Download or read book High Average Power Broadband Electron Bombarded Semiconductor EBS Amplifier written by Bruce Bell and published by . This book was released on 1979 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the current reporting period the analysis phase of the program was completed, which included the diode design study, thermal analysis and output matching circuit analysis. Based on the analysis, modifications are currently being made to two existing diode mask sets. Diode fabrication will not continue until the mask sets are completed. Similarly, device fabrication will not continue until additional testing has been completed on Contract no. F30602-78-C-0247, whose goal is to develop a 500 W peak, 20% duty amplifier for JTIDS in conjunction with this program. It is planned that device fabrication will resume by May, which will allow sufficient time for completion of the program on schedule.

Available in PDF, EPUB and Kindle. Book excerpt: This paper describes a high-powered radio-frequency amplifier being developed for communications jamming and other applications in the HF band. It is intended to put out 10- 100 kW over the 2-30 MHz band without tuning or filters. Its principle of operation is based on the current flowing through reverse-biased diodes due to the creation of electron-hole pairs by high-energy electrons passing through the junction regions. A set of 100 - 1000 diodes are combined in an array to make an amplifier with 10 - 100 kW of output power. This amplifier has the advantages of high power, small size, high gain, and high linearity. Communications Countermeasures.

Download or read book The Electron Beam Semiconductor EBS Amplifier written by Robert M. True and published by . This book was released on 1980 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Electron Beam Semiconductor (EBS) concept has existed for three decades; but only within the last decade has an active, well-defined program been underway to develop devices that can operate as high-power radio frequency(RF) amplifiers, fast risetime switches, and current and voltage pulse amplifiers. This report discusses the test procedures, data and results of reliability testing of RF and video pulse EBS amplifiers at Electronics Research and Development Command (ERADCOM), Fort Monmouth, New Jersey. Also, the experimental analysis of the series-connected diode EBS device is described in detail. Finally, the report concludes with a discussion of the state-of-the-art of EBS and future trends of the technology. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: In today's world, the range of technologies with the potential to threaten the security of U.S. military forces is extremely broad. These include developments in explosive materials, sensors, control systems, robotics, satellite systems, and computing power, to name just a few. Such technologies have not only enhanced the capabilities of U.S. military forces, but also offer enhanced offensive capabilities to potential adversaries - either directly through the development of more sophisticated weapons, or more indirectly through opportunities for interrupting the function of defensive U.S. military systems. Passive and active electro-optical (EO) sensing technologies are prime examples. Laser Radar considers the potential of active EO technologies to create surprise; i.e., systems that use a source of visible or infrared light to interrogate a target in combination with sensitive detectors and processors to analyze the returned light. The addition of an interrogating light source to the system adds rich new phenomenologies that enable new capabilities to be explored. This report evaluates the fundamental, physical limits to active EO sensor technologies with potential military utility; identifies key technologies that may help overcome the impediments within a 5-10 year timeframe; considers the pros and cons of implementing each existing or emerging technology; and evaluates the potential uses of active EO sensing technologies, including 3D mapping and multi-discriminate laser radar technologies.

Book excerpt: This completely updated and revised second edition of Surface Analysis: The Principal Techniques, deals with the characterisation and understanding of the outer layers of substrates, how they react, look and function which are all of interest to surface scientists. Within this comprehensive text, experts in each analysis area introduce the theory and practice of the principal techniques that have shown themselves to be effective in both basic research and in applied surface analysis. Examples of analysis are provided to facilitate the understanding of this topic and to show readers how they can overcome problems within this area of study.

This book was released on 2013-11-11 with total page 679 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has evolved by processes of selection and expansion from its predecessor, Practical Scanning Electron Microscopy (PSEM), published by Plenum Press in 1975. The interaction of the authors with students at the Short Course on Scanning Electron Microscopy and X-Ray Microanalysis held annually at Lehigh University has helped greatly in developing this textbook. The material has been chosen to provide a student with a general introduction to the techniques of scanning electron microscopy and x-ray microanalysis suitable for application in such fields as biology, geology, solid state physics, and materials science. Following the format of PSEM, this book gives the student a basic knowledge of (1) the user-controlled functions of the electron optics of the scanning electron microscope and electron microprobe, (2) the characteristics of electron-beam-sample inter actions, (3) image formation and interpretation, (4) x-ray spectrometry, and (5) quantitative x-ray microanalysis. Each of these topics has been updated and in most cases expanded over the material presented in PSEM in order to give the reader sufficient coverage to understand these topics and apply the information in the laboratory. Throughout the text, we have attempted to emphasize practical aspects of the techniques, describing those instru ment parameters which the microscopist can and must manipulate to obtain optimum information from the specimen. Certain areas in particular have been expanded in response to their increasing importance in the SEM field. Thus energy-dispersive x-ray spectrometry, which has undergone a tremendous surge in growth, is treated in substantial detail.
