Title of Position:    Physicist

CNL's Applied Physics Branch explores and investigates the development and applications of radiation based systems and detectors, including performing experiments, developing physics models and simulations, and building, testing, and evaluating prototypes or third-party devices.

Within the area of Safety and Security, Applied Physics Branch pursues expertise to maintain CNL's position in: nuclear instrumentation (detector design, development, and testing), electronics expertise, optics, simulations and modelling (e.g., GEANT4 simulation of novel detectors or systems), algorithm development, data analysis, and system/equipment testing.

Job Duties:

The Applied Physicist will report to the Simulations & Measurements for Advanced Radiation Technologies (SMART) Section Head, and have the following responsibilities:

  • Contribute to the physics program in support of CNL's growth areas of nuclear safety and security, including Special Nuclear Material (SNM) detection, nuclear forensics, and reactor physics.
  • Develop improved modeling methods for SNM detection, nuclear forensics, or radiation detector technologies.
  • Capable of providing support and services in nuclear instrumentation and Monte-Carlo simulations relevant to radiation transport, such as GEANT4, MCNP, GARFIELD++.
  • Play a role in working on proposals and projects that address Federal S&T, and other customers, needs in areas related to applied physics.
  • Participate in international collaborative research.
  • Checks simulation predictions against experimental data from sophisticated experimental techniques for correctness.
  • Suggests new or refined experiments to answer key questions pertinent to models.
  • Assists in the assurance of safe and efficient operation through mathematical models.
  • May guide the work of junior scientists/engineers/technologists assigned to a common project, but usually not a continuing responsibility.
  • Analyzes and solves technical problems, makes independent studies/analysis/interpretations and conclusions, provides sound recommendations in their field.
  • Can articulate ideas and proposals for new projects and ongoing work. Gives presentations to customers, stakeholders, and conferences (international and domestic), and contributes to technical journals.
