Abstract

Temporally resolved images acquired using a 5-ns gated intensified charge-coupled device camera show the dynamical behavior of a jet emanating from the end of a dielectric capillary operating at atmospheric pressure. Broadband emission and filtered emission from excited Ar, He, N2 and N2 + species were acquired. The properties of the highly localized so-called plasma bullets that make up the jet strongly resemble the properties of cathode-directed streamers in positive corona discharges.
