The DIII-D National Fusion Facility is the U.S.’s principal magnetically confined fusion research facility, focusing om the exciting science of the burning plasma state and its control in preparation for ITER, and developing the path to self-driven fully non-inductive operation for future fusion reactors. It has a strong focus on underlying science, and the application of this to improve fusion performance.
We currently have an exciting opportunity for a Scientist to join the Plasma Control Group in the Experimental Sciences Division of the DIII-D National Fusion Facility. The group conducts leading edge research for a range of facilities around the world, including the DIII-D facility in San Diego, and the ITER device in France.
DUTIES & RESPONSIBILITIES:
Analysis of plasma, electromagnetic, and electromechanical systems for tokamak and non-tokamak applications; calculation of MHD equilibrium and stability characteristics of tokamaks; plasma modeling and simulation for control design;
Design and execution of tokamak experiments for study and development of optimized plasma scenarios, plasma response models, and control approaches
Design and analysis of control algorithms; development of realtime code for plasma control;
Signal processing and interpretation;
Design and assessment of next-generation fusion devices;
Participation in experimental operation of DIII-D and other tokamaks worldwide.
Publish in recognized scientific journals, present work at national level, pursue research projects, and work with and provide support to the wider DIII-D team in the above topic areas.
Performs other duties as assigned or required.
