NIF Radiochemistry - Postdoctoral Researcher

Join us and make YOUR mark on the World!

Are you interested in joining some of the brightest talent in the world to strengthen the United States’ security? Come join Lawrence Livermore National Laboratory (LLNL) where our employees apply their expertise to create solutions for BIG ideas that make our world a better place.

We are committed to a diverse and equitable workforce with an inclusive culture that values and celebrates the diversity of our people, talents, ideas, experiences, and perspectives. This is essential to innovation and creativity for continued success of the Laboratory’s mission.

We have an opening for a Postdoctoral Researcher to play a major role in development of novel radiochemical separation and delivery techniques at the micro scale for production of targets for high energy density programs. This position is in the Nuclear and Radiochemistry group of the Nuclear and Chemical Sciences Division.

In this role you will 

• Develop delivery systems (injection and vacuum assisted) for adding microliters of radionuclides into ignition capsules for high energy density experiments.
• Perform sample and data analysis and interpret results.
• Develop experimental methods, separation techniques, and analysis approaches needed to collect and isolate radioactive isotopes produced at accelerator facilities.
• Prepare and conduct technical presentations for internal and external audiences.
• Document research, publish papers in peer-reviewed journals, and present results within the DOE community and at conferences.
• Pursue independent (but complementary) research interests and interact with a broad spectrum of scientists internally and externally.
• Collaborate with others in a multidisciplinary team environment to accomplish research goals.
• Perform other duties as assigned.

• Ability to maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship.
• PhD in nuclear chemistry, nuclear physics, nuclear engineering, radiochemistry, chemical engineering, or related field.
• Experience with laboratory instrumentation and associated software controls and designing, assembling, and running nuclear science experiments based on radiochemical or nuclear chemistry methods.
• Experience with charged-particle and gamma-ray detectors and radiation counting and their associated data analyses.
• Ability to safely work with radioactive materials (> 1 microCurie).
• Ability to develop experimental methods, separation techniques, and analysis approaches needed to collect and isolate radioactive isotopes produced at accelerator facilities.
• Experience with radionuclide separation methods, such as liquid-liquid extraction, ion exchange chromatography or solvent extraction.
• Experience in experimental nuclear science to help solve a variety of programmatic challenges in national security, with experience in data analysis and interpretation.
• Proficient verbal and written communication skills to collaborate effectively in a multi-disciplinary team environment and present and explain technical information.

Qualifications We Desire

• Experience with vacuum and cryogenic systems and techniques.
• Experience working on high energy density experimental facilities, such as short pulse laser systems.
