Hamilton D.R., Knipp J.K., Kuper J.B.H. Klystrons and Microwave Triodes

New York: McGraw-Hill, 1948. — 533 p. — (MIT Radiation Laboratory Series. Volume 7)This volume of the Radiation Laboratory Series attempts to cover the basic principles underlying the operation of klystrons and planar grid tubes as oscillators and amplifiers. It has been the desire of the authors to present the technical and theoretical aspects of this field as completely and as rigorously as possible, even though this meant the exclusion of a great deal of descriptive material, and has certainly added to the difficulty of a first reading. Nevertheless it was felt that the greatest need for a book on this subject at the present time was for one from which the fundamental principles for the design and understanding of microwave vacuum tubes could be obtained. No attempt has been made to describe how a vacuum tube is actually constructed. Rather the emphasis has been placed on presenting the fundamental material which the tube designer or tube user must have at his command.
Because the radio-frequency work of the Radiation Laboratory was concentrated almost entirely in the frequency region above 3000 Mc/sec, this book naturally tends to emphasize the operation of tubes in that region. However the basic principles are the same at lower frequencies although as a general rule the electrical and mechanical requirements become more difficult to attain as higher frequencies are approached. Certainly it is the authors’ hope that this is a book on the principles of operation of particular types of tubes, and not a treatise on the generation of oscillations in a particular frequency band.
