Spatiotemporal forecasting of the edge localized modes in tokamak plasmas using neural networks

Machine Learning: Science and Technology
Artificial intelligence techniques have been increasingly adopted by the plasma and fusion science to address problems like plasma reconstruction, surrogate modeling, and tokamak/stellarator optimization.

Towards nonaxisymmetry; initial results using the Flux Coordinate Independent method in BOUT++ [PDF]

Fluid simulation of stellarator edge transport is difficult due to the complexities of mesh generation; the stochastic edge and strong nonaxisymmetry inhibit the use of field aligned coordinate systems.

What is a reversed field pinch?

, 2013
The reversed field pinch (RFP) is a magnetic configuration germane to the tokamak, that produces most of its magnetic field by the currents flowing inside the plasma; external coils provide only a small edge toroidal field whose sign is reversed with ...

Efficient calculation of self magnetic field, self-force, and self-inductance for electromagnetic coils with rectangular cross-section

Nuclear Fusion
For designing high-field electromagnets, the Lorentz force on coils needs to be computed in order to design suitable support structures, and the inductance should be computed to evaluate the stored energy and dynamics.
