Studies of propagating slow waves in the ion cyclotron range of frequencies
Studies of propagating slow waves in the ion cyclotron range of frequencies
Heating magnetically confined plasma with electromagnetic waves in the ion cyclotron range of frequencies is an established method in fusion research. However, it was observed that ICRF heating can induce sputtering at the plasma facing components. This contaminates the plasma which then leads to unwanted radiation losses. The extrapolated plasma parameters in the first generation of fusion reactors are such that this problem might even elevate. It was the goal of this PhD thesis to study if the ICRF slow wave, a key ingredient in the line of arguments, can propagate in the edge of a reactor relevant tokamak.

Abstract

Heating magnetically confined plasma with electromagnetic waves in the ion cyclotron range of frequencies is an established method in fusion research. However, it was observed that ICRF heating can induce sputtering at the plasma facing components. This contaminates the plasma which then leads to unwanted radiation losses. The extrapolated plasma parameters in the first generation of fusion reactors are such that this problem might even elevate. It was the goal of this PhD thesis to study if the ICRF slow wave, a key ingredient in the line of arguments, can propagate in the edge of a reactor relevant tokamak.
