FAIR-MAST: A fusion device data management system

SoftwareX
We are introducing FAIR-MAST, a data management system designed for historical diagnostic data from the Mega Ampere Spherical Tokamak (MAST) fusion experiments.

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.

Plasma self-driven current in tokamaks with magnetic islands

Nuclear Fusion
Magnetic island perturbations may cause a reduction in plasma self-driven current that is needed for tokamak operation. A novel effect on tokamak self-driven current revealed by global gyrokinetic simulations is due to magnetic-island-induced 3D electric

SOLPS-ITER simulations to study the impact of aspect ratio on edge fueling neutrals in tokamaks

Nuclear Materials and Energy
In this paper, we examine the role of the aspect ratio on the neutral penetration and poloidal distribution for fixed magnetic geometry and plasma profiles using SOLPS-ITER. We start from an H-mode discharge from MAST (Kirk et al., 2012), with its aspect

A coordinate free description of magnetohydrostatic equilibria [PDF]

The question what geometrical restrictions are imposed on static magnetic fields by the magnetohydrostatic (MHS) equation is addressed. The general mathematical problem is therefore to determine the solutions of the MHS equations in the corona subject to

Observation of a new pedestal stability regime in MAST Upgrade H-mode plasmas

Nuclear Fusion
The first pedestal stability and structure analysis on the new MAST Upgrade (MAST-U) spherical tokamak H-mode plasmas is presented. Our results indicate that MAST-U pedestals are close to the low toroidal mode number ( n ) peeling branch of the peeling ...

Neutronics analysis of spin-polarized fuel in spherical tokamaks

Nuclear Fusion
The effect of spin-polarized deuterium–tritium fuel on the blanket, magnets, and surrounding structures is analyzed for a spherical tokamak fusion power plant.
