Download or read book Field Evaporation Ion Source with Possible Application to Electrostatic Propulsion written by Victor G. Weizer and published by . This book was released on 1971 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field evaporation of solid metal electrodes has been proposed as an ion source for an electrostatic propulsion device. The chief advantage over existing ion sources is the prospect of 100 percent fuel utilization efficiency. This advantage arises as a result of the elimination of the need for a gaseous precursor state for propellant ionization. The attainment of required high surface field strengths is achieved through field-induced extrusion of the electrode geometry at elevated temperatures. Contributions of both surface and bulk transport mechanisms are taken into account.

This book was released on 2003-02-06 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Expansion of micro-technology applications and rapid advances in nano-science have generated considerable interest by the Air Force in how these developments will affect the nature of warfare and how it could exploit these trends. The report notes four principal themes emerging from the current technological trends: increased information capability, miniaturization, new materials, and increased functionality. Recommendations about Air Force roles in micro- and nanotechnology research are presented including those areas in which the Air Force should take the lead. The report also provides a number of technical and policy findings and recommendations that are critical for effective development of the Air Force's micro- and nano-science and technology program

Download or read book MEMS and Microstructures in Aerospace Applications written by Robert Osiander and published by CRC Press. This book was released on 2018-10-03 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: The promise of MEMS for aerospace applications has been germinating for years, and current advances bring the field to the very cusp of fruition. Reliability is chief among the challenges limiting the deployment of MEMS technologies in space, as the requirement of zero failure during the mission is quite stringent for this burgeoning field. MEMS and Microstructures in Aerospace Applications provides all the necessary tools to overcome these obstacles and take MEMS from the lab bench to beyond the exosphere. The book begins with an overview of MEMS development and provides several demonstrations of past and current examples of MEMS in space. From this platform, the discussion builds to fabrication technologies; the effect of space environmental factors on MEMS devices; and micro technologies for space systems, instrumentation, communications, thermal control, guidance navigation and control, and propulsion. Subsequent chapters explore factors common to all of the described systems, such as MEMS packaging, handling and contamination control, material selection for specific applications, reliability practices for design and application, and assurance practices. Edited and contributed by an outstanding team of leading experts from industry, academia, and national laboratories, MEMS and Microstructures in Aerospace Applications illuminates the path toward qualifying and integrating MEMS devices and instruments into future space missions and developing innovative satellite systems.

Written by the leading research scientists, the second edition of the Handbook of Charged Particle Optics is a complete guide to understanding, designing, and using high resolution probe instrumentation.
Download or read book Fundamentals of Electric Propulsion written by Dan M. Goebel and published by John Wiley & Sons. This book was released on 2008-12-22 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout most of the twentieth century, electric propulsion was considered the technology of the future. Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance. They then go on to present detailed explanations of: Thruster principles Ion thruster plasma generators and accelerator grids Hollow cathodes Hall thrusters Ion and Hall thruster plumes Flight ion and Hall thrusters Based largely on research and development performed at the Jet Propulsion Laboratory (JPL) and complemented with scores of tables, figures, homework problems, and references, Fundamentals of Electric Propulsion: Ion and Hall Thrusters is an indispensable textbook for advanced undergraduate and graduate students who are preparing to enter the aerospace industry. It also serves as an equally valuable resource for professional engineers already at work in the field.
Download or read book High Resolution Focused Ion Beams FIB and its Applications written by Jon Orloff and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, we have attempted to produce a reference on high resolution focused ion beams (FIBs) that will be useful for both the user and the designer of FIB instrumentation. We have included a mix of theory and applications that seemed most useful to us. The field of FIBs has advanced rapidly since the application of the first field emission ion sources in the early 1970s. The development of the liquid metal ion source (LMIS) in the late 1960s and early 1970s and its application for FIBs in the late 1970s have resulted in a powerful tool for research and for industry. There have been hundreds of papers written on many aspects of LMIS and FIBs, and a useful and informative book on these subjects was published in 1991 by Phil Prewett and Grame Mair. Because there have been so many new applications and uses found for FIBs in the last ten years we felt that it was time for another book on the subject.
