Cold atmospheric pressure plasma jets- charge carried by plasma bullets

Cold atmospheric pressure plasma jets are re-searched for applications in surface modification, synthesis, sterilization, medicine. Partially due to the relative ease of constructing a plasma jet, a great amount of work has been published on jets in a va-riety of gases, using excitation in a wide frequency range and in several typical geometries. Most com-monly reported on are descriptions of discharge dy-namics, densities of various reactive species, fol-lowed by gas temperature measurements, imaging of flow fields, and rarely electron densities and associ-ated electric fields. The first reported measurement of the electric field associated with plasma bullets has been performed by using a spectroscopic technique and published in 2011 by Sretenovic ́ et al [1], fol
