First results on the plasma fluctuations of the TORPEX device in the new magnetic field configurations

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Joaquim Loizu Cisquella, Fabio Avino, Annamaria Mosetto, Alexandre Dominique Bovet

The TORoidal Plasma EXperiment (TORPEX) is a basic plasma physics device where a Simple Magnetized Torus configuration (SMT) can be obtained superimposing a small vertical magnetic field component on the main toroidal field, resulting in open magnetic heli ...

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 ...

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 ...

Physics design of a saddle coil system for TCV

Yves Martin, Jean-Marc Moret, Jonathan Rossel

The upgrade project for TCV (Tokamak à Configuration Variable) includes the installation of a set of saddle coils, namely the saddle coil system (SCS), located and powered such as to create a helical magnetic perturbation. Using independent power supplies, ...

A Far-Infrared Polarimeter Diagnostic for the Measurement of the Poloidal Magnetic Field in the TCV Tokamak

Information about the poloidal field inside the plasma and about the current density profile is essential for the understanding of the behavior of tokamak plasmas. The poloidal field outside the plasma edge is easily measured by a set of magnetic coils, wh ...

Local and Global Eulerian Gyrokinetic Simulations of Microturbulence in Realistic Geometry with Applications to the TCV Tokamak

Xavier Lapillonne

In magnetically confined fusion devices, the energy and particle transport is significantly larger than expected from purely collisional processes. This degraded confinement mostly results from small-scale turbulence and prevents from reaching self-sustain ...

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 ...
