Physics Insight from Plasma Shaping of TCV Tokamak Plasmas - focus on Electron Heat Transport

Antoine Pochelon

In the search of a fusion reactor using magnetic confinement of toroidal plasmas, many important plasma performance parameters directly depend on the shape of the plasma cross-section. The unique shaping capability of the TCV tokamak ("Tokamak à Configurat ...

Overview of physics research on the TCV tokamak

Ambrogio Fasoli

The Tokamak a Configuration Variable (TCV) tokamak is equipped with high-power (4.5 MW), real-time-controllable EC systems and flexible shaping, and plays an important role in fusion research by broadening the parameter range of reactor relevant regimes, b ...

Sources and detectors of fast ions for basic devices

Ambrogio Fasoli, Ivo Furno, Gennady Plyushchev

The physics of supra thermal test ions in turbulent plasmas can be conveniently studied in basic plasma physics devices, which allow high-resolution measurements of plasma and fast ion parameters and wave fields throughout the whole plasma cross-section. W ...

Electrostatic and magnetic transport of energetic ions in turbulent plasmas

Analytical and numerical work is used in tandem to address the problem of turbulent transport of energetic ions in magnetized plasmas. It is shown that orbit averaging is not valid under rather generic conditions, and that perpendicular decorrelation effec ...

Cross-field plasma blob motion in an open magnetic field line configuration

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Benoît Labit, Christian Gabriel Theiler, Gennady Plyushchev, Stefan Müller

The radial propagation of blobs generated from plasma instabilities is investigated in an open magnetic field line configuration. Blob cross-field velocities and sizes are obtained from internal probe measurements using pattern recognition. By varying the ...

Ion temperature fluctuations in ELMy H-mode of the X3 EC-heated plasmas on TCV

Basil Duval, Alexander Karpushov, Christian Schlatter

This paper focuses on interpreting variations in the NPA measured energy distribution of neutral fluxes from the TCV high density H-mode plasma discharges with strong third harmonic electron cyclotron heating (P_{X3}>P_{\Omega}). Two quasi-stationary regim ...

Chapter 4: Power and particle control

Richard Pitts

Progress, since the ITER Physics Basis publication (ITER Physics Basis Editors et al 1999 Nucl. Fusion 39 2137-2664), in understanding the processes that will determine the properties of the plasma edge and its interaction with material elements in ITER is ...

Chapter 2: Plasma confinement and transport

Yves Martin, Jing Li

The understanding and predictive capability of transport physics and plasma confinement is reviewed from the perspective of achieving reactor-scale burning plasmas in the ITER tokamak, for both core and edge plasma regions. Very considerable progress has b ...

Energetic particle physics studies on Alcator C-Mod

Ambrogio Fasoli, Yu Lin

Energetic particle physics is studied in Alcator C-Mod in reactor relevant regimes with high density and equilibrated electron and ion temperatures. Stable Alfven eigenmodes are excited with low-power active magnetohydrodynamic antennas in the absence of a ...
