Effect of Ion Irradiation on the Surface Electrical Conductivity of Cucrzr at High Frequencies

Timothy Goodman, Jean-Philippe Hogge, René Chavan, Jérémy Genoud, Avelino Mas Sanchez, Anastasia Xydou

The ohmic losses in the Electron Cyclotron Heating system of the DEMO nuclear fusion reactor depend on the surface electrical conductivity of the material at the frequency of the mm-wave beams generated in the gyrotrons. To reduce the ohmic losses, many co ...
