This document is the final technical report on the research activities carried out under AFOSR Grant F49620-03-1-0325. Here we present our research results, which took place in the last three years and a half. Particularly, during the later period of performance the focus of our activities was on carrying out diagnostics on plasma devices based on new approaches that use high voltage narrow pulses to ignite the plasma. These novel approaches allow for the generation of non-thermal high-pressure discharges that can be used as radiation sources and for biomedical applications.

Download Mechanisms of Ionizational Nonequilibrium in Air Plasmas Book in PDF, Epub and Kindle
The goal of this MURI program was to discover physical mechanisms for significantly reducing the power budget required to create and sustain large volume atmospheric air plasmas at temperature below 2000K with electron number densities of the order of 10 13 cm -3. The Stanford consortium Experimentally demonstrated the generation of over 10 12 electrons/cm 3 in atmospheric pressure air at 2000K, with an average power of 12 W/cm 3, i.e. 250 times smaller than a DC discharge at 10 12/cm3.

Download Creation and Measurement of Air Plasmas Book in PDF, Epub and Kindle
The parent program focuses on minimization of power budget for the efficient creation of large volume, atmospheric pressure air plasmas, with minimum electron density of 10(exp 13)/cu cm and heavy species translational temperature not exceeding 2000 K. Since a thermal plasma with 10(exp 13)/cu cm electron density necessitates a heavy species temperature of approximately 4200 K. the stated program goals inherently define a nonequilibrium plasma. OSU's approach for attaining the program goals is two-pronged based on: (1) Creation of a low translational temperature, highly vibrationally excited environment in which the rates of principal electron loss channels are reduced by orders of magnitude. (2) Efficient electron production by means of an electron beam and/or application of a short pulse. high E/n electric field.

Download Nonequilibrium Air Plasma Chemistry Book in PDF, Epub and Kindle
This AASERT program has enabled the training and support of four graduate students (Richard Gessman, PhD. 1999, Edward Wahl, Ph. D. 2000, Kate Snyder, Ph. D. 2002, expected, and Jonathan Flad, Ph. D. 2002, expected) in the framework of the Air Plasma Ramparts MURI program entitled I Mechanism of ionizational Nonequilibrium in Air Plasmas. The goal of the Air Plasma Ramparts program is to investigate energy efficient methods for creating and sustaining large volume atmospheric air plasmas with electron number densities greater than 10(exp 13)/cu cm that can be employed to shield aircrafts or other sensitive components from electromagnetic radiation. Our approach at Stanford University has been to enhance ionizational nonequilibrium by means of applied electrical discharges. Our investigations have focused on two types of discharge, namely direct-current (dc) and repetitively pulsed discharges. The AASERT students involved with this program have provided support in the study of the dc discharges in air and nitrogen plasmas. The outcome of this work is presented.

Download Cold Plasma Book in PDF, Epub and Kindle
Non-equilibrium plasma (or low-temperature plasma, LTP) offers a chemically rich medium without the need for high power and elevated temperatures. This unique characteristic has made LTP very useful for various industrial and biomedical applications where thermal effects are not desirable. In addition, the relative simplicity of the design of sources capable of generating non-equilibrium plasma at atmospheric pressure makes LTP a very attractive technology that can accomplish the same or better results than much more complex and expensive approaches. This book describes various low-temperature plasma sources and some of their environmental and biomedical applications. The plasma sources covered in this book include low-temperature plasma jets which are novel devices that can launch low-power, low-temperature plasma plumes in ambient air. These plasma plumes can accurately and reliably be aimed at a surface to be treated or at a biological target such as cells and tissues. The application of these plasma jets in medicine, including in cancer therapy, are thoroughly discussed in this book. The contents of this book will appeal to engineers, medical experts, academics, and students who work with plasma technology.

This document is the final report on the research activities carried out under AFOSR Grant F49620-00-1-0168. It describes the research results and the various events, which took place during the period of this research program. The focus of our activities is the investigation of the properties of a large volume, non-thermal, atmospheric pressure plasma generated by the "Resistive Barrier Discharge". The biological applications of this discharge have also been investigated. These include the study of the germicidal effects as well as the effects of the plasma on the biochemical pathways of bacteria.
