Study of a helium atmospheric pressure dielectric barrier discharge at 100 kHz

摘要

A homogeneous atmospheric pressure glow discharge is obtained in helium at 100 kHz. The electrical characteristics of the discharge are measured and compared with the results of the model. The calculations agree well with the experiment when a small admixture of nitrogen is assumed and the destruction of the helium excimers is strong enough. A multi-peak structure of the current is observed at higher amplitudes of the external voltage.
