Market: Students and researchers in space and high-vacuum technology and materials science. This handbook was originally prepared so that workers would not have to consult a great many sources to learn what procedures and materials were used to construct tubes and other evacuated devices. Even now, as space and high-vacuum research are yielding new information daily, much of the subject matter in this seminal work, such as properties of materials, are as cogent as they were in 1964 when the book was first published.
