The effect of triangularity on fluctuations in a tokamak plasma

Olivier Sauter, Stefano Coda, Laurie Porte

The effects of plasma shaping, in particular triangularity (d), on temperature fluctuations in the tokamak a configuration variable have been studied using the correlation electron cyclotron emission system. It has been found that, in ohmic discharges with ...

Load transfer mechanisms in CFRP ground anchors with multi-strap ends

Thomas Keller, Anastasios Vassilopoulos, Haifeng Fan

An investigation of the load-transfer mechanism in carbon fiber-reinforced polymer (CFRP) ground anchors with multi-strap ends was conducted based on experimental and numerical studies of one- and two-strap anchors. Differences in the strap geometry, i.e. ...

Self-consistent interaction of fast particles and ICRF waves in 3D applications of fusion plasma devices

Jonathan Marc Philippe Faustin

Tokamaks and stellarators are the most promising reactor concepts using the magnetic confinement to contain the plasma fuel. Reactors capable of sustaining deuterium-tritium (D-T) fusion reactions requires the confinement of a very high temperature plasma ...

Poloidal CX visible light plasma rotation diagnostics in TCV

Claudio Marini

Controlled thermonuclear fusion is the main goal of plasma physics. At the Swiss Plasma Center, the Tokamak `a Configuration Variable (TCV) constitutes the main experiment on fusion research, where high temperature plasmas are confined by means of magneti ...

Experimental study of plasma turbulence in the TCV tokamak

Zhouji Huang

This thesis presents an experimental investigation of electron density fluctuations in the TCV tokamak, primarily with the tangential phase contrast imaging (TPCI) diagnostic. The focus is to study the small-scale broadband turbulence in the plasma, which ...

Poloidal asymmetry in the narrow heat flux feature in the TCV scrape-off layer

Basil Duval, Stefano Coda, Ivo Furno, Paolo Ricci, Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler, Joaquim Loizu Cisquella, Jan Horacek, Federico Nespoli, Federico David Halpern, Cedric Kar-Wai Tsui

Heat flux profiles inferred from a reciprocating probe at the outer midplane of the TCV tokamak during inner wall limited discharges feature radial fall-off lengths that shorten near the last closed flux surface (LCFS) consistent with the so-called narrow ...

Understanding and suppressing the near scrape-off layer heat flux feature in inboard-limited plasmas in TCV

Ivo Furno, Paolo Ricci, Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler, Umar Sheikh, Richard Pitts, Jan Horacek, Federico Nespoli, Federico David Halpern, Cedric Kar-Wai Tsui, Kevin Henricus Annemarie Verhaegh, Roberto Maurizio

In inboard-limited plasmas, the scrape-off layer (SOL) shows two regions: the near SOL, extending a few mm from the last closed flux surface (LCFS), characterized by a steep gradient of the parallel heat flux radial profile, and a far SOL, typically some c ...

Geometric formulas for system codes including the effect of negative triangularity

Olivier Sauter

Formulas for the volume, poloidal and toroidal surfaces, poloidal length, plasma current, and hence average poloidal field, are determined using global parameters of tokamak plasmas. Previous formulas did not include systematically the effect of triangular ...
