Tokamak in India

Science, 1996
In the News & Comment article “Korea plans new tokamak machine” by Jeffrey Mervis and Dennis Normile ([22 Dec. 1995, p. 1918][1]), there is no mention of the steady-state superconducting tokamak (SST) 1 being fabricated at the Institute for Plasma Research in Gandhinagar, India.

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 Topology of Tokamak Orbits*

Nuclear Fusion, 1979
Guiding-centre orbits in non-circular axisymmetric tokamak plasmas are studied in the constants of motion (COM) space of (v, ζ, ψm. Here, v is the particle speed, ζ is the pitch angle with respect to the parallel equilibrium current, J||, at the point in the orbit where ψ = ψm, and ψm is the maximum value of the poloidal flux function (increasing from ...

The Thor tokamak experiment

Il Nuovo Cimento B, 1981
The main characteristics of the plasma produced in Thor tokamak discharges are described. The machine performances are outlined and the experimental results relevant to the equilibrium, the stability and the control of the discharge regimes are discussed in detail.

Real-time systems in tokamak devices. A case study: The JET tokamak

2010 17th IEEE-NPSS Real Time Conference, 2010
The achievement of the required performances during the operation of large fusion experimental reactors, is strictly related to the flexibility and reliability of the real-time infrastructures. It turns out that, in tokamak reactors, the real-time infrastructure has to be designed so as to meet a number of common requirements.

Time-resolved spectroscopy in the Rijnhuizen Tokamak Project tokamak

Fusion Engineering and Design, 1997
Abstract At the Rijnhuizen 'rokamak Project tokamak spectrometers are used to diagnose the velocity distribution and abundances of impurity ions. Quantities can be measured as a function of time, and the temporal resolution depends on the line emissivity and can be as good as 0.2 ms for the strongest lines.

Equilibrium and stability of tokamaks

International Journal for Numerical Methods in Fluids, 1990
AbstractAxisymmetric, ideal MHD configurations with steady flow are computed by the finite‐element method. Rectangular elements with four to nine nodes are used. The equilibria are obtained in flux co‐ordinates by mesh rearrangement. The properties of the linearized motions around an equilibrium state are studied by a normal‐mode analysis.

Density fluctuations in the TORTUR Tokamak

Plasma Physics and Controlled Fusion, 1992
Quantitative measurements of the electron density fluctuation spectra, S(omega, k), are presented as a result of collective scattering measurements with 2 mm waves at various radial positions in the equatorial plane of the TORTUR Tokamak plasma. The spectra are determined in a wide frequency range up to 100 MHz and in a k-range between 400 and 4400 m-1

Microislands and transport in tokamaks

Journal of Plasma Physics, 2006
Kadomtsev proposed a self-generation mechanism of microislands (whose half-width is smaller than the Larmor radius of the ions) based on momentum and energy exchange between the electrostatic field of the islands and the ions of the background tokamak plasma.

Plasma Equilibrium in Tokamaks

Fusion Science and Technology, 1998
We have presented a theoretical description of toroidal equilibrium which involves the solution of the Grad-Shafranov equation and a careful choice of the parameters. The experimental counterpart is the production of accurate equilibrium data by means of all available diagnostics. To get agreement between these two is a long-term iterative process. The
