| basic vacuum practice varian: Synchrotron Radiation Sources - A Primer Herman Winick, 1995-02-28 Specialists in the technical components of a synchrotron light source are usually well versed in their field and in the associated technical literature. However, with the rapid and continuing growth of synchrotron radiation research, and with new facilities coming online and being authorized for design and construction around the world, there is a need for a reference book that describes the various technical components of a synchrotron light source in a manner that will be useful to those who lack specialized technical background, but who have responsibility for some part of the design, construction, operation or development of such a facility. This would include technicians, engineers and physicists who have technical background in related fields but no specific experience with a synchrotron light source, and also project managers, laboratory directors, and government officials involved with synchrotron light facilities.College level scientific or engineering training or the equivalent experience is assumed and appropriate mathematics is used throughout. However, the basic concepts in each chapter are given in less technical language and a glossary of terms as well as an index will make the book useful for those with less technical training or experience. |

| basic vacuum practice varian: The Electrostatic Accelerator Ragnar Hellborg, Harry J Whitlow, 2019-03-08 Electrostatic Accelerators have been at the forefront of modern technology since the development by Sir John Cockroft and Ernest Walton in 1932 of the first accelerator, which was the first to achieve nuclear transmutation and earned them the Nobel Prize in Physics in 1951. The applications of Cockroft and Walton's development have been far reaching, even into our kitchens where it is employed to generate the high voltage needed for the magnetron in microwave ovens. Other electrostatic accelerator related Nobel prize winning developments that have had a major socio-economic impact are; the electron microscope where the beams of electrons are produced by an electrostatic accelerator, X-rays and computer tomography (CT) scanners where the X-rays are produced using an electron accelerator and microelectronic technology where ion implantation is used to dope the semiconductor chips which form the basis of our computers, mobile phones and entertainment systems. Although the Electrostatic Accelerator field is over 90 years old, and only a handful of accelerators are used for their original purpose in nuclear physics, the field and the number of accelerators is growing more rapidly than ever. The objective of this book is to collect together the basic science and technology that underlies the Electrostatic Accelerator field so it can serve as a handbook, reference guide and textbook for accelerator engineers as well as students and researchers who work with Electrostatic Accelerators. |

| basic vacuum practice varian: Introduction to Vacuum Technology David M. Hata, 2008 The approach taken in this book is to approach vacuum systems from a pressure regime viewpoint. That is, after covering some basic chemistry, the first pressure regime covered is the rough vacuum regime. Within the study of rough vacuum systems, the following topics are covered: the gas load, the pumping mechanism, pressure measurement and vacuum system construction. The discussion of rough vacuum is then followed by the study of high-vacuum systems. The same topics are revisited, but this time from a high vacuum perspective. Once both rough vacuum and high vacuum systems are covered, then the topics of leak detection and residual gas analysis are introduced. This approach lends itself to laboratory experimentation. During the review of gas laws from chemistry, there are a number of experiments and demonstrations that can be performed to reinforce basic laws and concepts. Then, during the study of rough vacuum systems, pumpdown times can be calculated and pumpdowns performed in the laboratory. Likewise, during the study of high-vacuum systems, pumpdowns as well as other lab exercises, such as outgassing and residual gas analysis, can be conducted. Coverage of vacuum systems from a pressure regime viewpoint, rather than from a topical viewpoint. Focus on the fundamental science behind vacumm system components. This book is written for users of vacuum systems, especially the technicians that are responsible for maintaining them. |

| basic vacuum practice varian: Making Silicon Valley Christophe Lecuyer, 2007-08-24 In Making Silicon Valley, Christophe Lécuyer shows that the explosive growth of the personal computer industry in Silicon Valley was the culmination of decades of growth and innovation in the San Francisco-area electronics industry. Using the tools of science and technology studies, he explores the formation of Silicon Valley as an industrial district, from its beginnings as the home of a few radio enterprises that operated in the shadow of RCA and other East Coast firms through its establishment as a center of the electronics industry and a leading producer of power grid tubes, microwave tubes, and semiconductors. He traces the emergence of the innovative practices that made this growth possible by following key groups of engineers and entrepreneurs. He examines the forces outside Silicon Valley that shaped the industry—in particular the effect of military patronage and procurement on the growth of the industry and on the development of technologies—and considers the influence of Stanford University and other local institutions of higher learning. Lécuyer argues that Silicon Valley's emergence and its growth were made possible by the development of unique competencies in manufacturing, in product engineering, and in management. Entrepreneurs learned to integrate invention, design, manufacturing, and sales logistics, and they developed incentives to attract and retain a skilled and motivated workforce. The largest Silicon Valley firms—including Eitel-McCullough (Eimac), Litton Industries, Varian Associates, Fairchild Semiconductor, and Intel—dominated the American markets for advanced tubes and semiconductors and, because of their innovations in manufacturing, design, and management, served as models and incubators for other electronics ventures in the area. |

| basic vacuum practice varian: The Quantum Beat Fouad G. Major, 2013-03-09 One of the indicators of the level of technological development of a society has been, throughout history, the precision of clocks it was able to build. This book examines the physical principles underlying the workings of clocks--from the earliest mechanical clocks to the present-day sophisticated clocks based on the properties of individual atoms. Intended for non-specialists with some knowledge of physics or engineering,the book treats the material in a broad intuitive manner, with a minimum of mathematical formalism. The presentation covers a broad range of salient topics relevant to the measurement of frequency and time intervals. The main focus is on electronic time-keeping: clocks based on quartz crystal oscillators and, at greater length, atomic clocks based on quantum resonance in rubidium, cesium, and hydrogen atoms, and, more recently, mercury ions. The book treats the revolutionary changes that the optical laser has wrought on atomic standards through laser cooling and optical pumping, and it discusses the application of these clocks to global navigation--in particular Loran-C and the Global Positioning System. The book also touches on such topics as atomic resonance line shape, the relativistic Doppler effect and general notions of time, including the relativity of future and past, the clock paradox, the Sagnac effect and finally, time reversal symmetry. |
