“…A coaxial sleeve-type dielectric barrier discharge (CS-DBD) reactor composed of two coaxial quartz tubes was employed in our previous study [14][15][16], and the results showed high odor removal efficiency. However, this kind of DBD reactor encountered many difficulties in further industrial applications because of its limited processing capacity.…”

This study aimed to discuss the removal of hydrogen sulfide (H 2 S) with non-thermal plasma produced by a multilayer tubular dielectric barrier discharge reactor, which is useful in the field of plasma environmental applications. We explored the influence of various factors upon H 2 S removal efficiency (h H S 2) and energy yield (Ey), such as specific energy density (SED), initial concentration, gas flow velocity and the reactor configuration. The study showed that we can achieve h H S 2 of 91% and the best Ey of 3100 mg kWh −1 when we set the SED, gas flow velocity, initial H 2 S concentration and layers of quartz tubes at 33.2 J l −1 , 8.0 m s −1 , 30 mg m −3 and five layers, correspondingly. The average rate constant for the decomposition of hydrogen sulfide was 0.206 g m −3 s −1. In addition, we also presented the optimized working conditions, byproduct analysis and decomposition mechanism.

“…In simulation studies, the major focus in the previous research was on the single-gap PS discharge configuration. In recent years, the multi-gap PS discharge mechanism was studied through PIC simulations on the uniform electrode apertures 32 . The discharge current as the function of gap pressure was also simulated under irregular electrode apertures, as well as rectangular apertures to generate a sheet electron beam directly 16 , 33 , 34 .…”

A pseudospark (PS) discharge can generate an electron beam with a high current density. The electron beam can be self-focused by an ion channel and transported over a long distance without the need for an external magnetic field. Such features make it attractive to drive millimeter-wave/THz interaction circuits for the generation of high-power radiation from a compact device. This paper presents the experimental results on the generation and transportation of the PS-sourced beam with different cross-sections, as well as the differences of the PS-sourced beam with and without post acceleration. Its application in millimeter-wave/THz sources was demonstrated by the operation of extended interaction oscillators (EIOs) at different frequencies is presented.

“…This means that the current density at the surface of the hollow cathode and the plasma density inside the cathode cavity are extremely high. The main features of the discharge in such conditions are discussed in [22][23][24].…”

The paper deals with the investigations of the discharge in hydrogen in the conditions close to that for the trigger units of the pseudospark switches. The following modes of discharge sustaining are classified: the Townsend discharge, the suppressed glow discharge with hollow cathode, the intermediate mode of the gradual transition from the suppressed discharge to the ordinary glow discharge, and the ordinary discharge in which the negative glow plasma occupies the whole depth of the cathode cavity. As applied to the ordinary discharge, the theoretical model that offers a possibility to estimate the negative glow parameters is developed. In the current range (1.6–10) mA the electron densities in the negative glow region are (1.7–8.7) 108cm–3. The interpretation for the mechanism of the current passage to the anode is also proposed based on the model. In particular, the explanation of the fact that at a low discharge current the region of the positive column plasma near the flat anode appears is given.
