Book Characterization of an Atmospheric Pressure Plasma Jet Using Optical Emission and Cavity Ringdown Spectroscopy

Download or read book Characterization of an Atmospheric Pressure Plasma Jet Using Optical Emission and Cavity Ringdown Spectroscopy written by Shane Moore Clark and published by . This book was released on 2018 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cold plasma is useful in numerous medical applications, largely because of the highly-reactive chemical species generated in the discharge. The hydroxyl radical (OH) is of these species and has significant biological importance. An atmospheric pressure plasma jet (APPJ) was constructed in the form of a plasma pencil, and relative and absolute measurements were made of OH in both its first excited ground state—OH(A) and OH(X), respectively—using optical emission spectroscopy and cavity ring-down spectroscopy (CRDS). The total number of OH radicals were found to be constant in the plume and within the range given by relative measurements made on similar devices in the literature.

Book Advanced Optical Diagnostics of Atmospheric Pressure Plasma

Download or read book Advanced Optical Diagnostics of Atmospheric Pressure Plasma written by Qing Xiong and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric-pressure plasma has been employed in various applications including bio-medicine, environmental pollution control, material processing. Diagnostic characterization of plasma sources is critical and indispensable for plasma control and achieving optimized treatment efficiency. In this chapter we will introduce several advanced optical techniques to visualize the detailed physical-and-chemical properties of atmospheric-pressure discharges. Non-invasive approaches of optical emission spectroscopy (OES), schlieren or shadowgraph, invasive methods of active laser spectroscopy including laser-induced fluorescence (LIF), laser or broadband absorption, cavity ring-down spectroscopy (CRDS), and laser scattering are illustrated. Basic plasma parameters of gas temperature, electron density and temperature, electric field strength, and reactive chemical gaseous species (O, H, N, OH, NO, O3, etc.) are able to be monitored. Comparisons and comments of these approaches are provided depending on diagnostic purposes.

Available in PDF, EPUB and Kindle. Book excerpt: Plasma as the fourth state of matter is an ionized gas consisting of both negative and positive ions, electrons, neutral atoms, radicals, and photons. In the last few decades, atmospheric-pressure plasmas have started to attract increasing attention from both scientists and industry due to a variety of potential applications. Because of increasing interest in the topic, the focus of this book is on providing engineers and scientists with a fundamental understanding of the physical and chemical properties of different atmospheric-pressure plasmas via plasma diagnostic techniques and their applications. The book has been organized into two parts. Part I focuses on the latest achievements in advanced diagnostics of different atmospheric-pressure plasmas. Part II deals with applications of different atmospheric-pressure plasmas.

Book The Modelling and Characterization of Dielectric Barrier Discharge Based Cold Plasma Jets

Download or read book The Modelling and Characterization of Dielectric Barrier Discharge Based Cold Plasma Jets written by G Divya Deepak and published by Cambridge Scholars Publishing. This book was released on 2020-01-15 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-equilibrium atmospheric pressure plasma jets (APPJs) are of intense interest in current low-temperature plasma research because of their immense potential for material processing and biomedical applications. Depending on the jet configuration and the electrical excitation, plasma characteristics including heat, charged particle, electric field, and chemically active species may differ significantly. Other important parameters of importance in these studies are the kind of utilized working gas and gas flow rate. This book presents the electrical characterization of DBD-based APPJs for three electrode arrangements: ring electrode, pin electrode and floating helix electrode configurations. The analysis presented here will serve to help in establishing an optimum range of operation for a cold plasma jet without arcing and without any physical damage to the electrodes. Furthermore, the experimental results provided in the book establish the significance of the type of working gas on the power consumption and on the jet length obtained. These developed cold DBD-based APPJs of larger lengths may be useful for diverse biological applications and surface treatments.

Book Optical Emission Diagnostics of a Non equilibrium Atmospheric Pressure Helium Plasma Jet in Ambient Air

Download or read book Optical Emission Diagnostics of a Non equilibrium Atmospheric Pressure Helium Plasma Jet in Ambient Air written by Eduardo Hernandez and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-thermal atmospheric pressure plasmas are increasingly attracting more attention from the scientific community for their potential use in surface treatment and biomedical applications. Even though considerable progress has been made, investigation of the species generated at close proximity (1 mm to ~100 nm) to a surface has not been addressed due to limitations of common optical techniques. A novel approach using Optical Emission Spectroscopy (OES) that can probe emissions over this distance away from the surface has been investigated. Additionally, the presence of high energy VUV photons was confirmed and these can play an important role in the propagation of plasma jets. By performing temporally resolved OES, it was determined that excitation of O, N, OH, NO and N2+ is predominantly due to collisions between He* and their precursors, whereas the N2 emissions are due to electron impact that produces electronically excited N2.
