Application of Thomson scattering to helicon plasma sources

Patrick Blanchard, Alan Howling, Ivo Furno, Yanis Andrebe, Alban Sublet, Rémy Jacquier, Riccardo Agnello

The possibility of performing electron density and temperature measurements in a high power helicon plasma is a crucial issue in the framework of the AWAKE (Advanced WAKefield Experiment) project, which demonstrates acceleration of particles using GeV m(-1 ...

Millimeter-wave beam scattering by edge-plasma density fluctuations in TCV

Stefano Alberti, Timothy Goodman, Ivo Furno, Benoît Labit, Paolo Ricci, Fabio Riva, Oulfa Chellaï, Emanuele Poli, Marcelo Baquero Ruiz

In magnetically confined fusion devices, the use of millimeter waves (mmw) at the electron cyclotron (EC) frequencies ranges from plasma diagnostics to plasma heating, current drive and core confinement preservation. For large tokamaks such as ITER, numeri ...

New capabilities of the incoherent Thomson scattering diagnostics in the TCV tokamak: divertor and real-time measurements

Patrick Blanchard, Basil Duval, Pierre-François Isoz, Pierre Lavanchy, Xavier Llobet, Blaise Marlétaz, Philippe Marmillod, Yanis Andrebe, Severino Antonioni, Federico Alberto Alfredo Felici, Steve Couturier, Joan Decker, Cristian Galperti

This work reports developments of the incoherent TS diagnostic capabilities in the Tokamak a Configuration Variable (TCV). Their goals are to (i) diagnose the TCV divertor region, and (ii) provide Te and ne profiles of the plasma bulk in real-time. These t ...

Selected highlights of ECH/ECCD physics studies in the TCV tokamak

Basil Duval, Timothy Goodman, Olivier Sauter, Stefano Coda, Federico Alberto Alfredo Felici, Doohyun Kim, Joan Decker, Donghyun Kim

The Tokamak a Configuration Variable, TCV, has used Electron Cyclotron Heating and Current Drive as its only auxiliary heating system for nearly two decades. In addition to basic plasma heating and current profiling, ECH and ECCD under either feedforward o ...

The ITER Thomson scattering core LIDAR diagnostic

The central electron temperature and density of the ITER plasma may be determined by Thomson scattering. A LIDAR topology is proposed in order to minimize the port access required of the ITER vacuum vessel. By using a LIDAR technique, a profile of the elec ...

Magnetic Reconnection Triggering Magnetohydrodynamic Instabilities during a Sawtooth Crash in a Tokamak Plasma

Wilfred Anthony Cooper, Jonathan Graves

Thomson scattering measurements with subcentimeter spatial resolution have been made during a sawtooth crash in a Mega Ampere Spherical Tokamak fusion plasma. The unparalleled resolution of the temperature profile has shed new light on the mechanisms that ...

Influence of non-Maxwellian velocity distributions during ECRH and ECCD on electron temperature measurements by Thomson scattering

Roland Behn, Olivier Sauter, Petri Nikkola, Igor Klimanov

Deposition of electron cyclotron waves at high-power densities for heating and current drive in a tokamak plasma generates a population of fast electrons and therefore the velocity distribution of the electron population will deviate from a Maxwellian. Apa ...
