The prospects of using carbon-graphite materials as construction elements of the microwave plasma diagnostic in a fusion reactor

The comparative study of working characteristics of some graphite and metallic components of SHF diagnostics, such as several kinds of antennae, plane reflectors and cylindrical waveguides are presented. To simulate the consequence of a plasma disruption in large tokamaks on graphite-made antenna, we tested two antennae (MPG and ARV kinds of graphite) on the influence of power plasma flow: W ≥ 1.10 MJ/m2 with the time duration Δt ≈ 0.1 ms. All results show that the prospects to use graphite elements in a reactor-scale fusion device are rather promising.
