The diagnostic neutral beam injector with arc-discharge plasma source on the TCV Tokamak

Basil Duval, Alexander Karpushov, Yanis Andrebe, Alessandro Bortolon

The diagnostic neutral beam injector (DNBI) together with a charge exchange recombination spectroscopy (CXRS) system has been used on the TCV Tokamak as a diagnostic tool for local measurements of plasma ion temperature, velocity and carbon impurity densit ...

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 ...

Electrostatic turbulence and transport in a simple magnetized plasma

Ambrogio Fasoli, Benoît Labit, Mario Ludovico Podesta, Francesca Maria Poli, Gennady Plyushchev

Gradient driven electrostatic instabilities are investigated in TORPEX [A. Fasoli, B. Labit, M. McGrath, S. H. Muller, M. Podesta, and F. M. Poli, Bull. Am. Phys. Soc. 48, 119 (2003)], a toroidal device (R=1 m, a=0.2 m) in which plasmas are produced by mic ...

Collisionality and shear dependences of density peaking in JET and extrapolation to ITER

Ivo Furno, Henri Weisen, Alexey Zabolotskiy

Results from an extensive database analysis of JET density profiles in stationary conditions show that the density peaking factor n(e0)/< n(e)> in JET H modes increases from near 1.2 at high collisionality to around 1.5 as the plasma collisionality decreas ...
