Progress on the design and manufacturing of the mirrors for the ITER Electron Cyclotron Heating and Current Drive upper launcher

Four of the 16 ITER upper port plugs will be devoted to electron cyclotron resonance heating (ECRH) in order to control the magneto-hydrodynamic (MHD) instabilities

Progress on the ITER Electron Cyclotron Heating and Current Drive Upper Launcher Steering Mirror Control System

The ITER ECRH upper launcher (UL) uses a steering mechanism assembly (SMA) to steer the beams in the appropriate location for controlling magnetohydrodynamic (MILD) activity in the plasma (NTMs and sawtooth oscillations)
