An investigation of dielectric barrier discharge in Ar and Ar/NH3 mixture using cross-correlation spectroscopy

Popis výsledku v původním jazyce

Dielectric barrier discharges (BDs) are known to operate in two distinctive modes. The filamentary mode of BD is characterized by a large number of short lasting spatially bounded microdischarges. This type of discharge is typical for most cases of BDs at atmospheric pressure. Under some specific conditions another form of BD may arise. In this mode plasma uniformly covers the whole electrode area. This mode is usually referred to as the diffuse or homogeneous mode of BD. This work presents studies of the filamentary mode of BD in argon and its transition to the diffuse mode by ammonia addition. The discharges were investigated by means of cross-correlation spectroscopy. Particularly, the influence of electrode shape, discharge gap and the influence ofammonia admixture on discharge development were studied. The measurement offers results with high temporal and spatial resolution which are useful for comparison with results of numerical models.
