Micron and submicron macroparticles are produced along with the plasma at vacuum arc cathode spots. Published data refer to the size range 0.2--100 {micro}m. The lower limit is determined by the resolution of the equipment used (usually scanning electron microscopes). In the present study the authors focus on the detection and characterization of nanosize macroparticles (nanoparticles) using atomic force microscopy and field-emission scanning electron microscopy. New information is gathered on material-dependent size distribution functions as well as on the effectiveness of magnetic filtering for nanoparticles.
