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.

Central Solenoid for Spherical Tokamak Globus-M

Fusion Technology, 1998
The central solenoid is a critical component of the spherical tokamak Globus-M (plasma major radius R = 0.36 m, plasma minor radius a = 0.24 m, aspect ratio R/a = 1.5, toroidal magnetic field BT ≤ 0.62 T, plasma current Ip ≤ 0.5 MA). The two-layer solenoid, 1312 mm long with a 200-mm outer diameter, is located between the 112-mm-diam inner rod of the ...

Electromagnetic Instabilities in Spherical Tokamaks

2023
Electromagnetic microinstabilities are likely to dominate transport in high β next generation spherical tokamaks (STs) such as STEP. While gyrokinetic (GK) simulations have thus far proven to be a very accurate tool in modelling turbulent transport in predominantly electrostatic regimes at low β, obtaining saturated nonlinear simulations of plasmas ...

The role of the spherical tokamak in clarifying tokamak physics

Plasma Physics and Controlled Fusion, 1999
The spherical tokamak (ST) provides a unique environment in which to perform complementary and exacting tests of the tokamak physics required for a burning plasma experiment of any aspect ratio, while also having the potential for long-term fusion applications in its own right.

Steady state operation of spherical tokamaks

Nuclear Fusion, 2000
For a fusion power plant to be economically and technologically attractive, it should be as compact as possible and capable of `steady state' operation. One approach is based upon the spherical tokamak (ST) concept. This configuration features many of the qualities of the conventional aspect ratio tokamak, such as good confinement and MHD stability ...

The Mega Amp Spherical Tokamak

Fusion Engineering and Design, 1999
Results from START at Culham have been very impressive and have triggered the construction of several new Spherical Tokamaks (R/a ≤ 1.5), including the Mega Amp Spherical Tokamak (MAST), which was given EURATOM approval in April 1996. MAST (R = 0.7 m, a = 0.5 m, k ∼ 2, I p ≤ 2 MA) is twice the size of START and will allow plasmas with cross-section ...

Results from the MAST spherical tokamak

Proceedings of the 19th IEEE/IPSS Symposium on Fusion Engineering. 19th SOFE (Cat. No.02CH37231), 2003
The MAST (Mega-Amp Spherical Tokamak) experiment has been operational since Jan 2000. Results from MAST are important both in evaluating the potential of future ST fusion devices, and in developing understanding of processes relevant to conventional aspect ratio tokamaks.

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 ...

Spherical tokamak power plant design issues

Fusion Engineering and Design, 2000
Abstract The very high β potential of the spherical tokamak has been demonstrated in the START experiment. Systems code studies show the cost of electricity from spherical tokamak power plants, operating at high β in second ballooning mode stable regime, is comparable with fossil fuels and fission.
