The ITER ECRH upper port antenna (or launcher) will be used to drive current locally for stabilising the neoclassical tearing mode (NTM)) by depositing mm-wave power inside of the island which forms on the q=3/2 or 2 rational magnetic flux surfaces and con ...

Design status of ITER ECH upper launcher mirrors

René Chavan, Jean-Daniel Landis, Francisco Sanchez, Joseph Duron

The ITER ECH upper launcher is devoted to directing up to 8 2NM beams per port plug over half of the plasma cross section. A focusing mirror is used to achieve a very narrow deposition profile to stabilize MHD activity such as the neoclassical tearing mode ...
