Sr Scientist - Neutral Beams

Rostoker Lab, 19631 Pauling, Foothill Ranch, CA 92610, USA TAE is the world’s first private fusion energy company, founded in 1998 to commercialize the cleanest, safest, most affordable, and sustainable form of carbon‑free power. We are applying science and engineering to design transformational technologies. Whether it’s harnessing fusion through the science of stars, making exponential leaps in power efficiency, or innovating medical care with a novel cancer treatment, we’re turning the promise of science into reality. We’re looking for candidates who are passionate about realizing our mission: a future where all people have affordable access to reliable, abundant, and environmentally friendly fusion‑generated electricity. About The Role The next fusion machine in TAE – Da Vinci – requires a powerful nuclear‑beam injecting system. It has two types of neutral beams – low‑energy NB (tens of keV, 5 MW per beamline), based on a positive ion source, and high‑energy NB (1 MeV, 5 MW), based on a negative ion source. You will participate in the development of long‑pulse plasma sources (CW), extracting and accelerating systems, beamline components; conduct experiments with the plasma source and beam characterization; and do plasma generation and beam transport simulation. Key accountabilities Conduct low‑temperature plasma experiments and simulate plasma generation. Develop, study, and optimize ion‑beam optics. Develop the new NB for future plasma machines: conduct simulations of beam formation and transport; experiment with beam parameters, design NB systems with the engineering team, and test NB subsystems. Develop beamline systems – vacuum systems, beam dumps, neutralizers, etc. Develop diagnostics for the high‑power NB (secondary electron emission detectors, calorimeters, optical diagnostics, etc.). About You Experience with plasma sources, neutral beam injectors, and plasma/beam diagnostics. Experience with ion/electron accelerators and beam transport. Operation of high‑voltage equipment (>10 kV). Numerical simulation of plasma generators, ion/electron beam formation, beam transport, mechanical/thermal stresses. Experience with high‑vacuum systems, UHV. Experience with negative‑ion sources. Excellent analytical and data‑analysis skills. Experience in ion‑beam operation, development, and design. Hands‑on negative‑ion beam operation is preferred. Experience with programming languages/scripts/macros (Python, MATLAB, IDL, etc.) is also useful. Education PhD required; preferred in physics, plasma physics, engineering or a related field.
