We have an opening for a Materials Physics Academic Graduate Appointee to help develop systems to induce high dynamic pressures and improve the models used in hydrocode simulations. This position is in the Equation of State - Capability Development and Applications Group in the Physics Division.

Depending on your assignment, this position may offer a hybrid schedule, blending in-person and virtual presence. You may have the flexibility to work from home one or more days per week.

You will

• Work as a member of multidisciplinary teams, designing and interpreting experiments involving dynamic compression of matter to high pressures;
• Perform hydrocode simulations of the experiments and their applications;
• Contribute to the development of improved models used in the simulations, including of the equation of state and strength of component materials, shock-induced exothermic reactions, and the transport and deposition of laser energy;
• Analyze results and prepare technical reports and presentations as appropriate;
• Perform other duties as assigned.

• Bachelor's degree in physics, chemistry, engineering or similar numerate subject.
• Experience in performing multidimensional hydrocode simulations of impacts, detonation, and laser heating/ablation to be able to work effectively with infrequent supervision.
• Knowledge of fluid mechanics, continuum mechanics, shock physics, and thermodynamics.
• Knowledge of materials science and the properties of crystalline materials at elevated pressure, e.g. phase transitions.
• Practical knowledge of numerical methods for solving the hydrodynamic equations for applications involving shocks and their reflections, sufficient to be able to avoid common pitfalls.
• Experience participating in experimental science, interacting with experimental teams, and contributing to the preparation of manuscripts and proposals.
• Computer literacy, including office applications, data processing/programming, and preparation of graphs and technical materials.

Qualifications We Desire

• Knowledge of hydrodynamics, shock physics, reactive flow, and radiation transport.
• Knowledge of quantum mechanics and its application to the electronic structure of matter.
• Knowledge or experience relevant to drives and diagnostics for dynamic loading systems, e.g. HE detonation, radiation transport, high-power pulsed laser systems, x-ray diffraction, laser interferometry, radiography.
• Knowledge or experience of design engineering, i.e. optimizing a system to achieve a desired performance.
• Experience of a programming language such as Python.
• Ability to secure and maintain a U.S. DOE Q-level security clearance, which requires U.S. citizenship.
