Stellarator Equilibrium Physicist

Start on/after: April 15, 2021
For full consideration, apply by: March 1, 2021
If a potentially good or excellent match, we will contact you within 1 week from applying.

 

Renaissance Fusion is the first Magnetic Confinement Fusion company in the EU, with the goal of solving the hardest and most rewarding energy problem: bringing fusion power to the grid. We are building the first net-energy producing stellarator by combining proprietary innovations in modular design, the manufacturing of next-generation High-Temperature Superconducting magnets, and liquid metal walls. We are forming a team of the brightest, most driven scientists and engineers to realize this mission within 11 years.

We are looking for a theoretical physicist to calculate the equilibrium properties of high-pressure, strongly magnetized stellarator fusion plasmas and help guide the design and realization of our reactor. The candidate will work closely with mathematicians and computer scientists calculating stellarator geometries and with physicists and engineers who will design easy-to-build stellarator coils according to said equilibria.

Our team is young, agile, international and based in the exciting city of Grenoble, by the French Alps.

Responsibilities:

  • Individual research responsibilities
    • Solve the 3D free-boundary plasma equilibrium problem with a magnetic field from a (provided) coil realization. Code, deploy and maintain equilibrium solver in our computational framework.
    • Predict/reconstruct equilibrium evolution during stellarator plasma’s start-up, ramp-up to high pressure and ramp-down.
    • Develop real-time, diagnostic-informed equilibrium reconstructions and predictions.
    • Identify threats from equilibrium-loss and ensure they are mitigated in the final design.
    • Create a self-consistent simultaneous solver of coupled equilibrium problems (plasma + liquid wall + coils).
    • Develop fast calculations of the stellarator “vacuum field” (in absence of plasma) in the form of 2D Poincaré maps and 3D renderings, as a zero-pressure approximation of full-fledged equilibria, using symplectic integrators, neural networks or other advanced methods.
  • Responsibilities as a team member
    • Generate 3D equilibria as targets for the coil-optimization problem. Eventually integrate plasma equilibrium calculations and coil-optimization.
    • Proactively and reactively provide equilibria and equilibrium expertise to the rest of the team, for example for the design of the stellarator coils, vacuum vessel, divertor, diagnostics, heating systems etc., or interpretation of experimental results.
    • Update equilibria according to new physics information and changes in design.
    • Calculate how equilibria modify under perturbations -to be discussed with colleagues- such as current drive, increases in heating and therefore beta.
    • Collaborate with colleagues on equilibrium-informed problems such as the ideal and resistive stability of the plasma, liquid metal stability and the coupled problem of plasma and liquid metal stability.

Qualifications -essential:

  • PhD in physics, mathematics or mathematical physics.
  • Research experience in 3D plasma physics or other complex 3D systems.
  • Analytical skills and good understanding of theoretical plasma physics and related mathematics such as calculus of variations.
  • Good scientific programming skills (e.g. in Python, C++, etc.). Experience with modern coding practices (CI, git) and interfacing legacy codes.
  • Ability to work independently as well as in a team.
  • Strong communication skills and a proven record of result dissemination at conferences.

Qualifications -desirable:

  • PhD in Plasma Physics.
  • Experience in analytical and/or numerical plasma equilibrium calculations, either 2D or, preferably, 3D.
  • Experience running or developing stellarator equilibrium codes (at least one of: VMEC, GVEC, SPEC, SIESTA, DESC).
  • Experience in scientific programming in Fortran.
  • Solid publication record in plasma theory, preferably in stellarator equilibrium analysis.
  • Experience in stellarator design.

Special emphasis will be laid on their thermal and electro-mechanical deformation, bearing in mind that magnetic fields will be 4x higher than in any stellarators to date. The forces on the coils might therefore be up to 16x higher, although coil-shape optimization, in collaboration with mathematicians, is greatly reducing that multiplier.
      • Ancillary systems for the manufacturing and operation of the above, including for example liquid metal pumps or heat exchangers.
    • Update and maintain simulation results, in coordination with the update and maintenance of design files.

    • Integrate in FEM simulations the input and feedback from a multi-disciplinary team of scientists and engineers.
    • Carry out multi-physics FEM simulations of other projects relevant to the company’s mission, as needed. Projects might include: fusion-enabling technologies (HTS, liquid metals), Metal Organic Chemical Vapor Deposition (MOCVD) machines for HTS film deposition, as well as non-fusion applications (medical imaging etc.).

  • 7 years or more of combined academic and professional experience in mathematics, physics, engineering or related field, e.g.:
    • Bachelor’s degree + 4 years of professional experience or
    • Master’s degree + 2 years of professional experience or
    • PhD degree
