Electrical parameters of the streamers of the nonequilibtium atmospheric plasma jets

Summary form only given. Recently a great attention is attracted to the creation of the small size nonequilibrium atmospheric plasma jets and their interaction with living tissue. This facilitates the development of appropriate tools for their diagnostics. The diagnostic tools that have been traditionally utilized for characterization of cold nonequilibrium atmospheric plasma jets include intensified charge-coupled device (ICCD) cameras, optical emission spectroscopy and electrical measurements of the discharge propertied. It was observed that streamer (“plasma bullet”) propagating along with gas flow is generated immediately after the breakdown. Recently a new method for temporally resolved measurements of absolute values of plasma density in the plasma column of small-size atmospheric plasma jet utilizing Rayleigh microwave scattering was proposed.^1,2
