OSTI ID:6824060
Air breakdown N/sub 2/ + signatures are studied over a range of air pressures from 0.4 to 150 Torr. Short microwave pulses of frequency 3 GHz, approx. 6 ns duration and approx. 0.5 GW peak power are focused to produce air breakdown in a pressure cell region removed from walls. Diagnostics include microwave power measurements, spectroscopy, photometry and CCD imaging. Spectral signature variation with pressure, in addition to breakdown phenomenology, is discussed. 65 figs.
