Modeling and Simulation of Inertial Confinement Fusion Physics Postdoc

What You Will Do

The Eulerian Codes Group (XCP-2) in the X-Computational Physics (XCP) Division is seeking an outstanding candidate for a postdoctoral position in code development and modeling related to plasma physics and Inertial Confinement Fusion (ICF). This work will involve contributing to the development of one or more physics packages relevant to inertial confinement fusion (ICF) modeling as well as utilizing novel capabilities to simulate ICF implosions. XCP-2 supports and develops the xRAGE Radiation-Hydrodynamics Eulerian Adaptive Mesh Refinement (AMR) code, which is widely used to perform simulations of ICF and High Energy Density Physics (HEDP) experiments. The candidate will assist in the development of plasma physics models in the xRAGE code. Specific models may include charged particle transport (for thermonuclear reaction products), thermal conduction (non-local and coupling to laser physics and magnetohydrodynamics/MHD), non-local thermodynamic equilibrium (nLTE) and/or plasma transport. The position will also involve validation of physics models and their implementation in the xRAGE code as applied to the simulation of ICF and HEDP experiments, as well as performing detailed code comparisons. The successful candidate is expected to work in a team environment with experimentalists and computational scientists, implement models and methods in xRAGE, and publish results.

Additional Details

Directive 206.2 - Employment with Triad requires a favorable decision by NNSA indicating employee is suitable under NNSA Supplemental Directive 206.2. Please note that this requirement applies only to citizens of the United States. Foreign nationals are subject to a similar requirement under DOE Order 142.3A.

Q Clearance: Selected applicants will be subject to a background investigation conducted by or on behalf of the Federal Government, and must meet eligibility requirements* for access to classified matter. This position requires a Q clearance. and obtaining such clearance requires US Citizenship except in extremely rare circumstances. Dependent upon the position, additional authorization to access classified information may be required, which may or may not be available to dual citizens. Receipt of a Q clearance and additional access authorization ultimately is a decision of the Federal Government and not of Triad.

*Eligibility requirements: To obtain a clearance, an individual must be at least 18 years of age; U.S. citizenship is required except in very limited circumstances. See DOE Order 472.2 for additional information.

New-Employment Drug Test: The Laboratory requires successful applicants to complete a new-employment drug test and maintains a substance abuse policy that includes random drug testing. Although New Mexico and other states have legalized the use of marijuana, use and possession of marijuana remain illegal under federal law. A positive drug test for marijuana will result in termination of employment, even if the use was pre-offer.

Equal Opportunity: Los Alamos National Laboratory is an equal opportunity employer and supports a diverse and inclusive workforce. All employment practices are based on qualification and merit, without regard to race, color, national origin, ancestry, religion, age, sex, gender identity, sexual orientation or preference, marital status or spousal affiliation, physical or mental disability, medical conditions, pregnancy, status as a protected veteran, genetic information, or citizenship within the limits imposed by federal laws and regulations.
