Characterization of Light Emission From Electron-Beam-Generated Plasmas in Oxygen

In this paper, characterization of light emission from pulsed electron-beam plasmas in oxygen is presented. High-speed CCD images reveal light intensity evolution during a pulse. From the individual frames, averaged light intensities were calculated and compared with current measurements. As expected, the comparison suggests that excited species are produced mainly during the pulse. Optical emission spectrum indicates the type of excited species being produced.
