Join us and make YOUR mark on the World!

Come join Lawrence Livermore National Laboratory (LLNL) where we apply science and technology to make the world a safer place; now one of 2020 Best Places to Work by Glassdoor!

We have an opening for a researcher in the area of tokamak plasma physics for magnetic-fusion-energy. The research aims to develop a predictive understanding of MHD stability and its control in tokamak operating scenarios relevant to ITER or future advanced-tokamak (AT) burning plasmas. This will be done by combining modeling, simulation, experimentation, and detailed analysis of present-day tokamaks, and then comparing these to plasma theory. The primary experimental facilities used will be DIII-D (San Diego, USA), and to a lesser extent, international facilities including EAST (Hefei, PRC). This position is in the Physics Division.
The primary work location for this assignment will be in Livermore, California.

Essential Duties
- Lead and perform efforts to develop validated MHD stability models and stability controls that improve tokamak performance in present experiments and inform future devices.
- Develop or improve tokamak equilibrium and stability modeling and simulation tools (i.e., codes and workflows) that enable these efforts.
- Support the design, implementation, analysis, and modeling of experiments to improve understanding of requirements for avoiding or managing key MHD instabilities (e.g. tearing modes, locked modes, kink modes, edge localized mode, etc.) in plasmas relevant to ITER and future steady-state AT reactors. 
- Participate in DIII-D experimental activities both remotely and by frequent-but-flexible travel to San Diego, CA (e.g., approximately 1 week every 4 to 8 weeks would be appropriate).
- Conduct complex research on the EAST tokamak, including typically 1 or 2 trips to China per year of length 1-2 weeks each.
- Routinely interact with plasma theorists at LLNL and elsewhere to increase coupling between experiment and theory in the area of MHD stability
- Publish research results in peer-reviewed scientific or technical journals and present results at external conferences, seminars, and/or technical meetings
- Perform all assignments in accordance with ESH&Q, Security, and business practice requirements and policies.
- Perform other duties as assigned.

- PhD in physics or related field, or the equivalent combination of education and related experience.
- Advanced knowledge of basic plasma physics, tokamak operation, equilibrium, and stability.
- Significant experience beyond the post-doctoral level working on tokamak MHD stability experiments, analysis and modelling.
- Experience writing software to develop and use tokamak stability analysis and modeling tools in languages such as Python, IDL, or MATLAB.
- Record of documented publication record in peer-reviewed journals.
- Advanced verbal and written communication skills necessary to work in a multidisciplinary team environment, author technical and scientific reports and publications, and deliver scientific presentations.
- Ability to author or coauthor proposals for new research funding.
- Experience collaborating with both plasma theorists and plasma diagnosticians
- Experience contributing to proposals to federal research funding opportunity announcements.
Desired Qualifications
- Experience with codes commonly used to model tokamak equilibria and stability or interpret their data, e.g. EFIT, CORSICA, GPEC, DCON, STRIDE, TM1, OMFIT
- Experience interpreting measurements of plasma stability response to various actuators, such as 3D magnetic perturbations, and localized current drive.
- Involvement with International Tokamak Physics Activity (ITPA) joint experiments or modeling activities on tokamak stability.

Pre-Employment Drug Test:  External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test.  This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.

Security Clearance:  None required.

However, if your assignment is longer than 179 days cumulatively within a calendar year, you must go through the Personal Identity Verification process.  This process includes completing an online background investigation form and receiving approval of the background check.  (This process does not apply to foreign nationals.)

Note:   This is a Career Indefinite position. Lab employees and external candidates may be considered for this position.
