FIRST EXPERIMENTS IN JET. Results obtained from JET since June 1983 are described which show that this large tokamak behaves in a similar manner to smaller tokamaks, but with correspondingly improved plasma parameters. Long-duration hydrogen and deuterium plasmas (>10 s) have been obtained with electron temperatures reaching > 4 keV for power dissipations < 3 MW and with * Euratom-IPP Association, Institut fur Plasmaphysik, Garching, Federal Republic of Germany. ** Euratom-ENEA Association, Centro di Frascati, Italy. *** Euratom-UKAEA Association, Culham Laboratory, Abingdon, Oxfordshire, United Kingdom. **** University of Dusseldorf, Dusseldorf, Federal Republic of Germany. + Euratom-Ris0 Association, Ris<f> National Laboratory, Roskilde, Denmark. ++ Euratom-CNR Association, Istituto di Física del Plasma, Milan, Italy. +++ Imperial College of Science and Technology, University of London, London, United Kingdom. ++++ Euratom-FOM Association, FOM Instituut voor Plasmafysica,.

Development of the indirect‐drive approach to inertial confinement fusion and the target physics basis for ignition and gain
TL;DR: In this paper, an approach to fusion that relies on either electron conduction (direct drive) or x rays (indirect drive) for energy transport to drive an implosion is presented.

Zonal flows in plasma—a review
TL;DR: A comprehensive review of zonal flow phenomena in plasmas is presented in this article, where the focus is on zonal flows generated by drift waves and the back-interaction of ZF on the drift waves, and various feedback loops by which the system regulates and organizes itself.

TL;DR: The 1990 National Academy of Science final report of its review of the Inertial Confinement Fusion Program recommended completion of a series of target physics objectives on the 10-beam Nova laser at the Lawrence Livermore National Laboratory as the highest priority prerequisite for proceeding with construction of an ignition-scale laser facility as mentioned in this paper.
Journal ArticleDOI
Influence of sheared poloidal rotation on edge turbulence
TL;DR: In this paper, the impact of radially sheared poloidal flows on ambient edge turbulence in tokamaks is investigated analytically, and a hybrid time scale weighted toward the former and the latter is found to govern the decorrelation process.
Journal ArticleDOI
Effects of E×B velocity shear and magnetic shear on turbulence and transport in magnetic confinement devices
TL;DR: The ExB shear stabilization model was originally developed to explain the transport barrier formed at the plasma edge in tokamaks after the L (low) to H (high) transition as mentioned in this paper.

An Empirical Approach to Tokamak Transport
TL;DR: In this paper, an overview of the important considerations related to particle and energy transport in a tokamak is presented, where the experimental data is analyzed in terms of the one dimensional magnetic field diffusion equation and the particle energy conservation equations.

Structure of edge-plasma turbulence in the Caltech tokamak
S. J. Zweben,Roy W. Gould +1 more
TL;DR: In this article, the spatial structure of the tokamak edge is characterized by very short auto-correlation times and short cross correlation lengths, i.e., the edge density fluctuations consist of small-scale turbulence.

Numerical simulation of electromagnetic turbulence in tokamaks
TL;DR: In this article, the time evolution of the perturbed electrostatic potential, densities, vector potential, and parallel ion motion of collisional and trapped electron plasmas in tokamak geometry is studied.

Theory of resistivity-gradient-driven turbulence
TL;DR: In this article, a theory of the nonlinear evolution and saturation of resistivity driven turbulence is presented, which evolves from linear rippling instabilities, and a nonlinear saturation mechanism is identified both analytically and numerically.

Theory of a weakly turbulent plasma
TL;DR: In this paper, the authors examined the damping (or growth) of the collective oscillations of a plasma wave, which is determined by the fine details of the particle distribution in phase space, for example by the derivative of the velocity distribution function.
