Bifurcated Helical Core Equilibrium States in Tokamaks

Olivier Sauter, Basil Duval, Stefano Coda, Jonathan Graves, Wilfred Anthony Cooper, Holger Reimerdes, Benoît Labit, Antoine Pochelon, David Pfefferlé, Federico David Halpern, Daniele Brunetti, Jonathan Rossel, Mattia Albergante

Tokamaks with weak to moderate reversed central shear in which the minimum rotational transform

q_{min}

is in the neighbourhood of unity can trigger bifurcated MagnetoHydrodynamic (MHD) equilibrium states, one of which is similar to a saturated ideal ...

Three-Dimensional Corrugation of the Plasma Edge when Magnetic Perturbations are Applied for Edge-Localized Mode Control in MAST

Wilfred Anthony Cooper

The distortion of the plasma boundary when three-dimensional resonant magnetic perturbations (RMPs) are applied has been measured in MAST H-mode plasmas. When the n = 3 RMPs are applied to control edge-localized modes (ELMs), the plasma experiences a stron ...

From astrophysics to fusion plasmas: signal processing and system optimization analysis for ITER

Duccio Testa

Efficient, real-time and unsupervised data analysis is one of the key elements for achieving scientific success in complex engineering and physical systems, of which three examples are the currently operating Joint European Torus (JET) and the soon-to-be-b ...

Low-frequency linear-mode regimes in the tokamak scrape-off layer

Paolo Ricci, Sébastien Jolliet, Federico David Halpern, Annamaria Mosetto

Motivated by the wide range of physical parameters characterizing the scrape-off layer (SOL) of existing tokamaks, the regimes of low-frequency linear instabilities in the SOL are identified by numerical and analytical calculations based on the linear, dri ...

Nanoparticle Synthesis and Growth in a Continuous Plasma Reactor from Organosilicon Precursors

Elizabeth Buitrago Godinez

Silica-like nanoparticles are produced from four different organosilicon monomers HMDSO, TMDSO, TEOS and TMOS in a continuous non-equilibrium plasma reactor. The nanoparticle synthesis is studied as a function of the process pressure, plasma power, gas vel ...

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 ...

Extremely Shaped Plasmas to Improve the Tokamak Concept

Francesco Piras

Energy is essential for human existence and our future depends on plentiful and accessible sources of energy. The world population is fast growing and the average energy used per capita increases. One of the greatest challenges for human beings is that of ...

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 ...

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 ...

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 ...
