(Sub)nanosecond transient plasma for atmospheric plasma processing experiments: application to ozone generation and NO removal

Voltage distribution over capacitively coupled plasma electrode for atmospheric-pressure plasma generation

When capacitively coupled plasma (CCP) is used to generate large-area plasma, the standing wave effect becomes significant, which results in the hindering of the uniform plasma process such as in a plasma etcher or plasma chemical vapor deposition. In this study, the transmission line modeling method is applied to calculate the voltage distribution over atmospheric-pressure CCP electrodes with ...

Plasma Technology for Removal of Pharmaceutical Compounds from the Environment

Experimental Study on Ozone Generation Using Dc Driven Micro- Plasma

A new type of ozone generator using a micro hollow cathode discharge has been developed. The electrode system consists of two thin metal cathodes and a ceramic spacer with center holes of a few100 mm diameter. The ozone generation efficiency increases up to 45 g/kWh at the ozone concentration of 7.6 g/Nm without any cooling systems by feeding highpressure oxygen. In this ozone generating system...

Flowing dusty plasma experiments: generation of flow and measurement techniques

A variety of experimental techniques for the generation of subsonic/supersonic dust fluid flows and means of measuring such flow velocities are presented. The experiments have been carried out in a Π-shaped dusty plasma experimental device with micron size kaolin/ melamine formaldehyde particles embedded in a background of argon plasma created by a direct current glow discharge. A stationary du...

Transient Phenomena in Plasma Torches and in Plasma Sprayed Coating Generation

D.C. plasma torches are more and more widely used for different applications among which cutting, welding and spraying are probably the most developed. For a long period it is mainly their static characteristics which have been considered and their applications were studied on a macroscopic scale. However many transient phenomena occur, the systematic study of which has started only a few years...
