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.

The Design of the Center Core of a Spherical Tokamak

Fusion Technology, 1997
Summary form only given. Spherical tokamaks are low-aspect-ratio devices with plasmas that are roughly spherical in shape. To create low-aspect-ratio plasmas, the center column of the tokamak must have as small a diameter as possible. The center column must include conductors to carry the toroidal field current and may also include space for an ohmic ...

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.

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 ...

Fast scanning probe for the NSTX spherical tokamak

Review of Scientific Instruments, 2009
We describe a fast reciprocating Langmuir probe and drive system, which has four main new features: (1) use of high-temperature, vacuum, circuit boards instead of cables to reduce weight and increase to 21 the number of possible connections, (2) rotatable and removable shaft, (3) 10 tip construction with designed hardware bandwidth up to 10 MHz, and (4)

Investigation of the electrical conductivity of a plasma in a spherical tokamak

Doklady Physics, 2004
A two-dimensional mathematical model is described by the Maxwell equations, balance equations and the Ohm law equation in cylindrical coordinates. An averaging is performed by virtue of integration along a magnetic surface. Penetration of the induced magnetic field into plasma is described by the diffusion equation.

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 ...

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 ...
