The Mega Amp Spherical Tokamak

Proceedings of 16th International Symposium on Fusion Engineering, 2002
A Mega Amp Spherical Tokamak (known as MAST) is proposed to be constructed at Culham Laboratory. The aim is to continue the highly successful tight aspect ratio work pioneered on the START machine at Culham.

The spherical tokamak programme at Culham

Nuclear Fusion, 1999
The spherical tokamak (ST) is the low aspect ratio limit of the conventional tokamak and appears to offer attractive physics properties in a simpler device. The START (Small Tight Aspect Ratio Tokamak) experiment provided the world's first demonstration of the properties of hot plasmas in an ST configuration and was operational at Culham from January ...

Development of Next-Generation Spherical Tokamak Concept. The Globus-3 Tokamak

Физика плазмы, 2023
The concept of next-generation spherical tokamak is being considered: the Globus-3 project,which, in its characteristics, is compatible with the infrastructure existing at the Ioffe Institute, but differsfrom the currently operating Globus-M2 tokamak in the stronger toroidal magnetic field (1.5–3.0 T) andincreased duration of plasma discharge.

Progress on spherical tokamaks

Plasma Physics and Controlled Fusion, 1994
The history of low-aspect-ratio 'spherical' tokamak research is described and the advantages claimed for the concept are outlined and compared with experimental results from the START device and elsewhere. Further development of the spherical tokamak, and its potential for a materials test facility or ultimately a fusion plant, are discussed.

Physics of spherical tokamaks

Technical Physics, 1999
Spherical tokamaks are a limiting case of conventional tokamaks, combining simple design with attractive physical characteristics. Being of potential importance for the controlled nuclear fusion program in their own right, spherical tokamaks also contribute much to our understanding of the physics of conventional tokamaks.

The Way Forward for the Spherical Tokamak

Fusion Technology, 1996
The low aspect ratio or spherical tokamak offers the prospect of burning plasmas in a compact simple system at a lower cost than in conventional tokamaks. The promising results obtained on START and other small spherical tokamaks have led to the approval of higher current devices at the MA level where the key issues of operational limits, confinement ...

'Natural elongation' of spherical tokamaks

Nuclear Fusion, 1992
The variation of the elongation of axisymmetric plasma columns in vertical equilibrium magnetic fields is investigated as a function of the aspect ratio using the Solov'ev equilibrium model and the principle of virtual ...

Bootstrap Current in Spherical Tokamaks

Plasma Science and Technology, 2003
Variational principle for the neoclassical theory has been developed by including a momentum restoring term in the electron-electron collisional operator, which gives an additional free parameter maximizing the heat production rate. All transport coefficients are obtained including the bootstrap current.
