Identification of the ubiquitous Coriolis momentum pinch in JET tokamak plasmas

Henri Weisen, Yann Camenen, Mikhail Maslov

A broad survey of the experimental database of neutral beam heated plasmas in the JET tokamak has established the theoretically expected ubiquity, in rotating plasmas, of a convective transport mechanism which has its origin in the vertical particle drift ...

MHD equilibrium and stability of tokamaks and RFP systems with 3D helical cores

Olivier Sauter, Jonathan Graves, Wilfred Anthony Cooper

Bifurcated magnetohydrodynamic (MHD) equilibrium states are computed for ITER hybrid scenario and RFX-mod SHAx configurations with very flat or reversed core magnetic shear conditions. In the ITER studies, the minimum inverse rotational transform qmin is n ...

Pedestal Characteristics and MHD Stability of H-Mode Plasmas in TCV

Andreas Pitzschke

The tokamak à configuration variable (TCV) is unique in its ability to create a variety of plasma shapes and to heat the electron population in high density regimes using microwave power at the third harmonic of the electron cyclotron frequency. In the fra ...

KSTAR equilibrium operating space and projected stabilization at high normalized beta

Holger Reimerdes, Joo Yeon Kim, Ji Hyun Kim

Along with an expanded evaluation of the equilibrium operating space of the Korea Superconducting Tokamak Advanced Research, KSTAR, experimental equilibria of the most recent plasma discharges were reconstructed using the EFIT code. In near-circular plasma ...

Overview of physics results from NSTX

Holger Reimerdes, Mario Ludovico Podesta, Alessandro Bortolon, Anton Smirnov, Gang Yu, Maike Jaworski, Ji Hyun Kim, Bo Hu

In the last two experimental campaigns, the low aspect ratio NSTX has explored physics issues critical to both toroidal confinement physics and ITER. Experiments have made extensive use of lithium coatings for wall conditioning, correction of non-axisymmet ...

Real-Time Control of Tokamak Plasmas: from Control of Physics to Physics-Based Control

Federico Alberto Alfredo Felici

Stable, high-performance operation of a tokamak requires several plasma control problems to be handled simultaneously. Moreover, the complex physics which governs the tokamak plasma evolution must be studied and understood to make correct choices in contro ...

The Effect of Plasma Profile Variation on the Stability of the n = 1 Internal Kink Mode in Rotating Tokamak Plasmas

Jonathan Graves

The sensitivity of the stability of the ideal n = 1 internal kink mode to variations in the plasma profiles is analysed both analytically and numerically in rotating tokamak plasmas. These stability analyses have been carried out including the centrifugal ...
