Analysis and modelling of momentum transport based on NBI modulation experiments at ASDEX Upgrade

Basil Duval, Emiliano Fable, Giovanni Tardini

The prediction of plasma rotation is of high interest for fusion research due to the effects of the rotation upon magnetohydrodynamic (MHD) instabilities, impurities, and turbulent transport in general. In this work, an analysis method was studied and vali ...

Electron-cyclotron resonance heating and current drive source for flux-driven gyrokinetic simulations of tokamaks

Stefano Coda, Laurent Villard, Stephan Brunner, Joan Decker, Jean Arthur Cazabonne

Electromagnetic waves that resonate with the cyclotron motion of electrons in a magnetized plasma can efficiently transfer their momentum and energy to the plasma. This is routinely used to heat or drive current in tokamak plasmas. The impact of this local ...

ICRF modelling in 2D and 3D magnetic configurations using a hot plasma model

Jonathan Graves, Wilfred Anthony Cooper, Mike Machielsen

The generation of energetic trapped ions is important for experiments investigating their confinement in 3D magnetic fields, for plasma heating, for studies into unwanted drive of instabilities, and improved transport regimes. An effective way to generate ...

Integration concept of an Electron Cyclotron System in DEMO

Minh Quang Tran, René Chavan, Hartmut Zohm, Konstantinos Avramidis

The pre-conceptual layout for an electron cyclotron system (ECS) in DEMO is described. The present DEMO ECS considers only equatorial ports for both plasma heating and neoclassical tearing mode (NTM) control. This differs from ITER, where four launchers in ...

Physics and applications of three-ion ICRF scenarios for fusion research

Henri Weisen, Javier García Hernández, Mikhail Maslov, Samuele Mazzi

This paper summarizes the physical principles behind the novel three-ion scenarios using radio frequency waves in the ion cyclotron range of frequencies (ICRF). We discuss how to transform mode conversion electron heating into a new flexible ICRF technique ...

Structural pre-conceptual design studies for an EU DEMO equatorial EC port plug and its port integration

Minh Quang Tran, René Chavan

For the EU DEMO Tokamak, Electron Cyclotron (EC) launching systems for plasma heating and stabilization are under development. Various concepts for the optical system are currently studied of which the Mid Steering Antenna (MSA) with a steering mirror at a ...

Towards large area CVD diamond disks for Brewster-angle windows

Minh Quang Tran, Konstantinos Avramidis

In the frame of the EUROfusion Work Package Heating and Current Drive (WP HCD) of the Power Plant Physics and Technology (PPPT) program, CVD diamond disk Brewster-angle windows for gyrotron operation at multi-megawatt RF power levels and long pulses are un ...

Diamond Window Technology for Electron Cyclotron Heating and Current Drive: State of the Art

Konstantinos Avramidis

Nuclear fusion power plants require electron cyclotron (EC) heating and current drive (H&CD) systems for plasma heating and stabilization. High-power microwave beams between 1 and 2?MW generated by gyrotrons propagate in a dedicated waveguide transmission ...
