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.

The structure of magnetic fluctuations in tokamaks: Observations in the TEXT tokamak

Physics of Fluids B: Plasma Physics, 1991
The structure of the magnetic fluctuations in a tokamak has been determined from extensive measurements using a variety of probes outside the limiter in TEXT [Plasma Phys. Controlled Nucl. Fusion 27, 1335 (1985)]. The spectrum has been measured to 500 kHz, but little energy is present above 150 kHz.

Erosion and deposition in tokamaks

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1985
The flow of metal impurities from the wall and limiter to the plasma, and back towards the wall, is investigated using surface collection probes and subsequent surface analysis in order to understand impuritiy generation and impurity transport. Impurity fluxes and their scrapeoff lengths have been investigated for several years in a large number of ...

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

Tokamak to tokamak variation and collinearity in scaling laws

Nuclear Fusion, 1990
The large multiplicity of scaling laws which almost fit the data is associated with the near degeneracy of the data covariance matrix. The traditional analysis assumes that only discharge to discharge variations are important. Using Swamy's random coefficient model, tokamak to tokamak variations are included in the statistical analysis.

The KSTAR tokamak

17th IEEE/NPSS Symposium Fusion Engineering (Cat. No.97CH36131), 2002
The KSTAR (Korea Superconducting Tokamak Advanced Research) project is the major effort of the Korean National Fusion Program to design, construct, and operate a steady-state-capable superconducting tokamak. The project is led by Korea Basic Science Institute and shared by national laboratories, universities, and industry along with international ...

The Start-up of Tokamaks and the Tokamak Start-up

1986
Since I’m not a native speaker of English, I had to look for the exact meaning of “to start up” in a Dictionary. Webster’s new Twentieth Century Dictionary gives two meanings: (1) “to come into being”, and (2) “to cause (something) to begin running”. In the present case the topic of this meeting could be interpreted either as the startup of tokamaks or

The Advanced Tokamak

Science, 1998
We disagree with Alexander J. Glass's assertion (Letters, 19 June, p. [1817][1]) that the tokamak must be as large as the International Thermonuclear Experimental Reactor (ITER) to achieve sustained thermonuclear burn and that this does not bode well for the tokamak as a potential power-plant concept.

Advanced Tokamak Concepts

Fusion Technology, 1998
From a discussion of fusion reactor designs based on today`s well-established experience gained in the operation of large tokamaks, it is concluded that such reactors are economically not attractive. The physics involved in the various options for concept improvement is described and the main experimental results of current research are shortly ...
