About the role
This principal scientist leads development of RF pre-ionization, the plasma startup method for the company's field-reversed configuration fusion generators. The work covers strategy, hardware and experiments, taking RF startup from an experimental concept to a reliable platform capability. The role reports to the director of plasma and nuclear science and helps shape the long-term technical roadmap.
What you'll do
- Own the development of RF pre-ionization for plasma startup, from concept and experimental design through validation and performance improvement
- Lead hands-on work on RF hardware, antenna and coupling design, diagnostics and operating procedures
- Optimize RF plasma sources to reach target density, stability and coupling efficiency
- Define the diagnostic approach for characterizing RF-driven plasma formation and startup performance
- Bring together input from plasma physics, controls, machine operations, electrical engineering and data science
- Work with technical leadership on roadmap planning and new startup concepts for future machines
Requirements
- PhD in physics, plasma physics, electrical engineering, aerospace engineering or a related field relevant to RF plasma systems or fusion experiments
- 10+ years in advanced lab or R&D settings, with substantial hands-on work on plasma generation, RF hardware and vacuum systems
- Deep expertise in RF plasma sources, antenna and coupling design, or RF-plasma interactions
- Strong plasma diagnostics background, including evaluating density, temperature, stability, coupling and current
- Proven record of independently leading complex experimental programs from concept to validation
- Recognized subject matter expertise in RF-assisted startup, pre-ionization or fusion-enabling hardware
Nice to have
