A phenomenological explanation for the anomalous ion heating observed in the JET alpha-heating experiment of 1997

Duccio Testa, Mattia Albergante

In the so-called alpha-heating experiment performed on the JET tokamak during the deuterium-tritium campaign of 1997, the ion temperature was found to be far exceeding (both in absolute value and in its rise time) the level that could have been expected ...

The ITER Thomson scattering core LIDAR diagnostic

The central electron temperature and density of the ITER plasma may be determined by Thomson scattering. A LIDAR topology is proposed in order to minimize the port access required of the ITER vacuum vessel. By using a LIDAR technique, a profile of the elec ...

A new approach to plasma profile control in ITER

Jonathan Bryan Lister, Sun Hee Kim

Advanced tokamak operation in ITER, such as the steady-state and hybrid modes, requires an active realtime feedback control of plasma profiles to achieve the advanced regimes for sustained operation. In this work, we have explored a potentially robust cont ...

Assessment of turbulent beam ion redistribution in tokamaks through velocity space-dependent gyrokinetic analyses

Ambrogio Fasoli, Jonathan Graves, Wilfred Anthony Cooper, Stephan Brunner, Mattia Albergante

We present the interface between a gyrokinetic code and a guiding centre code dedicated to the study of fast ion turbulent transport. A set of velocity space-dependent (kinetic) transport quantities, representing the link between the two codes, is presente ...

Using APCS for Plasma Vertical Control at TCV

Basil Duval, Stefano Coda, Jean-Marc Moret, Federico Alberto Alfredo Felici, James Paley, Francesco Piras

Early tokamaks with circular cross-section plasmas were vertically stable in nature and no problems were reported on the control of the vertical position. However, the concept of vertically elongated plasma cross-section, with benefits to the energy confin ...
