This comprehensive text explores the latest techniques for producing a beam from any substance as well as from the dissociation of hydrogen, oxygen, nitrogen, and the halogens. Focusing on practical application in the laboratory, the author critically reviews over 800 references to compare the atomic and molecular beam formation theories with actual experiments. The book not only provides the basic expressions essential to beam design but also covers the construction of ovens, furnaces, and collimating arrays in metals, plastics, glass, and other materials.
