Simulations tackle abrupt massive migrations of energetic beam ions in a tokamak plasma
Nature Communications, 2018 Understanding the occurrence of sudden changes in plasma parameters is important for the operation of magnetically confined fusion devices. Here the authors use simulation to shed light on the formation of abrupt large-amplitude events and the associated

Prediction of the kinetic profiles in H-mode plasma discharges on EAST using core-pedestal coupling [PDF]
Scientific ReportsThe physical processes in tokamak plasma are strongly related to the coupling between the core and the pedestal. The accurate prediction of the kinetic profiles (electron temperature and density) from the pedestal to the core lays the physics basis for ...

A control oriented strategy of disruption prediction to avoid the configuration collapse of tokamak reactors [PDF]
Nature CommunicationsThe objective of thermonuclear fusion consists of producing electricity from the coalescence of light nuclei in high temperature plasmas. The most promising route to fusion envisages the confinement of such plasmas with magnetic fields, whose most ...

Linear optimal control of tokamak fusion devices [PDF]
Fusion Technology, 1989 The control of plasma position, shape and current in a tokamak fusion reactor is examined using linear optimal control. These advanced tokamaks are characterized by non up-down symmetric coils and structure, thick structure surrounding the plasma, eddy currents, shaped plasmas, superconducting coils, vertically unstable plasmas, and hybrid function ...
