PREFACE
The plan of this book is to give a general introduction to velocity-modulation tubes and their mode of operation in such a form as to be readily intelligible to anyone with a reasonably adequate knowledge of pre-1939 radio technique. The essential minimum of information on resonant cavities is included, and there is some information on heavy current electron beams. The major part of the work is, however, the general theory of the interchange of energy between field and beam given in Chapter 3, together with the application of this theory to various types of V.M. tube in Chapters 5, 6, 7 and 8.
It was not intended that this book should be a formal text-book with full and critical documentation, but rather that it should give a personal account of a division of research which is still progressing rapidly. The free interchange of information between British and American government and commercial tube laboratories has, however, meant that a large fund of common knowledge has been built up, and it is therefore hoped that the work is in general agreement with the views of other researchers in the same field.
An attempt has been made to build up the theory from simple postulates by successive refinements so that physical facts dominate mathematical considerations, and a realistic picture of the way in which a physical theory is arrived at can be obtained.
Little has been said about the uses to which V.M. valves are put or about measurements on them. These matters are dealt with elsewhere and space did not permit their inclusion. The manuscript was completed in April 1946, before the Radiolocation Conference of the I.E.E., but references to most of the work published since that date have been included, in addition to an appendix on the travelling wave tube. Where an author’s name is given without a reference, unpublished work is implied. I have tried to make as little use of such work as possible, but where it has been unavoidable, I have included the author’s name as some acknowledgement.
