Multiscale modelling for tokamak pedestals [PDF]
Journal of Plasma Physics, 2018 Pedestal modelling is crucial to predict the performance of future fusion devices. Current modelling efforts suffer either from a lack of kinetic physics, or an excess of computational complexity. To ameliorate these problems, we take a first-principles multiscale approach to the pedestal.

Differential and Integral Models of TOKAMAK
Advances in Electrical and Electronic Engineering, 2004 Modeling of 3D electromagnetic phenomena in TOKAMAK with typically distributed main and additional coils is not an easy business. Evaluated must be not only distribution of the magnetic field, but also forces acting in particular coils.

Modelling the capacitance of the elongated plasma in tokamak
Scientific Reports, 2023 AbstractThe capacitance model suitable for the non-circular cross-section plasma is studied based on the capacitance model of the circular cross-section plasma. The coaxial elliptic-torus capacitor property is further derived and used to determine the capacity of non-circular cross-section tokamak plasma, such as EAST (Experimental Advanced ...

Transport Simulasion in a Burning Tokamak Plasma [PDF]
, 1992 A one-dimensional tokamak transport code (TASK/TR) has been developed to analyze the evolution of a burning plasma accompanied with fusion reaction. This code deals with the electrons, deuterons, tritons, thermalized α particles, fast α particles and ...

Runaway electron generation during tokamak start-up [PDF]
, 2022 Tokamak start-up is characterized by low electron densities and strong electric fields, in order to quickly raise the plasma current and temperature, allowing the plasma to fully ionize and magnetic flux surfaces to form.

Representation and modeling of charged particle distributions in tokamaks [PDF]
Computer Physics Communications, 2022 Experimental diagnostics, analysis tools and simulations represent particle distributions in various forms and coordinates. Algorithms to manage these data are needed on platforms like the ITER Integrated Modelling & Analysis Suite (IMAS), performing tasks such as archiving, modeling, conversion and visualization. A method that accomplishes some of

Computer Modelling of Boundary Plasmas in Tokamaks
Journal of Nuclear Science and Technology, 1990 Details of the numerical modelling and method of the UEDA code which was developed for the analysis of the boundary plasma are described. The code employs a two-dimensional dynamic fluid model for fuel and impurity ions. The transport of the neutral gas is solved with the Monte Carlo method and coupled to the fluid equations.
