Analyzing the emission self-organized structure in gas discharge by photoelectric detect method

摘要

In gas discharge, various self-organized structures are formed as the applied voltage is increased. A noticeable phenomenon is that the system undergoes twice hexagon structure. One is observed in the lower voltage range and the other is in the higher voltage range. To study the intrinsic mechanism, the light signal, electric signal, and the emission spectrum of the two hexagons is measured by photoelectric detect method. The electric signal is detected by high-voltage probe. The light signal is measured distinguished in time and space by using diaphragm. The electron excitation temperature is measured using spectrum method. It is conclude that the forming mechanism of the two kinds of hexagon is different. The lower-voltage hexagon is a dynamic multiplex structure, while the higher-voltage hexagon is a single static structure. The excitation temperature of higher-voltage hexagon is higher than that of lower-voltage hexagon.
