“…Figure 7 shows a plot of the power per unit length versus current obtained in the MSGAD. It is compared against data that was obtained experimentally during the evolution of a single cycle of a low-current gliding arc discharge [10]. The gliding arc discharge starts in a quasi-thermal state (peak value of current flowing through the plasma channel).…”

A magnetic field is used to stabilize a gliding plasma discharge for controlled study purposes. The design, development, voltage-current characteristics, rotational and vibrational temperature measurements and the presence of an 'overshooting' regime in the magnetically stabilized gliding arc discharge (MSGAD) were discussed in part I (Gangoli et al 2010 Plasma Sources Sci. Technol. 19 065003). This paper deals with further experimental quantification of the dimensional features, current densities and power dissipated per unit length in the MSGAD. Estimations are made of important plasma properties, such as electric field, average electron energies and densities, that provide insight into the non-equilibrium 'glow-like' nature of the MSGAD. Visual observations of the MSGAD when operated in helium at atmospheric pressure clearly show physical features similar to a non-equilibrium glow discharge.

“…Nonthermal pulsed plasma has a relatively high energy efficiency since the majority of electric energy in a pulsed plasma is utilized for the production of energetic electrons that activate background gas, rather than for heating. This technology has been widely studied for applications such as removal of NO, and SO, from combustion flue gas and destruction of organic compound in wastes (Eliasson and Kogelschatz, 1991b;Rea and Yan, 1993;Mutaf-Yardimchi et al, 1998;Oda et al, 1998;Puchkarev et al, 1998;Smulders et al, 1998;Sun et al, 1999;Urashima et al, 1999). A successful process of a nonthermal plasma process is the ozonc generation system that was developed by Siemens 100 years ago (Horvath et al, 1985).…”
