Job description

State-of-the-art simulations of transport effects in the fusion plasma edge has become an import element in the prediction of reactor-scale operational scenarios providing compatibility to both, required heat and particle exhaust constraints and good fusion plasma core performance. Given the multi-scale multi-physics nature of the problem, solutions for a reactor relevant operational regime are hard to achieve given slow numerical convergence rates. An employment of numerical tools, that e.g., allow to predict relevant dynamics for plasma control by using an integrated approach with suitable fidelity, are not yet existing. In very recent years, the fusion community has started to develop fast surrogate models based on Machine Learning / AI models to speed up significantly the employed tools. Such tools have demonstrated to be generally applicable and to be fast; their predictive capability however is a trade-off balancing speed and level of fidelity.

DIFFER is seeking to hire a post-doctoral researcher for approximately two years to work with the Integrated Modeling group at the institute within various frameworks (EUROfusion and other private partners in fusion) to conduct edge simulations for reactor design and improve fast edge transport model surrogates applicable to fusion reactors.




Responsibilities and tasks:
  • Employment of state-of-the-art tools to run plasma edge simulations
  • Development of ML/AI based fast surrogate models at increased fidelity, e.g. inclusion of a hierarchy of neutral physics and plasma drift flow effects in (partially existing) surrogates
  • Deploy the resultant improved and fast models and coupling of fast edge model e.g. to core plasma simulators
  • Uncertainty Quantification of assumed model parameters
  • Employment of reactor scale simulations

Required skills:
  • Good understanding of fusion edge plasmas transport physics
  • Experience with transport solvers (i.e. SOLPS-ITER)
  • Good knowledge of ML/AI based techniques to develop fast surrogates (deep neutral networks) and capability to develop own efficient model learning schemes (deep learning techniques, representation learning, active learning, etc)
  • (optional) Experience with dynamic simulations in the plasma edge

Conditions of employment
