First equilibrium reconstruction for ITER with the code NICE
Blaise Faugeras, Jacques Blum, Cedric Boulbe
In this short paper we present the first application of the IMAS compatible code NICE to equilibrium reconstrution for ITER geometry. The inverse problem is formulated as a least s…
Minimization of an energy error functional to solve a Cauchy problem arising in plasma physics: the reconstruction of the magnetic flux in the vacuum surrounding the plasma in a Tokamak
Blaise Faugeras, Amel Ben Abda, Jacques Blum +1
A numerical method for the computation of the magnetic flux in the vacuum surrounding the plasma in a Tokamak is investigated. It is based on the formulation of a Cauchy problem wh…
Real-Time Equilibrium Reconstruction in a Tokamak
Jacques Blum, Cédric Boulbe, Blaise Faugeras
This paper deals with the numerical reconstruction of the plasma current density in a Tokamak and of its equilibrium. The problem consists in the identification of a non-linear sou…
Real-time identification of the current density profile in the JET Tokamak: method and validation
Didier Mazon, Jacques Blum, Cédric Boulbe +6
The real-time reconstruction of the plasma magnetic equilibrium in a Tokamak is a key point to access high performance regimes. Indeed, the shape of the plasma current density prof…
Real time plasma equilibrium reconstruction in a Tokamak
Jacques Blum, Cédric Boulbe, Blaise Faugeras
The problem of equilibrium of a plasma in a Tokamak is a free boundary problemdescribed by the Grad-Shafranov equation in axisymmetric configurations. The right hand side of this e…
Reconstruction of the equilibrium of the plasma in a Tokamak and identification of the current density profile in real time
Jacques Blum, Cedric Boulbe, Blaise Faugeras
The reconstruction of the equilibrium of a plasma in a Tokamak is a free boundary problem described by the Grad-Shafranov equation in axisymmetric configuration. The right-hand sid…
