Requisition Id 5988 Overview: 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 with particular emphasis on sensitivity and specificity in actual field operations, including use of radiation transport codes to model these systems and analysis codes to isolate signals of interest. The function of this position is to assist the group to perform the needed research and development that will yield novel and advanced detector systems, instrumentation, measurement techniques, and algorithms in support of applications from a broad user base. 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. Particular emphasis will be placed on development of fast-neutron and high energy x-ray imaging techniques. 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 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 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,
* Understanding of analytical techniques and modern data science and machine learning approaches,
* Proficiency with data analysis using ROOT and/or Python,
* Experience with modeling and simulation with MCNP or GEANT,
* An awareness of the mission space and for which applied radiation detection can contribute, including arms control, emergency response, and safeguards, and the current state of the art of these areas,
* Excellent human relation and oral and written communication skills, and
* Demonstrated initiative and ability to work as part of a team with a broad range of domestic or international collaborators.
* 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 Secret Compartmented Information (SCI) 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. In addition, due the SCI, you may also be subject to random polygraph testing. 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. We accept Word (.doc, .docx), Adobe (unsecured .pdf), Rich Text Format (.rtf), and HTML (.htm, .html) up to 5MB 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.
