports to Timothy Charlton. Will interface with the MR instrument team, SNS support staff, users of the MR, and with
members of the STS instrument design team.
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.
