Physicist/Nuclear Engineer - R&D Associate

Date: Sep 15, 2021

Location: Oak Ridge, TN, US, 37830-8050

Company: Oak Ridge National Laboratory

Requisition Id 6565 


We are seeking a Physicist/Nuclear Engineer who will focus on novel and advanced detector systems, instrumentation, measurement techniques, and algorithms in support of applications from a broad user base. This position resides in the Advanced Radiation Detection, imaging, Data Science, and Applications group in the Nuclear Science & Advanced Technology section of the Physics Division in the Physical Sciences Directorate at Oak Ridge National Laboratory (ORNL).  


The Advanced Radiation Detection, Imaging, Data Science, and Applications (ARDIDSA) group focuses on the development and evaluation of novel and advanced radiation detector and non-destructive evaluation concepts for basic science, nonproliferation, national security, and intelligence organizations. The ARDIDSA group performs the research and technology development to evolve these advanced concepts from conception to demonstration or deployment.  The function of this position is to support the group’s research and development goals by developing asynchronous, high-rate data acquisition software and/or firmware to support development of the next generation of detectors or systems.


The successful candidate will work with research staff within ARDIDSA to develop and apply radiation detection, imaging, and data-science technologies to a wide variety of subjects including nuclear material detection, nuclide identification, and radioactive materials localization capabilities to support nuclear security missions. The candidate will work as part of a team to meet deliverables and address technology or system issues. Results will be documented by publication in high impact papers, journals, conference papers and technical reports. The work will involve collaboration in a team environment to develop and present research proposals to generate new funding.



Major Duties/Responsibilities: 

  • Development of high-rate data acquisition software and/or firmware to support next generation novel radiation detector sensors and systems
  • Development of physics based algorithms for advanced radiation detection systems
  • Use of model and simulation tools to guide experimental system development and validate experimental results


Basic Qualifications:

  • A PhD in physics, nuclear engineering, or a related discipline
  • Experience in advanced radiation detection and related analysis
  • Demonstrated experience writing and qualifying software for high rate, asynchronous data acquisition to support nuclear detection, characterization, or imaging systems


Preferred Qualifications:

  • Demonstrated hands-on experience in experimental laboratory techniques, including the development of advanced and/or novel detectors, component-level familiarity with simple circuits using breadboards and/or printed circuit boards, and experience with silicon PM light sensors and PSD-plastic scintillators,
  • Proficiency with data analysis using ROOT and/or Python,
  • Experience with radiation transport simulation using MCNP or GEANT, including modeling of detector response,
  • Excellent human relation and oral and written communication skills,
  • Demonstrated initiative and ability to work as part of a team with a broad range of domestic or international collaborators, and
  • Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs


Special Requirements

This position requires the ability to obtain and maintain a Q clearance from the Department of Energy. As such, this position is a Workplace Substance Abuse (WSAP) testing designated position. WSAP positions require passing a pre-placement drug test and participation in an ongoing random drug testing program.


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