Arc discharge is commonly used for producing carbon nanostructures. Geometry of electrodes, the distance between them and ambient temperature are important factors, which determine the quantity and the variety of the formed carbon structures. Usually, two electrodes of different cross-sections (i.e. a thin anode and a thick cathode) are placed far away from each other, allowing a large vapour stream to be obtained, which then creates the nanostructures in the working chamber. However, if the two electrodes were placed closely together, carbon vapour would leave deposits on the cathode. These deposits consist of amorphous carbon and low quantities of carbon nanotubes. The later approach has not been widely studied although it has potential to be used for film depositions. The goal of this study is to understand how the distance between the electrodes influences the temperature and to determine the underlying processes, as well. Energy balance has been determined for two electrodes of equal cross-sections of 7.5 mm 2 . The experimental data needed for the calculation has been obtained for a distance of 0.5 mm between the electrodes.
