Abstract

For the investigation of filament-assisted CVD diamond coating processes, the knowledge of the role of atomic hydrogen seems of crucial importance. It is therefore desirable to determine absolute hydrogen atom concentrations and the influence of parameters like temperature, pressure, flow conditions etc. on the hydrogen atom distribution under typical conditions for this process.
