Stabilization of ion-scale electrostatic drift-type modes with decreasing aspect ratio through major or minor radius in tokamaks

Nuclear Fusion
In the conventional tokamak with a high aspect ratio ( A ), turbulent transport is known to be dominated by the ion-scale electrostatic drift-type modes, such as the ion temperature gradient (ITG) or trapped electron mode (TEM). When tokamak type changes

Linear and quasi-linear modeling in view of ELM control in MAST-U including effects of error fields

Nuclear Fusion
Edge localized modes (ELMs) pose a critical challenge to the safety and performance of plasma-facing components in tokamaks due to their periodic expulsion of heat and particles.

Why Spherical Tokamak Receives Significant Attention?

IEEJ Transactions on Fundamentals and Materials, 2003
The tokamak with the aspect ratio less than 2 is called spherical tokamak (ST), since the plasma is naturally elongated and has a spherical shape. It is being theoretically and experimentally shown that ST has a high potential to confine the very high beta plasma (beta=plasma pressure/magnetic pressure). The blanket module can be easily replaced in ST.

Power balance and divertor asymmetries in the Super-X divertors of MAST-U using SOLPS-ITER

Nuclear Fusion
Spherical tokamaks (STs) present unique challenges and opportunities in the area of particle and power exhaust, intensified due to their more compact sizes.
