Book Synopsis Near Discharge Cathode Assembly Plasma Potential Measurements in a 30-CM Nstar Type Ion Engine During Beam Extraction by : National Aeronautics and Space Administration (NASA)
Download or read book Near Discharge Cathode Assembly Plasma Potential Measurements in a 30-CM Nstar Type Ion Engine During Beam Extraction written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-24 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Floating emissive probe plasma potential data are presented over a two-dimensional array of locations in the near Discharge Cathode Assembly (DCA) region of a 30-cm diameter ring-cusp ion thruster. Discharge plasma data are presented with beam extraction at throttling conditions comparable to the NASA TH Levels 8, 12, and 15. The operating conditions of the Extended Life Test (ELT) of the Deep Space One (DS1) flight spare ion engine, where anomalous discharge keeper erosion occurred, were TH 8 and TH 12 consequently they are of specific interest in investigating discharge keeper erosion phenomena. The data do not validate the presence of a potential hill plasma structure downstream of the DCA, which has been proposed as a possible erosion mechanism. The data are comparable in magnitude to data taken by other researchers in ring-cusp electron-bombardment ion thrusters. The plasma potential structures are insensitive to thruster throttling level with a minimum as low as 14 V measured at the DCA exit plane and increasing gradually in the axial direction. A sharp increase in plasma potential to the bulk discharge value of 26 to 28 volts, roughly 10 mm radially from DCA centerline, was observed. Plasma potential measurements indicate a low-potential plume structure that is roughly 20 mm in diameter emanating from the discharge cathode that may be attributed to a free-standing plasma double layer.

Book Synopsis Introduction to Plasma Physics and Controlled Fusion by : Francis F. Chen
Download or read book Introduction to Plasma Physics and Controlled Fusion written by Francis F. Chen and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: TO THE SECOND EDITION In the nine years since this book was first written, rapid progress has been made scientifically in nuclear fusion, space physics, and nonlinear plasma theory. At the same time, the energy shortage on the one hand and the exploration of Jupiter and Saturn on the other have increased the national awareness of the important applications of plasma physics to energy production and to the understanding of our space environment. In magnetic confinement fusion, this period has seen the attainment 13 of a Lawson number nTE of 2 x 10 cm -3 sec in the Alcator tokamaks at MIT; neutral-beam heating of the PL T tokamak at Princeton to KTi = 6. 5 keV; increase of average ß to 3%-5% in tokamaks at Oak Ridge and General Atomic; and the stabilization of mirror-confined plasmas at Livermore, together with injection of ion current to near field-reversal conditions in the 2XIIß device. Invention of the tandem mirror has given magnetic confinement a new and exciting dimension. New ideas have emerged, such as the compact torus, surface-field devices, and the EßT mirror-torus hybrid, and some old ideas, such as the stellarator and the reversed-field pinch, have been revived. Radiofrequency heat ing has become a new star with its promise of dc current drive. Perhaps most importantly, great progress has been made in the understanding of the MHD behavior of toroidal plasmas: tearing modes, magnetic Vll Vlll islands, and disruptions.
Book Synopsis Inertial Electrostatic Confinement (IEC) Fusion by : George H. Miley
Download or read book Inertial Electrostatic Confinement (IEC) Fusion written by George H. Miley and published by Springer Science & Business Media. This book was released on 2013-12-12 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides readers with an introductory understanding of Inertial Electrostatic Confinement (IEC), a type of fusion meant to retain plasma using an electrostatic field. IEC provides a unique approach for plasma confinement, as it offers a number of spin-off applications, such as a small neutron source for Neutron Activity Analysis (NAA), that all work towards creating fusion power. The IEC has been identified in recent times as an ideal fusion power unit because of its ability to burn aneutronic fuels like p-B11 as a result of its non-Maxwellian plasma dominated by beam-like ions. This type of fusion also takes place in a simple mechanical structure small in size, which also contributes to its viability as a source of power. This book posits that the ability to study the physics of IEC in very small volume plasmas makes it possible to rapidly investigate a design to create a power-producing device on a much larger scale. Along with this hypothesis the book also includes a conceptual experiment proposed for demonstrating breakeven conditions for using p-B11 in a hydrogen plasma simulation. This book also: Offers an in-depth look, from introductory basics to experimental simulation, of Inertial Electrostatic Confinement, an emerging method for generating fusion power Discusses how the Inertial Electrostatic Confinement method can be applied to other applications besides fusion through theoretical experiments in the text Details the study of the physics of Inertial Electrostatic Confinement in small-volume plasmas and suggests that their rapid reproduction could lead to the creation of a large-scale power-producing device Perfect for researchers and students working with nuclear fusion, Inertial Electrostatic Confinement (IEC) Fusion: Fundamentals and Applications also offers the current experimental status of IEC research, details supporting theories in the field and introduces other potential applications that stem from IEC.

