Experimental study of time dependence ablation rate in atmospheric pressure DC carbon arc discharges

In atmospheric pressure carbon arc discharges, anode ablation phenomena play an important role in synthesis of carbon nanostructures providing the feedstock of material. Experimental studies and theoretical modeling of the plasmasurface interaction processes near the anode are very difficult to carry out due to small dimensions, high energy fluxes and extreme states of the matter. These processes are intrinsic and formed self-consistently in anodic arcs including carbon synthesis arc. Therefore, it is important to characterize ablation processes to address arc stability issues and efficiency of feedstock material formation.
