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 ...

Turbulent ion heating in TCV tokamak plasmas

Christian Schlatter

The Tokamak à configuration variable (TCV) features the highest electron cyclotron wave power density available to resonantly heat (ECRH) the electrons and to drive noninductive currents in a fusion grade plasma (ECCD). In more than 15 years of exploitatio ...

Analysis of plasma dynamic response to modulated electron cyclotron heating in TCV tokamak

Ilya Pavlov

The need of durable, economically acceptable and safe energy sources continues to stimulate studies in a field of thermonuclear fusion. The most successful solution for controlled magnetic fusion is the tokamak. The improvement of tokamak performance depen ...

Full Bootstrap Discharge Sustainment in Steady State in the TCV Tokamak

Olivier Sauter, Stefano Coda, Timothy Goodman

The Advanced Tokamak scenario, one of the modes of operation being considered for ITER, relies on the attainment of a high bootstrap current fraction. This scenario is typically characterized by an internal transport barrier (ITB). An internal feedback loo ...

Development of steady-state scenarios compatible with ITER-like wall conditions

Richard Pitts, Gilles Arnoux

A key issue for steady-state tokamak operation is to determine the edge conditions that are compatible both with good core confinement and with the power handling and plasma exhaust capabilities of the plasma facing components (PFCs) and divertor systems. ...

2007

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 ...

Plasma dynamics with second and third-harmonic ECRH and access to quasi-stationary ELM-free H-mode on TCV

Ambrogio Fasoli, Stefano Coda, Timothy Goodman, Yves Martin, Stefano Alberti, Patrick Blanchard, Laurie Porte, Henri Weisen, Mikhail Maslov, Andrea Scarabosio, Gilles Arnoux, Alessandro Bortolon

Intense electron cyclotron resonance heating (ECRH) and electron cyclotron current drive (ECCD) are employed on the Tokamak a Configuration Variable (TCV) both in second- and third-harmonic X-mode (X2 and X3). The plasma behaviour under such conditions is ...
