Job summary

Realta Fusion Inc in Madison, Wisconsin, seeks a Senior NBI Scientist (Accelerator Physicist) to lead detailed beam-physics execution for Narsil and Hammir, and to design, test, and optimize neutral beam injection systems.

The role requires advanced accelerator physics expertise, hands-on beam diagnostics, and the ability to translate complex results into practical engineering recommendations while collaborating with engineering teams and mentoring junior scientists.

Qualifications

PhD or equivalent in accelerator physics or closely related field.
Strong knowledge of beam optics, extraction physics, perveance, emittance/divergence, electrostatic acceleration, and high-current beam transport.
Experience with accelerator grids, multi-aperture systems, magnetic transport, stripping/reionization, or neutral beam systems desirable.
Ability to independently perform calculations, modeling, parameter scans, and design trades and translate results into clear engineering recommendations.
Hands-on experience with beam diagnostics, testing, or accelerator commissioning preferred.

Responsibilities

Conduct detailed Narsil extraction, acceleration, and beam-transport physics analysis, including modeling and evaluation of ion extraction, beam acceleration, focusing, transport, and overall beam performance.
Provide detailed beam-physics analysis and design-trade support for Hammir, evaluating accelerator and beam-transport concepts, operating parameters, and design alternatives.
Develop, maintain, and improve accelerator and beam-physics modeling tools and supporting code used for system design, performance prediction, design trades, and interpretation of experimental results.
Mentor NBI Scientists in accelerator and ion-optical physics, providing technical guidance, reviewing analyses, and helping develop their capabilities in beam modeling, accelerator physics, and interpretation of experimental data.
