A parallel-plate atmospheric plasma generator has been built with discharge electrodes that also serve as a non-dispersive terahertz (THz) waveguide for plasma diagnostics based on THz time-domain spectroscopy. It has been confirmed that, in the system, a uniform glow-like atmospheric pressure plasma is generated and THz waves propagate as designed.
Summary form only given: Two models of plasma generator /reaction chamber/ with divergent channels have been designed and used in the laboratory testing. The arc was magnetically driven between co-axial electrodes of different shape and configuration making the nozzle conical or spiraling. These resulted in fast arc expansion and a thermal tail formation called the dispersed plasma. Some diagnostic...
This work investigates medical sterilization using plasma jet. An open-air coaxial plasma generator is designed and utilized to generate plasma jet using helium as the operating gas. The result of sterilization is evaluated using E. coli DH5. Our results show that the plasma jet produced by our system is effective on sterilization against bacteria. The sterilization outcomes are affected by the operating...
A micro-plasma generator for the detection of heavy metals in the water has been fabricated and evaluated. As for the new type of a plasma source, the micro-plasma generator based on water electrode has been proposed. This type of device features simple device structure that doesnpsilat require nebulizer for water samples. Water sample is isolated from a metal electrode by glass substrate, eliminating...
This paper is dedicated to characteristic features of operation of the high-voltage plasma generator of alternating current with rod electrodes working on a steam-air mixture. Current-voltage and volt-consumption characteristics, characteristic oscillograms of work, and results of research of influence of relationship of steam and air on electric arc parameters are represented. Researches were carried...
Summary form only given. Experiments with the aim of studying the dynamics of a ~mum thick radial metallic foil subject to the current from the MAGPEE generator (peak current of 1 MA in 250 ns) have been performed at Imperial College. After the start of the current pulse the foil is ohmically heated and then is driven by the JtimesB force in the axial direction, which is reasonably described by 0-D...
