Available in PDF, EPUB and Kindle. Book excerpt: The High Performance Hall System (HPHS) program supports the development and flight qualification of a 4.5 kW electric propulsion system that includes the SPT-140 Hall thruster. The Air Force Research Laboratory (AFRL) and International Space Technology, Inc. (ISTI) are co-funding the HPHS program which is being conducted by a team led by Atlantic Research Corporation (ARC). The team includes ISTI, Experimental Design Bureau Fakel (Fakel), and Space Systems/Loral (S/SL). The Research Institute of Applied Mechanics and Electrodynamics (RIAME) also provided support for this project. The SPT-140 is being designed, developed, manufactured, and tested by Fakel in Kaliningrad, Russia, where extensive performance testing and advanced development have been performed. In addition to the testing in Russia, a suite of experiments on the development model and the qualification model thrusters, sponsored by the US Government, has occurred during 1999 and 2000 and is scheduled to continue through 2000. These experiments include thruster performance, plume characterization electromagnetic compatibility, and life characterization. This paper presents the status of government testing of the SPT-140 in the United States.

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 Photoabsorption Photoionization and Photoelectron Spectroscopy written by Joseph Berkowitz and published by Academic Press. This book was released on 2012-12-02 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photoabsorption, Photoionization, and Photoelectron Spectroscopy explores photoabsorption processes involving individual, isolated molecules in the wavelength or photon energy range from the ionization thresholds of molecules (usually in the vacuum ultraviolet region) through the soft and hard X-ray region and beyond the ""K edge."" The interaction between electromagnetic radiation and isolated molecules based on photoabsorption, photoionization, and photoelectron spectroscopy studies is described, along with the techniques for measurement of total and partial cross sections. This book is comprised of eight chapters and examines the decomposition of molecules and molecular ions as well as mildly excited (valence shell excitation) and highly excited (inner shell excitation) molecules. After providing a general theoretical background, it discusses certain classes of atoms and molecules and considers electromagnetic interactions with gases. The following chapters focus on photoabsorption below the first ionization limit; quasi-discrete states above the first ionization potential; and the ionization continuum. Total photoabsorption and photoionization cross sections for selected molecules are also considered, and the angular distribution of photoelectrons is analyzed. The various measurement techniques are described in the last chapter. This monograph will be of interest to radiation chemists, radiation physicists, photochemists, mass spectrometrists, and perhaps radiation biologists.

Download or read book Inner Speech written by Peter Langland-Hassan and published by Oxford University Press, USA. This book was released on 2018-10-18 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inner speech lies at the chaotic intersection of several difficult questions in contemporary philosophy and psychology. On the one hand, these episodes are private mental events. On the other, they resemble speech acts of the sort used in interpersonal communication. Inner speech episodes seem to constitute or express sophisticated trains of conceptual thought but, at the same time, they are motoric in nature and draw on sensorimotor mechanisms for speech production and perception more generally. By using inner speech, we seem to both regulate our bodily actions and gain a unique kind of access to our own beliefs and desires. Inner Speech: New Voices explores this familiar and yet mysterious element of our daily lives, bringing together contributions from leading philosophers, psychologists, and neuroscientists. In response to renewed interest in the general connections between thought, language, and consciousness, these leading thinkers develop a number of important new theories, raise questions about the nature of inner speech and its cognitive functions, and debate the current controversies surrounding the 'little voice in the head.'
