Atmospheric pressure plasma jets:properties of plasma bullets and the dynamics of the interaction with dielectric surfaces

Abstract

Cold atmospheric pressure plasma jets, although mostly researched for applications in surface treatment, are rarely investigated in the presence of a surface. This paper presents the properties of plasma bullets formed in the capillary as well as the dynamics of the propagation of the plasma on dielectric surfaces as a function of applied voltage amplitude, gas flow, jet source geometry and the travelling length of the bullet
