The purpose of this text is to introduce engineering and science students to the basic underlying physics and chemistry concepts that form the foundation of plasma science and engineering. It is an accessible primer directed primarily at those students who, like the general public, simply do not understand exactly what a plasma or gas discharge is nor do they even necessarily have the fundamental background in statistical thermodynamics, gas dynamics, fluid dynamics, or solid state physics to effectively understand many plasma and gas discharge principles. At the conclusion of this text, the reader should understand what an ion is, how they move, the equations we use to describe these basic concepts, and how they link to the aforementioned topics of plasmas and gas discharges. This book is focused on specific concepts that are important to non-equilibrium, low temperature gas discharges. These discharges fi nd wide applicability today and are of significant interest to the scientifi c and engineering communities.

Gas discharges and non-equilibrium low-temperature plasmas form the basis for most plasma technologies. This book introduces engineering and science students to the basic underlying physics and chemistry concepts that form the foundation of plasma science and engineering. It is an accessible primer directed primarily at those students who are unaware what a plasma or gas discharge is, nor have fundamental backgrounds in statistical thermodynamics, gas dynamics, fluid dynamics, or solid-state physics to effectively understand many plasma and gas discharge principles. The second edition covers additional topics such as gas breakdown leading to plasma initiation and the formation of sheaths, and discusses these within the context of a basic description of the most common plasma type, a dc glow discharge. This text is suitable for upper level undergraduate students, graduate students, and young researchers in physics, chemistry, chemical engineering, electrical engineering, and mechanical engineering with interest in plasma science and engineering.

Over the last decade, scientific and engineering interests have been shifting from conventional ion mobility spectrometry (IMS) to field asymmetric waveform ion mobility spectrometry (FAIMS). Differential Ion Mobility Spectrometry: Nonlinear Ion Transport and Fundamentals of FAIMS explores this new analytical technology that separates and characterizes ions by the difference between their mobility in gases at high and low electric fields. It also covers the novel topics of higher-order differential IMS and IMS with alignment of dipole direction. The book relates the fundamentals of FAIMS and other nonlinear IMS methods to the physics of gas-phase ion transport. It begins with the basics of ion diffusion and mobility in gases, covering the main attributes of conventional IMS that are relevant to all IMS approaches. Building on this foundation, the author reviews diverse high-field transport phenomena that underlie differential IMS. He discusses the conceptual implementation and first-principles optimization of FAIMS as a filtering technique, emphasizing the dependence of FAIMS performance metrics on instrumental parameters and properties of ion species. He also explores ion reactions in FAIMS caused by field heating and the effects of inhomogeneous electric field in curved FAIMS gaps. Written by an accomplished scientist in the field, this state-of-the-art book supplies the foundation to understand the new technology of nonlinear IMS methods.

Transport phenomena in plasmas are the relatively slow processes of particle momentum and energy transport systems in a state of mechanical equilibrium. In contrast to neutral gases, these phenomena in plasmas are greatly influenced by self-consistent fields, in particular electric fields. These can produce particle and energy fluxes, in addition t

Projectile fragmentation followed by in-flight separation produces radioactive nuclear beams (RNBs) at energies of ~100 MeV/u and corresponding velocities of up to half the speed of light at the National Superconducting Cyclotron Laboratory (NSCL). In order to use nuclei produced at these high energies in low-energy experiments, the beams must be slowed to kinetic energies of ~1 eV. Collection and thermalization of rare ions in a gas cell using static electric fields was first demonstrated at the NSCL. Other gas cells have used radio frequency (RF) electric fields coupled to a static drift field to transport the ions through the helium buffer gas instead of a simple electrostatic field . A new so-called ``ion surfing'' method for ion transport was proposed by Bollen and demonstrated experimentally in this work through detailed measurements with thermal rubidium and potassium ions. These elements were found to be efficiently transported over distances of up to 40 cm in helium gas pressures ranging from 40 to 200 mbar. Transport speeds as high as 75 m/s and 60 m/s were reached for rubidium and potassium ions, respectively, at a gas pressure of 80 mbar. Measured ion speed and transport efficiencies were found to be in good agreement with the results of detailed ion transport simulations. This work validates ``ion surfing'' as a viable method to transport thermal ions in buffer gas and documents its preparation for use in next-generation beam thermalization devices. -- Abstract.

Radial transport of ions during co- and counter-neutral beam heating in the PLT tokamak has been studied, using molybdenum and scandium ions as tracer elements. The time evolution of the radial profiles of several ionization stages of both elements, injected by laser blowoff during the neutral beam heating, were measured under three significantly different beam-plasma combinations. No noticeable differences in the radial profiles attributable to the beam direction were observed. However, a given injected amount resulted in considerably larger interior concentrations of the tracer element in the counter-beam heating cases, suggesting larger penetration of the plasma periphery. Computer simulation with the MIST code suggests a net inward drift of the order 103 cm/sec superposed to a diffusion coefficient of the order 104 cm2/sec for both scandium and molybdenum ions. Injection of larger amounts of the tracer element, sufficient to cause measurable central electron temperature changes, resulted in dramatic changes in ion-state distributions, making some appear peaked in the center while others disappeared. This effect could be produced with both co- and counter-beam heating, but with lesser amounts in the latter case. It is interpreted as rearrangement of the ionization balance, rather than any preferential accumulation of the injected element.
