Book excerpt: The microwave ammonia monitor is a self contained (the vacuum pump is external) microwave rotational spectrometer that selectively detects and monitors ammonia vapor in air. A solid-state oscillator is used as the microwave source and a microwave cavity made from waveguide provides a chamber for the sample analysis. The air sample is continuously flowed through the waveguide cavity so that changes in the trace concentration of ammonia in air can be determined. The principle of operation of the microwave ammonia monitor is based on the absorption of microwave radiation by a vibration-rotation quantum transition of the ammonia molecule. Ammonia absorbs microwave radiation in a very narrow frequency range with its peak at 23,870.18 MHz. The microwave source is electronically controlled to oscillate only at this frequency and to provide a very stable output power. Thus, even a very small amount of microwave power that is absorbed by the ammonia gas is detectable and no other gas in the air sample is known to absorb any microwave radiation within the frequency output band of the oscillator. The specifications, operation, and maintenance procedures are described. Also a parts list and engineering drawings are included. (WHK).

Download or read book Introduction to Quantum Metrology written by Waldemar Nawrocki and published by Springer. This book was released on 2015-03-24 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the theory of quantum effects used in metrology and results of the author’s own research in the field of quantum electronics. The book provides also quantum measurement standards used in many branches of metrology for electrical quantities, mass, length, time and frequency. This book represents the first comprehensive survey of quantum metrology problems. As a scientific survey, it propagates a new approach to metrology with more emphasis on its connection with physics. This is of importance for the constantly developing technologies and nanotechnologies in particular. Providing a presentation of practical applications of the effects used in quantum metrology for the construction of quantum standards and sensitive electronic components, the book is useful for a wide audience of physicists and metrologists in the broad sense of both terms. In 2014 a new system of units, the so called Quantum SI, is introduced. This book helps to understand and approve the new system to both technology and academic community.

Download or read book Handbook of Chemical Vapor Deposition written by Hugh O. Pierson and published by William Andrew. This book was released on 1999-09-01 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: Turn to this new second edition for an understanding of the latest advances in the chemical vapor deposition (CVD) process. CVD technology has recently grown at a rapid rate, and the number and scope of its applications and their impact on the market have increased considerably. The market is now estimated to be at least double that of a mere seven years ago when the first edition of this book was published. The second edition is an update with a considerably expanded and revised scope. Plasma CVD and metallo-organic CVD are two major factors in this rapid growth. Readers will find the latest data on both processes in this volume. Likewise, the book explains the growing importance of CVD in production of semiconductor and related applications.

Download or read book Fundamentals of Silicon Carbide Technology written by Tsunenobu Kimoto and published by John Wiley & Sons. This book was released on 2014-11-24 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive introduction and up-to-date reference to SiC power semiconductor devices covering topics from material properties to applications Based on a number of breakthroughs in SiC material science and fabrication technology in the 1980s and 1990s, the first SiC Schottky barrier diodes (SBDs) were released as commercial products in 2001. The SiC SBD market has grown significantly since that time, and SBDs are now used in a variety of power systems, particularly switch-mode power supplies and motor controls. SiC power MOSFETs entered commercial production in 2011, providing rugged, high-efficiency switches for high-frequency power systems. In this wide-ranging book, the authors draw on their considerable experience to present both an introduction to SiC materials, devices, and applications and an in-depth reference for scientists and engineers working in this fast-moving field. Fundamentals of Silicon Carbide Technology covers basic properties of SiC materials, processing technology, theory and analysis of practical devices, and an overview of the most important systems applications. Specifically included are: A complete discussion of SiC material properties, bulk crystal growth, epitaxial growth, device fabrication technology, and characterization techniques. Device physics and operating equations for Schottky diodes, pin diodes, JBS/MPS diodes, JFETs, MOSFETs, BJTs, IGBTs, and thyristors. A survey of power electronics applications, including switch-mode power supplies, motor drives, power converters for electric vehicles, and converters for renewable energy sources. Coverage of special applications, including microwave devices, high-temperature electronics, and rugged sensors. Fully illustrated throughout, the text is written by recognized experts with over 45 years of combined experience in SiC research and development. This book is intended for graduate students and researchers in crystal growth, material science, and semiconductor device technology. The book is also useful for design engineers, application engineers, and product managers in areas such as power supplies, converter and inverter design, electric vehicle technology, high-temperature electronics, sensors, and smart grid technology.