Book Synopsis Low Pressure Plasmas and Microstructuring Technology by : Gerhard Franz
Download or read book Low Pressure Plasmas and Microstructuring Technology written by Gerhard Franz and published by Springer Science & Business Media. This book was released on 2009-04-09 with total page 743 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last forty years, plasma supported processes have attracted ever - creasing interest, and now, all modern semiconductor devices undergo at least one plasma-involved processing step, starting from surface cleaning via coating to etching. In total, the range of the treated substrates covers some orders of magnitude: Trenches and linewidths of commercially available devices have - ready passed the boundary of 100 nm, decorative surface treatment will happen 2 in the mm range, and the upper limit is reached with surface protecting layers of windows which are coated with ?/4 layers against IR radiation. The rapid development of the semiconductor industry is inconceivable wi- outthegiantprogressintheplasmatechnology.Moore’slawisnotcarvedinto 1 stone, and not only the ITRS map is subject to change every ?ve years but also new branches develop and others mingle together. Moreover, the quality of conventional materials can be improved by plasma treatment:Cottonbecomesmorecrease-resistant,leathermoredurable,andthe shrinking of wool ?bers during the washing process can be signi?cantly reduced. To cut a long story short: More than 150 years after the discovery of the sputtering e?ect by Grove, plasma-based processes are about to spread out into new ?elds of research and application [1]—no wonder that the market for etching machines kept growing by an annual rate of 17 % up to the burst of the internet bubble, and it took only some years of recovery to continue the voyage [2].
Book Synopsis Ion Implantation: Equipment and Techniques by : H. Ryssel
Download or read book Ion Implantation: Equipment and Techniques written by H. Ryssel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fourth International Conference on Ion Implantation: Equipment and Tech niques was held at the Convention Center in Berchtesgaden, Bavaria, Germany, from September 13 to 17, 1982. It was attended by more than 200 participants from over 20 different countries. Severa1 series of conferences have dealt with the app1ication of ion implantation to semiconductors and other materials (Thousand Oaks, 1970; Garmisch-Partenkirchen, 1971; Osaka, 1974; Warwick, 1975; Bou1der, 1975; Budapest, 1978; and Albany, 1980). Another series of conferences has been devoted to implantation equipment and techniques (S- ford, 1977; Trento, 1978; and Kingston, 1980). This conference was the fourth in the 1atter series. Twe1ve invited papers and 55 contributed papers covered the areas of ion implantation equipment, measuring techniques, and app1ica tions of implantation to metals and semiconductors. A schoo1 on ion implantation was held in connection with the conference, and the 1ectures presented at this schoo1 were pub1ished as Vo1. 10 of the Springer Series in E1ectrophysics under the tit1e Ion Implantation Techniques (edited by H. Rysse1 and H. G1awischnig). During the conference, space was also provided for presentations and demonstrations by manufacturers of ion implantation equipment. Once again, this conference provided a forum for free discussion among implantation specia1ists in industry as we11 as research institutions. Espe cially effective in stimulating a free exchange of information was the daily get-together over free beer at the "Bier Adam". Many people contributed to the success of this conference.
