Introducing electromagnetic effects in Soledge3X
Contributions to Plasma Physics, Volume 64, Issue 7-8, August-September 2024.Abstract In the pedestal region, electromagnetic effects affect the evolution of micro‐instabilities and plasma turbulence. The transport code Soledge3X developed by the CEA offers an efficient framework for turbulent 3D simulation on an electrostatic model with a fixed magnetic field. The physical accuracy of the model is improved with electromagnetic

Structure of chaotic magnetic field lines in IR-T1 tokamak due to ergodic magnetic limiter
AIP Advances, 2018 In this paper we have studied an Ergodic Magnetic Limiter (EML) based chaotic magnetic field for transport control in the edge plasma of IR-T1 tokamak. The resonance created by the EML causes perturbation of the equilibrium field line in tokamak and as a

Toward plasma drifts in EMC3: Implementation of gradient, divergence, and particle tracing schemes
Contributions to Plasma Physics, Volume 64, Issue 7-8, August-September 2024.Abstract This paper presents a first implementation of gradient, divergence, and particle tracing schemes for the EMC3 code, a stochastic 3D plasma fluid code widely employed for edge plasma and impurity transport modeling in tokamaks and stellarators.

, 2015 A new functional model of the prototype of closed Li circuit for protection of the chamber wall was tested in T-11M tokamak by simultaneous use of the vertical Li limiter as an emitter of Li and a new longitudinal Li limiter as its collector.

On the power and size of tokamak fusion pilot plants and reactors
, 2015 It is generally accepted that the route to fusion power involves large devices of ITER scale or larger. However, we show, contrary to expectations, that for steady state tokamaks operating at fixed fractions of the density and beta limits, the fusion ...

Reconstruction of the equilibrium of the plasma in a Tokamak and identification of the current density profile in real time [PDF]
, 2011 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 physics of an ignited tokamak [PDF]
Fusion Engineering and Design, 1991 A next step device which can demonstrate long burn with a high probability of success is possible, without speculating on the accumulation of favorable effects and ignoring the other ones. From the data base available today this appears possible only with large devices such as NET, ITER or JIT.

Non-Axisymmetric Tokamak Plasma Equilibrium by 3-D Multi-Layers Method
Applied SciencesA three-dimensional (3-D) Multi-Layers Method (MLM) of an extension of the axisymmetric version has been developed to compute non-axisymmetric tokamak plasma equilibria with a separatrix.
