Production of Atmospheric Pressure Plasma with Pulsed Power Technologies

High Voltage Pulsed Atmospheric Pressure Helium Plasma Jet

Non-equilibrium cold plasma jets generated under atmospheric pressure by means of high voltage pulsed power generator are extended up to a few centimeters long in the surrounding air. The generator is consisting of a negative dc source, a Blumlein-type pulse-forming network (E-PFN), and a dynamic spark gap switch. The plasma jet generated by the device using helium as the operating gas depends ...

Plasma Pulsed Power Generation

Design and implementation of high voltage square wave power source with variable DC-offset and study its effect on atmospheric-pressure plasma

Nowadays high-voltage power sources is used in different areas such as generation of atmospheric-pressure plasma. Different voltage waveforms affect the plasma generation and its quality. In this paper a new high voltage square wave with DC-offset power source is presented to study the different parameters on plasma generation and propagation. The proposed converter which is based on power semi...

Molecular Effects of Atmospheric Pressure Plasma Jet on the Double-Stranded DNA

Introduction The aim of this study was toinvestigate the sterilization potential of atmospheric pressure plasma jet (APPJ) and interactions of this technology with double-stranded DNA using the polymerase chain reaction (PCR) and single-strand conformation polymorphism (SSCP) techniques. Materials and Methods The plasma jet was produced through a high voltage sinusoidal power supplyusing a mixt...

Atmospheric Pressure Plasma Cleaning of Contamination Surfaces

Technical Description of the Work Decommissioning of transuranic waste (TRU) into low-level radioactive waste (LLW) represents the largest cleanup cost associated with the nuclear weapons complex. This work is directed towards developing a low-cost plasma technology capable of converting TRU into LLW, based upon highly selective plasma etching of plutonium and other actinides from contaminated ...
