Neutral atom dynamics and plasma turbulence in the tokamak periphery
Understanding the physical mechanisms at play in the interaction between turbulent plasma and neutral particles is a crucial issue that we approach in this Thesis by using a first-principles self-consistent model of the tokamak periphery implemented in the ...
EPFL2017Ion cyclotron resonance heating for tungsten control in various JET H-mode scenarios
Jonathan Graves, Javier García Hernández
Ion cyclotron resonance heating (ICRH) in the hydrogen minority scheme provides central ion heating and acts favorably on the core tungsten transport. Full wave modeling shows that, at medium power level (4MW), after collisional redistribution, the ratio o ...
2017Physics and operation oriented activities in preparation of the JT-60SA tokamak exploitation
Stefano Coda, Timothy Goodman, Javier García Hernández, Marco Wischmeier, Kenji Tanaka, Leonardo Pigatto
The JT-60SA tokamak, being built under the Broader Approach agreement jointly by Europe and Japan, is due to start operation in 2020 and is expected to give substantial contributions to both ITER and DEMO scenario optimisation. A broad set of preparation a ...
2017CW Experiments With the EU 1-MW, 170-GHz Industrial Prototype Gyrotron for ITER at KIT
Stefano Alberti, Minh Quang Tran, Jean-Philippe Hogge, Christian Schlatter, Ioannis Pagonakis, Martin Schmid, Konstantinos Avramidis
The European 1-MW, 170-GHz continuous wave industrial prototype gyrotron for electron cyclotron resonance heating and current drive on international thermonuclear experimental reactor was during 2016 under test at the Karlsruhe Institute of Technology (KIT ...
Institute of Electrical and Electronics Engineers2017Beam Transfer Function measurements and transverse beam stability studies for the Large Hadron Collider and its High Luminosity upgrade
The motion of high energetic particle beams in accelerators is influenced by their interactions with the accelerator environment through electromagnetic fields induced by the particle passages. Traveling with a speed close to the speed of light, the partic ...
EPFL2017Plasma breakdown and current formation in single core and doublet configurations on TCV
This thesis presents an experimental investigation of the plasma formation in the TCV tokamak. The primary goal of this work was to program a reliable and smooth plasma formation at several positions within the TCV vessel and then use the gained understand ...
EPFL2017Distributed digital real-time control system for the TCV tokamak and its applications
Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Jean-Marc Moret, Federico Alberto Alfredo Felici, Cristian Galperti, Doohyun Kim, Himank Anand
A key feature of the new digital plasma control system installed on the TCV (Tokamak à Configuration Variable) tokamak is its possibility to rapidly design, test and deploy real-time algorithms. It accommodates hundreds of diagnostic inputs and actuator ou ...
2017H- ion source for CERN's Linac4 accelerator
Linac4 is the new negative hydrogen ion (H-) linear accelerator of the European Organization for Nuclear Research (CERN). Its ion source operates on the principle of Radio-Frequency Inductively Coupled Plasma (RF-ICP) and it is required to provide 50 mA of ...
EPFL2017Exploring drift effects in TCV single-null plasmas with the UEDGE code
Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler, Roberto Maurizio
This paper explores the effects of particle drifts across the magnetic field in TCV single-null plasmas using the two-dimensional edge plasma transport code UEDGE. In particular, it aims to reproduce a double-peaked density target profile, a feature which ...
Institute of Physics2017Modelling of advanced three-ion ICRF heating and fast ion generation scheme for tokamaks and stellarators
Jonathan Graves, Laurent Villard, Wilfred Anthony Cooper, David Pfefferlé, Jonathan Marc Philippe Faustin, Samuel Lanthaler
Absorption of ion-cyclotron range of frequencies waves at the fundamental resonance is an efficient source of plasma heating and fast ion generation in tokamaks and stellarators. This heating method is planned to be exploited as a fast ion source in the We ...
