Ideal and Resistive Impurity Parallel-velocity-gradient Instability

The presence of impurity ions in magnetically confined plasmas can significantly influence micro-instabilities, impacting cross-field transport and ultimately affecting fusion performance. In particular, Parallel Velocity Gradient (PVG) instability, common ...

Cross-calibration and first vertical ECE measurement of electron energy distribution in the TCV tokamak

Ambrogio Fasoli, Stefano Coda, Joan Decker, Arsène Stéphane Tema Biwole

This paper describes the first vertical electron cyclotron emission measurement of non-thermal electron distributions in the Tokamak à Configuration Variable. These measurements were conducted in runaway electron scenarios and in the presence of electron c ...

Conceptual design of a modular EC heating system for EU-DEMO

Timothy Goodman, Jean-Philippe Hogge, René Chavan, Anastasia Xydou, Cinta Lucia Marraco Borderas, Daniel Birlan, Marc Noël, Fabien Pierre Crisinel, Arnaud Clément

The European DEMO (EU-DEMO) reactor studies within EUROfusion aim to develop a fusion power plant concept. The large tokamak device needs an auxiliary heating power which, at the present stage, is provided by the Electron Cyclotron (EC) heating system with ...

Initial Results From the SPIDER Beamlet Current Diagnostic

Basile Marie Jacques Pouradier Duteil

Source for the production of ions of deuterium extracted from a radio frequency plasma (SPIDER) is the full-scale prototype for the ITER heating neutral beam (HNB) source. Beam operation in SPIDER, with the eventual aim of achieving 100-keV, 46-A hydrogen ...

Collisionless losses of fast ions in the divertor tokamak test due to toroidal field ripple

Matteo Vallar

In this paper we analyze fast ion motion in the divertor tokamak test (DTT) device (Albanese et al 2017 Nucl. Fusion 57 016010). It is planned that DTT will be heated through a mix of 45 MW heating power, including 15 MW negative-ion-based neutral beam hea ...

Discrete shedding of secondary vortices along a modified Kaden spiral

Karen Ann J Mulleners, Diego Francescangeli

When an object is accelerated in a fluid, a primary vortex is formed through the roll-up of a shear layer. This primary vortex does not grow indefinitely and will reach a limiting size and strength. Additional vorticity beyond the critical limit will end u ...
