Studies of Electron Transport and Current Diffusion in Switched ECCD experiments on TCV

Olivier Sauter, Timothy Goodman, Stefano Alberti, Roland Behn, Emiliano Fable, Costanza Zucca

The aim of the present work is to provide a better insight on the magnetic shear profile modification in the Switched ECCD experiments. Modelling of the plasma current density is carried on by the ASTRA transport code employed in both predictive and interp ...

A new 3MW ECRH system at 105 GHz for WEST*

Timothy Goodman, Stefano Alberti, Jean-Philippe Hogge, Ioannis Pagonakis, François Jean Gaston Legrand

The aim of the WEST experiments is to master long plasma pulses (1000s) and expose ITER-like tungsten wall to deposited heat fluxes up to 10 MW/m2. To increase the margin to reach the H-Mode and to control W-impurities in the plasma, the installation of an ...

Overview on recent progress in magnetron injection gun theory and design for high power gyrotrons

Stefano Alberti, Minh Quang Tran, Jean-Philippe Hogge, Trach-Minh Tran, Ioannis Pagonakis, Jérémy Genoud, François Jean Gaston Legrand

The magnetron injection gun (MIG) is one of the most critical subcomponents in gyrotrons. The electron beam, which has the primary role on the gyrotron operation, is generated and configured at this part of the tube. The electron beam properties determine ...

Manufacturing and Tests of the European 1 MW, 170 GHz CW Gyrotron Prototype for ITER

Stefano Alberti, Jean-Philippe Hogge

An industrial 1 MW, 170 GHz continuous-wave (CW) gyrotron prototype has been manufactured in 2015 at Thales. The physical design is provided by the European GYrotron Consortium (EGYC) and is supported by the construction and the measurement of a modular sh ...

TWANG-PIC, a novel gyro-averaged one-dimensional particle-in-cell code for interpretation of gyrotron experiments

Stefano Alberti, Minh Quang Tran, Jean-Philippe Hogge, Jérémy Genoud, Trach-Minh Tran

A new gyrotron simulation code for simulating the beam-wave interaction using a monomode time-dependent self-consistent model is presented. The new code TWANG-PIC is derived from the trajectory-based code TWANG by describing the electron motion in a gyro-a ...

Linear and non-linear studies of spurious backward-wave instabilities in a smooth-wall gyrotron beam duct

Patryk Kaminski, Stefano Alberti, Trach-Minh Tran, Jérémy Genoud

Recently developed self-consistent models for beam-wave interaction simulations of a gyrotron oscillator are used to study spurious backward-wave instabilities in smooth-wall metallic beam ducts. Starting from a simple case with a basic geometry, the influ ...

Status and Experimental Results of the European 1 MW, 170 GHz Industrial CW Prototype Gyrotron for ITER

Stefano Alberti, Minh Quang Tran, Jean-Philippe Hogge, Christian Schlatter, Ioannis Pagonakis

In the frame of a collaborative effort between the European GYrotron Consortium (EGYC), the European domestic agency Fusion for Energy (F4E) and the Industrial partner Thales Electron Devices (TED), the first continuous wave (CW) prototype of the EU gyrotr ...

Stacked rings for terahertz wave-guiding

Stefano Alberti, Jean-Philippe Ansermet, Jean-Philippe Hogge, Alessandro Macor, Emile Jacques de Rijk

We demonstrate the construction of corrugated waveguides using stacked rings to propagate terahertz frequencies. The waveguide allows propagation of the same fundamental mode as an optical-fiber, namely, the H E11 mode. This simple concept opens the way fo ...
