About Thea Energy:
Thea Energy is leveraging recent breakthroughs in stellarator physics and engineering to create a faster and simpler approach to commercializing fusion energy. The company is reinventing the stellarator using computer-controlled arrays of planar coils thereby replacing the intricate, complex modular magnets required in all other stellarator architectures. Thea Energy is on a mission to create a limitless source of zero emission energy for a sustainable future.
Position Overview:
We are seeking a highly motivated Plasma Physicist to join our team, focusing on the physics design of stellarator divertors. Our unique toroidally continuous X-point divertor provides a robust, high-performance exhaust solution, addressing one of the most significant challenges in stellarator magnetic confinement. This role involves analyzing and simulating the divertor region of stellarator magnetic fields and collaborating across disciplines to execute our divertor development program. The ideal candidate will possess a strong background in plasma physics, particularly plasma edge physics, plasma-material interaction, and optimization along with hands-on experience in experiments and analysis. Experience with fusion device experiments is a plus. You will work with a dynamic team, contributing to cutting-edge research and development within Thea Energy’s stellarator systems. Candidates from all levels of professional experience are encouraged to apply and will be thoroughly evaluated.
Key Responsibilities:
•
Optimize divertor magnetic and mechanical geometry and target plates using state-of-the-art computational tools.
•
Analyze edge magnetic geometry and provide feedback to the stellarator optimization and divertor engineering teams.
•
Develop and implement algorithms to simulate fluid plasma within complex magnetic edge topologies.
•
Develop and optimize divertor operation scenarios for the Eos stellarator.
•
Collaborate with cross-disciplinary teams to design effective stellarator divertor systems.
•
Perform data analysis and model validation to provide insights into physical mechanisms governing plasma behavior.
•
Prepare technical reports, presentations, and publications based on simulation results and optimization findings.
