“…At a certain threshold voltage the streamer-like discharge transitions to an unstable spark discharge regime. For the negative corona, increasing the applied voltage results in the formation of a steady state diffusive glow discharge and in a subsequent sparking [12]. By increasing the energy density, the RE for both negative and positive corona are increased ( Figure 2).…”

The decomposition of trichloroethylene (TCE) in air by non-thermal plasma was investigated with a multi-pin-to-plate direct current (DC) discharge at atmospheric pressure and room temperature. The effects of various operating parameters on the removal efficiency (RE) were examined. The experiments indicated that for low energy densities higher removal could be obtained with positive corona. For negative corona and 10% relative humidity (RH) a maximum RE of 99.5% could be achieved at 1100 J L -1 . Formation of byproducts was qualitatively analyzed in detail with FT-IR spectroscopy and mass spectrometry. Detected by-products for negative corona operated at 300 J L -1 and 10% RH include dichloroacetylchloride, trichloroacetaldehyde, phosgene, ozone, HCl, Cl 2 , CO and CO 2 . The highest RE for TCE was achieved with a relative humidity of 19%.

“…This makes the corona discharge being one of the important sources of electromagnetic interference (EMI) in electric power and electronic systems. It is therefore interesting and important to investigate the EM radiations from the corona discharges [3][4][5]. From the aspect of insulation condition monitoring, Chen et al studied the electromagnetic wave from corona discharge in needle-to-plate configuration [6].…”

-We investigate in this paper the radiated electromagnetic waves together with the discharge characteristics of Trichel pulse of negative DC corona discharge in air in pin-to-plate and wire-to-plate configurations. The feature of the current pulse and the frequency spectrum of the electromagnetic radiations were measured under various pressures and gas gaps. The results show that the repetition frequency and the amplitude of Trichel pulse current depend on the discharge conditions, but the rising time of the pulse relates only to the radius of needle or wire and keeps constant even if the other conditions (including the discharge current, the gas gap and the gas pressure) change. There exists the characterized spectrum of electromagnetic waves from negative corona discharge in Trichel pulse regime. These characterized radiations do not change their frequency at a given cathode geometry even if the averaged current, the gas gap or the air pressure changes, but the amplitude of radiations changes accordingly. The characterized electromagnetic radiations from Trichel pulse corona relate to the formation or the rising edge of current pulse. It confirms that the characterized radiations from Trichel pulse supply information of discharge system and provide a potential method for detecting charged targets.

“…Among multiple AP plasma sources, corona discharges [5] and dielectric barrier discharges [6,7] are known for their low gas temperature and low reactivity, as opposed to the high temperature counterparts such as gliding arc discharges [8] and arc plasma torches [9], which exhibit high reactivity and high gas temperature typically exceeding 10,000 K.…”

An atmospheric pressure nitrogen plasma jet sustained by a repetitive pulsed DC power source is studied. The afterglow characteristics of this plasma jet are studied by an optical emission spectrometer and thermocouples. The effects of the process parameters, namely the applied voltage and the gas flow rate, on the plasma characteristics are investigated. It is shown that the plasma reactivity is controlled by the power deposition to the plasma as well as the decay process of the reactive species upon formation. The reactivity increases with the increase in the applied voltage and with the decrease in the gas flow rate. The jet temperature is primarily controlled by the power density, and it increases with the increase in the applied voltage and with the decrease in the gas flow rate. These observations suggest that the plasma reactivity and the jet temperature of this plasma jet can be nearly independently controlled.
