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 postdoctoral researcher in the area of advanced tokamak plasma physics for magnetic-fusion-energy. The research aims to develop a predictive understanding of fully non-inductive, high-beta operating scenarios by performing joint experiments and modeling on the EAST tokamak in Hefei, China, and the DIII-D tokamak in San Diego, U.S.A.  This position is in the Physics Division. 

The work location for this assignment will be in San Diego, California.

Essential Duties
- Perform predictive integrated modeling of EAST and DIII-D steady-state scenario discharges to help guide experiments.
- Support the design, implementation, analysis, and modeling of steady-state scenario experiments on EAST and DIII-D, with 50% effort on each of the two devices. This will typically include 1 or 2 trips to China per year of length 1-2 weeks each, in addition to occasional participation using a remote-control room located in San Diego.
- Participate in the ongoing analysis and modeling tools for EAST, in collaboration with EAST colleagues and/or other U.S.-based institutions.
-Work with collaborators on both devices to design and carry out experiments exploring the optimization of high beta, fully non-inductive operation with enhanced energy confinement, compatible with boundary requirements, that projects to a future reactor.
- Compare experimental results to physics models to identify needed model improvements, missing physics, or benchmark/validate models.
- 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.

- Recent PhD in physics or a related field. 
- Knowledge of basic plasma physics, tokamak operation, equilibrium, stability, transport, NBI and RF heating and current drive.
- Experience carrying out experiments in magnetically confined plasma devices.
- Experience carrying out modeling of magnetically confined plasmas, especially equilibrium, transport, stability, and current drive.
- Experience writing software to develop plasma modeling tools and with data analysis programming language, such as IDL, Python, or MatLab.
- Documented publication record in peer-reviewed journals. 
- Proficient verbal and written communication skills necessary to work in a multidisciplinary team environment, author technical and scientific reports and publications, and deliver scientific presentations. 
- Experience working independently and in a team environment to achieve program goals in a timely fashion.
Desired Qualifications
- Experience carrying out core plasma physics experiments in a large tokamak.
- Experience with codes commonly used to model tokamaks or interpret their data, e.g. EFIT, DCON, TRANSP, GENRAY/CQL3D.
- Experience collaborating with theorists and diagnosticians.

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 two year Postdoctoral appointment with the possibility of extension to a maximum of three years.  Eligible candidates are those who have been awarded a PhD at time of hire date.
