Postdoctoral Research Associate -
Instrument Development Group
Oak Ridge National Laboratory
Oak Ridge, TN
Project Description:
The Neutron Facilities Development Division (NFDD) at Oak Ridge National Laboratory (ORNL) invites applications for a position as Neutron Scattering Instrument Development Associate in the Instrument Development Group. The successful candidate will be tasked with developing and implementing a robust portable MISANS component that can be deployed on various neutron scattering instrument beamlines to provide new capability. Modulated-intensity small angle neutron scattering, or MISANS, instrument uses the modulated intensity with zero effort (MIEZE) technique, a variant of the neutron resonance spin-echo. The adaptation of this method to a small angle neutron scattering provides the possibility of studying slow dynamics with energy changes in the neV-range. The advantage of the MIEZE technique over other spin-echo techniques is that all of the polarizing neutron optics can be installed upstream of the sample, so that in principle the signal is not subject to depolarization at the sample position.
The NFDD is responsible for developing neutron scattering instruments located at both the Spallation Neutron Source (SNS) and the High Flux Isotope Reactor (HFIR). Research at the facilities encompasses the physical, chemical, biological, medical and materials sciences.
Major Duties/Responsibilities:
* Works with and provides technical guidance to Instrument Scientists in the proper use of the beamline components developed.
* Serves as the technical specialist for the operation and maintenance of sophisticated equipment used for neutron scattering.
* Plans and leads in the testing and evaluation of new or developmental equipment.
* Ensures that beam line operations are performed under safe and environmentally sound conditions.
* Proposes, develops, and presents procedures for operating and maintaining beamline equipment.
* May give work direction to technicians, craft workers, and less experienced personnel.
A PhD degree in a physical science, engineering or related field is required. Good communications and interpersonal skills is required. Ability to work in a team environment is required. Demonstrated computer literacy including proficiency in word processing required. Direct experience working on neutron scattering related instruments or radio frequency devices is highly desirable. The applicant must be capable of working with scientists and engineers from verbal or written instructions. Periods of moderate travel and off-normal work hours will be required. Applicants cannot have received the most recent degree more than five years prior to the date of application and must complete all degree requirements before starting their appointment. Applications will be accepted until the position is filled.
Technical Questions:
Questions regarding the position can be directed to Dr. Lee Robertson (robertsonjl at ornl.gov) or Dr. Lowell Crow (crowmljr at ornl.gov). Please include the requisition number and title when corresponding.
How to Apply:
Qualified applicants must apply online at https://www2.orau.gov/ORNL_POST/. All applicants will need to register before they can begin the online application. For complete instructions, on how to apply, please see the instructions at http://www.orau.gov/orise/edu/ornl/ornl-pdpm/application.htm.
This appointment is offered through the ORNL Postgraduate Research Participation Program and is administered by the Oak Ridge Institute for Science and Education (ORISE). The program is open to all qualified U.S. and non-U.S. citizens without regard to race, color, age, religion, sex, national origin, physical or mental disability, or status as a Vietnam-era veteran or disabled veteran
