Applied Physicist

CNL’s Applied Physics Branch undertakes simulations and modelling, experimental measurements, operational support, and novel technology development, in program areas primarily related to Safety and Security. Safety and Security in this context means the monitoring, detection, enforcement and policies to protect Canadians and Canada’s borders and Canada’s participation in international activities. While this often fall under Nuclear Safety & Security, the application of nuclear methods and tools and related technologies applied to aspects of the safety & security of Canadians is also pursued.

The Simulations & Measurements for Advanced Radiation Technologies (SMART) section pursues activities pertaining to the interaction of radiation with matter, including detection of special nuclear materials (SNM), model development, simulations, and experiments. Currently, this includes, but is not limited to, the development, improvement and validation of muon tomography detectors and algorithms for the detection of shielded special nuclear materials, exploration of using disruptive liquid argon technology for screening cargo containers at the borders, and evaluation of multi-mode scintillators for localization and identification of radioactive sources. The work supports CNL's activities mainly in Safety and Security but also Energy, Health and Environment, supporting Federal agencies and other external customers. Tasks are multi-disciplinary and include interfacing with staff from other areas of the organisation.

The successful applicant will have the following responsibilities:
• Contribute to the physics program in areas of nuclear safety and security, including SNM detection, nuclear forensics, radiation interactions in matter, and reactor physics;
• Provide support and services in nuclear instrumentation and Monte-Carlo simulations relevant to radiation transport (Geant4, MCNP);
• Play a role in working on proposals and projects that address internal and external customer needs in areas related to applied physics;
• Check simulation predictions against experimental data from sophisticated experimental and theoretical techniques;
• Suggest new or refined experiments to answer key questions pertinent to models;
• May guide the work of students, technologists and more junior scientists/engineers assigned to a common project;
• Analyze and solve technical problems, make independent studies/analysis/interpretations and conclusions, provides sound recommendations;
• Contribute to R&D planning, in particular to provide technical review and definition of work scope;
• Provide progress reports to the Section Head/Manager/Lead, against deliverables for R&D or commercial projects;
• Can articulate ideas and proposals for new projects and ongoing work.
• Give presentations to customers, stakeholders, and conferences (international and domestic), and contribute to technical journals;
• Participate in training courses and seek opportunities for technical training;
• Other duties as assigned by line management.

• B.Sc., M.Sc. or Ph.D. in physics, engineering physics, nuclear engineering or related field from a university of recognized standing.

Candidates should have demonstrated experience and skills in the following:
• Knowledge of nuclear/particle physics and a strong computing background with a working knowledge of at least C/C++ with ROOT or Python with SciPy/NumPy, and UNIX/Linux operating systems.
• Experience with computer programming for the purpose of acquiring and analyzing data and for comparison with model predictions.
• Experience with Monte Carlo simulations (Geant4/MCNP or similar) for developing models of radiation detectors.
• Experience with advanced data analytics, such as machine learning techniques and/or artificial intelligence (AI), would be considered an asset.
• Experience handling and operating radiation detectors.
• Experience with detector hardware and electronics, such as configuring VME, CAMAC, and/or NIM data acquisition systems, FPGA programming would be considered an asset.
• Good computer skills, including word processing, spreadsheets.
• Ability to perform work carefully and accurately, with good knowledge of and commitment to quality assurance.
• Good analytical, documentation and communication skills.
• Leadership experience, in any environment, would be an asset.
• Experience with the development of novel detection techniques for nuclear safety and security, e.g., Muon Tomography, would be an asset.
Preference will be given to candidates with experience in detector development and experimental physics measurements.
