Optimization of ICRH for core impurity control in JET-ILW

Ion cyclotron resonance frequency (ICRF) heating has been an essential component in the development of high power H-mode scenarios in the Jet European Torus ITER-like wall (JET-ILW). The ICRF performance was improved by enhancing the antenna-plasma couplin ...

High-beta, steady-state hybrid scenario on DIII-D

Holger Reimerdes

The potential of the hybrid scenario (first developed as an advanced inductive scenario for high fluence) as a regime for high-beta, steady-state plasmas is demonstrated on the DIII-D tokamak. These experiments show that the beneficial characteristics of h ...

Plans for the first plasma operation of Wendelstein 7-X

Wendelstein 7-X (W7-X) is currently under commissioning in preparation for its initial plasma operation phase, operation phase 1.1 (OP1.1). This first phase serves primarily to provide an integral commissioning of all major systems needed for plasma operat ...

A new generation plasma turbulence fluid code for tokamak scrape-off layer dynamics

Minh Quang Tran, Paolo Ricci, Joaquim Loizu Cisquella, Sébastien Jolliet, Federico David Halpern, Fabio Riva, Annamaria Mosetto, Christoph Wersal, Félix Benedito Clément Musil

Understanding the turbulent dynamics of the tokamak scrape-off layer (SOL) is critical for the safe operation of future fusion reactors. In this region of the tokamak device, the plasma exhausts particles and heat onto plasma facing hardware components, wh ...

The merits of ion cyclotron heating schemes for sawtooth control in tokamak plasmas

Jonathan Graves, Jonathan Marc Philippe Faustin

JET experiments have compared the efficacy of low-and high field side ion cyclotron resonance heating (ICRH) as an actuator to deliberately minimise the sawtooth period. It is found that low-field side ICRH with low minority concentration is optimal for sa ...

Real-time sawtooth control and NTM preemption in ITER

Olivier Sauter, Timothy Goodman, Doohyun Kim, Donghyun Kim

Real-time control of multiple plasma actuators is a requirement in advanced tokamaks; for example, for burn control, plasma current profile control and MHD stabilizationelectron cyclotron (EC) wave absorption is ideally suited especially for the latter. O ...

(N)TM Onset by Central EC Power Deposition in FTU and TCV Tokamaks

Olivier Sauter, Basil Duval, Duccio Testa, Holger Reimerdes, Alexander Karpushov, Cristian Galperti, Doohyun Kim, Dávid Wágner, Lucia Isabel Federspiel, Jonathan Rossel

The presence in plasmas of conventional and neoclassical tearing modes is a key problem for the confinement. The investigation of their onset is still an open issue to avoid plasma degradation and possible disruptions. The destabilization of the modes by ...
