Application of Thomson scattering to helicon plasma sources

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

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 ...

Experimental study of wakefields driven by a self-modulating proton bunch in plasma

Yiming Li, Ambrogio Fasoli, Ivo Furno, Patrick Blanchard, Alan Howling, Yanis Andrebe, Rémy Jacquier, Riccardo Agnello, Sun Hee Kim, Ishkhan Gorgisyan, Shuai Liu

We study experimentally the longitudinal and transverse wakefields driven by a highly relativistic proton bunch during self-modulation in plasma. We show that the wakefields' growth and amplitude increase with increasing seed amplitude as well as with the ...

Thomson scattering measurements in the divertor region of the TCV Tokamak plasmas

Basil Duval, Ivo Furno, Patrick Blanchard, Joan Decker, Xavier Llobet, Yanis Andrebe, Pierre Lavanchy, Riccardo Agnello, Steve Couturier, Severino Antonioni, Blaise Marlétaz, Pierre-François Isoz

In order to better study conventional and alternative divertor configurations, the TCV Tokamak was recently upgraded. In-vessel graphite baffles were installed in the TCV chamber to delimit a separate divertor chamber from the core that required enhanced d ...

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

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

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 ...

A Variable Structure Control Scheme Proposal for the Tokamak a Configuration Variable

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Timothy Goodman, Jonathan Graves, Yves Martin, Jean-Marc Moret, Ivo Furno, Duccio Testa, Minh Quang Tran, Paolo Ricci, Patrick Blanchard, Holger Reimerdes, Benoît Labit, Jean-Philippe Hogge, Christian Gabriel Theiler, Alessandro Pau, Federico Alberto Alfredo Felici, Laurie Porte, Alexander Karpushov, Antoine Pierre Emmanuel Alexis Merle, Joan Decker, Xavier Llobet, Umar Sheikh, Cristian Galperti, Christian Schlatter, Yanis Andrebe, Rémy Jacquier, Mengdi Kong, Francesco Carpanese, Henri Weisen, Yann Camenen, Jan Horacek, Marco Wischmeier, Nicola Vianello, Federico Nespoli, Fabio Riva, Cedric Kar-Wai Tsui, Kevin Henricus Annemarie Verhaegh, Wouter Vijvers, Anna Teplukhina, Roberto Maurizio, Zhouji Huang, Francesco Sciortino, Claudio Marini, Hoang Bao Le, Oulfa Chellaï, Himank Anand, Josef Kamleitner, Joyeeta Sinha, Bernhard Sieglin, Gergely Papp

Fusion power is the most significant prospects in the long-term future of energy in the sense that it composes a potentially clean, cheap, and unlimited power source that would substitute the widespread traditional nonrenewable energies, reducing the geogr ...

Dynamic modelling of local fuel inventory and desorption in the whole tokamak vacuum vessel for auto-consistent plasma-wall interaction simulations

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Jonathan Graves, Yves Martin, Duccio Testa, Patrick Blanchard, Alessandro Pau, Cristian Sommariva, Henri Weisen, Richard Pitts, Yann Camenen, Jan Horacek, Javier García Hernández, Marco Wischmeier, Nicola Vianello, Mikhail Maslov, Federico Nespoli, Yao Zhou, David Pfefferlé, Davide Galassi, Antonio José Pereira de Figueiredo, Jonathan Marc Philippe Faustin, Liang Yao, Dalziel Joseph Wilson, Hamish William Patten, Samuel Lanthaler, Eric Serre, Bernhard Sieglin, Otto Asunta

An extension of the SolEdge2D-EIRENE code package, named D-WEE, has been developed to add the dynamics of thermal desorption of hydrogen isotopes from the surface of plasma facing materials. To achieve this purpose, D-WEE models hydrogen isotopes implantat ...

Pedestal structure and energy confinement studies on TCV

Olivier Sauter, Basil Duval, Patrick Blanchard, Benoît Labit, Christian Gabriel Theiler, Antoine Pierre Emmanuel Alexis Merle, Umar Sheikh, Cedric Kar-Wai Tsui

High external gas injection rates are foreseen for future devices to reduce divertor heat loads and this can influence pedestal stability. Fusion yield has been estimated to vary as strongly as T-e,ped(2) so an understanding of the underlying pedestal phys ...

Gyrokinetic simulations of toroidal Alfven eigenmodes excited by energetic ions and external antennas on the Joint European Torus

Ambrogio Fasoli, Duccio Testa, Patrick Blanchard, Mikhail Maslov

The gyrokinetic toroidal code (GTC) has been used to study toroidal Alfven eigenmodes (TAEs) in high-performance plasmas. Experiments performed at the Joint European Torus (JET), where TAEs were driven by energetic particles arising from neutral beams, ion ...

Validation of the ICRF antenna coupling code RAPLICASOL against TOPICA and experiments

Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Yves Martin, Jean-Marc Moret, Duccio Testa, Patrick Blanchard, Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler, Alessandro Pau, Federico Alberto Alfredo Felici, Cristian Sommariva, Laurie Porte, Alexander Karpushov, Marc Gruber, Antoine Pierre Emmanuel Alexis Merle, Joan Decker, Umar Sheikh, Cristian Galperti, Yanis Andrebe, Haomin Sun, Richard Pitts, Yann Camenen, Jan Horacek, Roland Behn, Javier García Hernández, Marco Wischmeier, Nicola Vianello, Federico Nespoli, Antonio José Pereira de Figueiredo, Alberto Bottino, Emiliano Fable, Ben McMillan, Andrea Scarabosio, Cedric Kar-Wai Tsui, Doohyun Kim, Kevin Henricus Annemarie Verhaegh, Wouter Vijvers, Anna Teplukhina, Zhouji Huang, Dávid Wágner, Claudio Marini, Thomas Binderup Jensen, Hoang Bao Le, Himank Anand, Attila Bencze, Heinz Mueller, Donghyun Kim, Xiao Wang, Bernhard Sieglin, Otto Asunta, Hartmut Zohm, Emanuele Poli, Gergely Papp, Giovanni Tardini

In this paper we validate the finite element code RAPLICASOL, which models radiofrequency wave propagation in edge plasmas near ICRF antennas, against calculations with the TOPICA code. We compare the output of both codes for the ASDEX Upgrade 2-strap ante ...

Population modelling of the He II energy levels in tokamak plasmas: I. Collisional excitation model

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Jonathan Graves, Yves Martin, Duccio Testa, Patrick Blanchard, Alessandro Pau, Cristian Sommariva, Henri Weisen, Richard Pitts, Yann Camenen, Jan Horacek, Javier García Hernández, Marco Wischmeier, Nicola Vianello, Mikhail Maslov, Federico Nespoli, Yao Zhou, David Pfefferlé, Davide Galassi, Antonio José Pereira de Figueiredo, Jonathan Marc Philippe Faustin, Liang Yao, Dalziel Joseph Wilson, Hamish William Patten, Samuel Lanthaler, Bernhard Sieglin, Otto Asunta

Helium is widely used as a fuel or minority gas in laboratory fusion experiments, and will be present as ash in DT thermonuclear plasmas. It is therefore essential to have a good understanding of its atomic physics. To this end He II population modelling h ...
