Paper Abstract

The formation, distribution and spectral properties of nanosecond surface corona discharges have been investigated. The discharges were initiated by fast-rising voltage pulses CdU/dt > 5x1012 V/s) in atmospheric' pressure air and nitrogen. Time-resolved measurements using sensitive photographic and photomultiplier techniques have shown that surface corona discharges can be established on the nanosecond time scale and can be distributed uniformly over large areas. Propagation speeds of up to 107 m/s have been measured. Spectrally resolved measurements show enhanced light emission at vacuum uv wavelengths below 140 nm. Due to these unique properties surface corona discharges can be used in applications such as large-area plasma electrodes and uv preionisation sources for high-pressure gas discharge lasers, nanosecond light sources for spectroscopy and high-speed photography as well as in multichannel surface discharge switches for low-inductance high-voltage switching.
