We have an opening in the Nuclear and Particle Physics Group for a Postdoctoral Researcher to play a major role in developing and conducting nuclear physics experiments to improve the gamma-ray spectroscopy data and yields for fission products that are of interest to stockpile stewardship, nuclear energy, and nuclear astrophysics. This research will make use of critical assemblies available in the NNSA Complex, nuclear reactors and mono-energetic neutron sources. You will set up experiments at these facilities, collect high resolution gamma-ray spectra and develop new analysis techniques to study the time dependent spectra in detail. You will lead the development of a new rabbit system and associated HPGe detector array to take data at very short times following a neutron irradiation of actinide materials. This position is in the Nuclear and Particle Physics Group in the Nuclear and Chemical Sciences Division.
In this role you will
Conduct neutron irradiations of actinide materials at critical assemblies, nuclear reactors and/or mono-energetic neutron beam facilities
Lead development of rapid rabbit sample changer for short duration exposures of actinide materials to neutron fields and field experiments using the newly developed system
Publish research results in peer-reviewed scientific or technical journals and present results at external conferences, seminars, and/or technical meetings
Work in close collaboration with colleagues at LANL, PNNL and MSTS and other institutions to perform measurements of fission products
Provide technical contributions to the development of future nuclear physics experiments
Perform other duties as assigned.
PhD in a nuclear physics, nuclear astrophysics or related field
Advanced knowledge with accelerator-based nuclear physics experiments or neutron irradiations as well as gamma-ray spectroscopy
Experience with charged-particle and gamma ray detectors and radiation counting and their associated data analysis
Programming experience in C/C++, QT and other programming languages
Experience performing analysis using ROOT
Documented publication record in peer-reviewed literature in physics or a related field.
Experience working collaboratively as part of a focused team
Proficient verbal and written communication skills to collaborate effectively in a multi-disciplinary team environment and present and explain technical information.

About Lawrence Livermore National Laboratory
For more than 60 years, the Lawrence Livermore National Laboratory has applied science and technology to make the world a safer place.Livermore’s defining responsibility is ensuring the safety, security and reliability of the nation’s nuclear deterrent. Yet LLNL’s mission is broader than stockpile stewardship, as dangers ranging from nuclear proliferation and terrorism to energy shortages and climate change threaten national security and global stability. The Laboratory’s science and engineering are being applied to achieve breakthroughs for counterterrorism and nonproliferation, defense and intelligence, energy and environmental security.
