摘要: An automated system for controlling the interelectrode gap of carbon arc and positioning plasma, constructed from commercially available components, is described. The core components are linear photodetector array, analog, digital integrated circuits, two direct current motors. It allows both maintaining constant its against optical axis plasma diagnostic arrangement. method operation demonstrated via production fullerenes nanotubes. This control contrivance has been used more than one year in bench scale with very satisfactory results. In addition, design presented here found to be simple construct readily merit being quite inexpensive, too (the entire cost under $2400).
