Design and Numerical Analyses of the M4 Steering Mirrors for the ITER Electron Cyclotron Heating Upper Launcher

Timothy Goodman, René Chavan, Matteo Vagnoni, Avelino Mas Sanchez

Four electron cyclotron heating upper launchers (ECHULs) will be used at ITER to counteract magnetohydrodynamic plasma instabilities by targeting them with up to 24 MW of mm-wave power at 170 GHz. This mm-wave power is injected through eight ex-vessel (EV) ...

Seismic analyses of the Double Closure Plate Sub-Plate for the ITER Electron Cyclotron Upper Launcher during the Vacuum Vessel baking scenario

Timothy Goodman, René Chavan, Matteo Vagnoni, Avelino Mas Sanchez

The Double Closure Plate Sub-Plate (DCPSP) was introduced in the Electron Cyclotron Upper Launcher (EC UL) design in order to minimize the openings exposing the interior of the Port Plug (PP) to the port cell; avoiding thus the near environment activation ...

Thermo-mechanical analysis of an ITER ECH&CD Upper Launcher mirror

Timothy Goodman, Matteo Vagnoni, René Chavan, Avelino Mas Sanchez

The Mirror one Lower (LM1) is part of the in-vessel quasi-optical beam propagation system for the ITER Electro Cyclotron (EC) Upper Launcher (UL), where eight beams are reflected through four mirrors during its passage to the plasma. The mirrors are groupe ...

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

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

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

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

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 ...
