Numerical Simulation of Internal Reconnection Event in Spherical Tokamak

, 1999
"Three dimensional magnetohydrodynamic simulations are executed in a full toroidal geomety to clarify the physical mechanisms of the Internal Reconnection Event (IRE), which is observed in the spherical tokamak experiments.

Interharmonics: Theory and Modeling

, 2007
Some of the most remarkable issues related to interharmonic theory and modeling are presented. Starting from the basic definitions and concepts, attention is first devoted to interharmonic sources.

Multi-diagnostic characterization of neutrals in the confined region of DIII-D using interpretive DEGAS2 simulations

Nuclear Fusion
Measurements from multiple diagnostics are combined to constrain the density of neutrals in the confined plasma and improve our understanding of edge particle sources. Passive $\text{D}_\alpha$ emission spectrum measurements are obtained along tangential

Extension of the RAPDENS control-oriented model with a scrape-off layer particle balance model for ASDEX Upgrade and ITER

Nuclear Fusion
The plasma density is a key parameter in tokamak operation, as it influences plasma performance and stability. Hence, accurate real-time (RT) estimation and control are essential.

Problems in modeling TF ripple loss of fast alphas from a tokamak reactor [PDF]

, 1987
The present status of modeling TF ripple loss of fast alphas from tokamaks is summarized. The modeling issues are discussed, and several new aspects of this problem are described, including gyromotion, radial electric field, and sawtoothing.

Integrated modeling of electron cyclotron wave control of core impurity accumulation in HL-3 tokamak

Nuclear Fusion
Core impurity accumulation can severely degrade plasma confinement and may even lead to disruptions; therefore, its mitigation is essential for achieving stable high-performance operation in tokamak devices.

Determining the validity of tokamak perturbed equilibrium modeling using nonlinear equilibria

Nuclear Fusion
The prediction of perturbed equilibrium models for tokamaks with small non-axisymmetric fields is strongly dependent on which reference frame for axisymmetry is assumed.
