Nearing final design of the ITER EC H&CD Upper Launcher

René Chavan, Timothy Goodman, Olivier Sauter, Jean-Daniel Landis, Robert Bertizzolo, Emanuele Poli, Florian Ramseyer, Matteo Vagnoni

The ITER ECRH system consists of 24 gyrotrons with up to 24 MW installed millimeter wave heating power at 170 GHz, power supplies, control system, transmission lines, one Equatorial and the four Upper Launchers. With its high frequency and small beam focus ...

Design and implementation of quasi-optical components for the upgrade of the TCV EC-system

Stefano Alberti, Timothy Goodman, Jean-Philippe Hogge, Laurie Porte, Matthieu Toussaint, Florian Ramseyer

The EC-system of the TCV tokamak is progressively being upgraded with the addition of two MW-class dual-frequency gyrotrons (84 and 126 GHz/2s/1MW). In order to connect the two gyrotrons to the existing low field side and top launchers, new waveguide routi ...

Design status of the double Closure Plate Sub-Plate concept for the ITER Electron Cyclotron Upper Launcher

René Chavan, Timothy Goodman, Jean-Daniel Landis, Avelino Mas Sanchez, Florian Ramseyer, Matteo Vagnoni

The Closure Plate Sub-Plate (CPSP), which defines the border between ex-vessel and in-vessel components of the Electron Cyclotron Upper Launcher (EC UL), bundles the waveguides into a sub-assembly which can be manipulated separately from the UL Port Plug ( ...

Thermal mechanical analyses of the mm-wave miter bend for the ITER electron cyclotron upper launcher first confinement system

René Chavan, Timothy Goodman, Jean-Daniel Landis, Avelino Mas Sanchez, Florian Ramseyer, Matteo Vagnoni

Each of the 4 ITER Electron Cyclotron Heating Upper Launcher (ECHUL) features 8 transmission lines used to inject microwave power of up to 1.31 MW (at the source) per line, into the plasma at 170 GHz. The microwaves are guided from the gyrotrons via (empty ...
