As a member of the liquid metal experimental team, we are looking for an experimentalist with strong technical curiosity, rigor and precision to sustains and controls thick, gravity-defying, free-surface liquid metal flows inside the stellarator. This includes the production of innovative alloys and components such as special pumps for in-house experiments and, eventually, for production and sales.

Your main responsibilities are:

• Experimental responsibilities
  • Play a major role in demonstrating gravity-defying free-surface liquid metal flows.
  • Identify the relevant length-scales and time-scales of the flow instabilities taking place in in-house liquid metal experiments.
  • Build, operate and improve liquid metal devices and analyse their data. Devices might include liquid metal pumps, space- and time-resolved diagnostics of liquid metal thicknesses and flowrate (resistive, capacitive, etc.).
  • Scale up sensing, actuating and feedback solutions from small demonstrators to large industrial facilities in harsh environments. Maximize Reliability, Availability, Maintainability and Inspectability (RAMI).
  • Contribute to demonstrate open loop stabilization.
  • In collaboration with the control engineer, contribute to the design, building and testing of the closed-loop feedback system.
  • Contribute to the experimental demonstration of liquid metal flow control.
  • Participate to the design and procurement of the prototypes, including structural parts, motors, electrical components, vacuum devices, etc.
  • Contribute to the scale-up of Renaissance Fusion's integrated HTS-Liquid Metal demonstrator to industry-relevant scales.
  • Work with in-house material scientists and experimentalists to optimize the sensing and actuating electrodes, substrates, inlets, outlets, diagnostics ports and other parts in terms of wettability, resistance to corrosion, electric and thermal conductivity, flow perturbation etc.
  • Produce commercial grade liquid alloys and devices for liquid metals.

• Scientific outcome
  • Prepare scientific reports (presentations, posters, etc.) and represent Renaissance Fusion to scientific conferences and workshops
  • Participate in the writing of patents and scientific papers
  • Put forward proposals for collaborations and grants
  • Remain on the lookout for any scientific developments in his/her field of expertise
  • May supervise trainees or co-supervise PhD students

You are the ideal profile if:

• Education and professional experience
  • PhD or Master’s degree + equivalent experience in physics, nuclear, chemical or electrical engineering, materials science or related field
  • 2+ years of experimental research in one or more of the following topics: fluid dynamics, electrical engineering, metallurgy, control engineering
• Language requirement
  • Fluent in English (C1)
  • Knowledge (B1 or higher) of French is a plus
• Technical competencies
  • Strong understanding of electromagnetism and fluid dynamics
  • Research experience in magnetohydrodynamics of plasmas and/or liquid metals.
  • Research experience in multi-phase and/or multi-component flows
  • Experience in Finite Element Analysis (FEA) is a plus
  • Coding experience in Python, Matlab or other programming language
