Written by an internationally recognized as an expert on the subject of microwave (MW) tubes, this book presents and describes the many types of microwave tubes, and despite competition from solid-state devices (those using GaN, SiC, et cetera), which continue to be used widely and find new applications in defense, communications, medical, and industrial drying. Helix traveling wave tubes (TWTs), as well as coupled cavity TWTs are covered. Klystrons, and how they work, are described, along with the physics behind it and examples of devices and their uses. Vacuum electron devices are explained in detail and examines the harsh environment that must exist in tubes if they are to operate properly. The secondary emission process and its role in the operation of crossed-field devices is also discussed. The design of collectors for linear-beam tubes, including power dissipation and power recovery, are explored. Discussions of important noise sources and techniques that can be used to minimize their effects are also included. Presented in full color, this book contains a balance of practical and theoretical material so that those new to microwave tubes as well as experienced microwave tube technicians, engineers, and managers can benefit from its use.

The purpose of this book is to provide graduate students, professional engineers, military officers, and weapons-systems planners with a comprehensive grounding in the technology, evolution, functions, costs, impacts on society, utility, and limi tations of modern strategic weapons systems. Since the subject is often left to the specialists, this work should introduce the general reader to the fundamentals of such systems in an informed manner. Nowadays the intense interaction of means and ends sym bolized by strategic weapons has stimulated a changing dis cipline in which new missile systems and the intricate logic of nuclear force and counterforce hold the stage alongside the truths of conflict, alliances, fears, games, and subtle gains and losses. Many readers with new personal interest or public responsibility in this complex field will require an overall guide to it. This book will not prepare the reader to become an expert in the vast subject of strategic weapons systems. It will, however, enable him to understand, evaluate, and form reasonable opinions about these systems, their capabilities and effective ness. The subject is dealt with more from the viewpoint of the user (investor) rather than the architect (systems engineer) and builder (design engineer). While the user will be concerned with both political as well as technical options which may be available to solve a problem, the systems and design engineers are concerned with analyzing and building technological weapons devices once their requirements are generally known.

Astronomy and Astrophysics Abstracts aims to present a comprehensive documen tation ofthe literatme concerning all aspects of astronomy, astrophysics, and their border fields. lt is devoted to the recording, summarizing, and indexing of the relevant publications throughout the world. Astronomy and Astrophysics Abstracts is prepared by a special department of the Astronomisches Rechen-Institut under the auspices of the International Astronomical Union. Volume 40 records literatme published in 1985 and received before February 15, 1986. Some older documents which we received late and which arenot surveyed in earlier volumes are included too. We acknowledge with thanks contributions of our colleagues all over the world. We also express our gratitude to all organiza tions, observatories, and publishers which provide us with complimentary copies of their publications. Starting with Volume 33, all the recording, correction, and data processing work was dorre by means of computers. The recording was dorre by om technical staff members Ms. Helga Ballmann, Ms. Mona El-Choura (t), Ms. Monika Kohl, Ms. Sylvia Matyssek. Ms. Karirr Burkhardt, Ms. Susanne Schlötelbmg, Mr. Mar tin Schlötelburg, and Mr. Stefan Wagner supported om task by careful proof reading. lt is a pleasure to thank them all for their encomagement.
