Responsibilities : Group Overview :

Group Overview :

Our group performs system hardening technology research and development. We specialize in modeling the shock response of materials and structures to impulsive and thermal loadings.

This involves application of hydrocodes (e.g., WONDY and ALE3D) and finite element codes (e.g., ABAQUS) to impact and radiation driven problems.

Radiation transport codes such as MCNP and ITS are used to calculate thermal loadings. Modeling results are compared to experimental results from a variety of test facilities including :

• Light gas gun impact facility (Arcfield)
• Laser and pulsed power-driven Plasma Radiation Sources (PRS)

e.g. LLNL National Ignition Facility and Sandia Z Machine)

• Laser ablation driven shock facilities (e.g., LLNL NIF Direct Laser Impulse)
• Pulse power driven electron and proton beams (e.g., DTRA PITHON and NRL GAMBLE II) and
• Explosive loading facilities (e.g., Sandia Light Initiated High Explosives (LIHE))

Job Responsibilities :

Develop detailed test objectives from program requirements.

• Assist in development of testing approaches to meet objectives.
• Supervise the development, modification, and execution of detailed test plans.
• Assist in the development of new instrumentation and post-processing methodologies, including quantification of uncertainties.
• Perform scoping calculations using hydrocodes, radiation transport codes, or other tools to support test development.
• Perform sanity-checking calculations of test data to evaluate data quality.
• Develop proposals for obtaining access to NIF and other test facilities.
• Prepare technical reports and presentations that effectively communicate methods and results.
• Defend results at customer and peer review meetings.

• Experience with developing or performing experiments in physics, engineering, or related field
• Ability to obtain and maintain a Top Secret clearance

Desired Qualifications :

• A PhD in Physics, Mechanical Engineering, Aerospace Engineering, Civil Engineering, Applied Mechanics, Applied Physics, or related field
• Experience with fielding shock physics experiments
• Experience with determining experiment objectives from program requirements
• Experience with pulsed-power facilities (e.g., PITHON, GAMBLE, Z)
• Experience with laser matter interaction testing and / or analysis
• Experience with hydrocode / shock physics theory, simulations, and software
• Experience in radiation transport simulations and software
• Experience with programming languages such as Python, Fortran, or C++
• Demonstrated ability to meet milestones and deadlines
• Demonstrated ability to work independently as well as part of a team
• Demonstrated ability to prepare technical reports and presentations that effectively communicate methods and results
• Strong oral and written communication skills - particularly with respect to technical reports and presentations
