Book Description
This volume contains most of the invited and contributed papers presented at the second international conference devoted to the general topic "Vibrations at Surfaces" and which took place from 10 to 12 September 1980 at the Facu1tes Notre-Dame de 1a Paix in Namur, Belgium. The conference was organized to review the large amount of information gathered in this field over the late seventies as a result of th~ rapid improvements and dissemination of surface spectroscopic technique such a electron energy loss, infrared and Raman surface spectroscopies. Much time was devoted to Raman spectroscopy of adsorbed mo1e 'cu1es. After several years of vivid debate over the causes of the observed large enhancement of Raman cross section, a clearer pic ture emerges from the papers presented here: the actual value of the enhancement factor does depend in a complicated manner on long range surface roughness, atomic-scale roughness and the dielectric properties of the substrate as well as on the electronic structure of the molecule in its adsorbed state. Less controversial are the results obtained with electron energy loss spectroscopy (EELS) and several sessions of the con ference were devoted to the approach. As witnessed by the growing number of laboratories using the technique, EELS is now a mature spectroscopic tool for the characterization and analysis of the chemisorption bond.

Book Description
1965 Transactions of the Third International Vacuum Congress, Volume 2, Part I documents the proceedings on the Third International Vacuum Congress held in Stuttgart, Germany on June 28-July 2, 1965. This compilation is divided into four sessions. Session 1 focuses on evaporation and thin films, while Session 2 deals with the flow of gases. The components and materials of orthodox vacuum pumps are covered in Session 3. The last session concentrates on pressure measurement and leak detection. The topics discussed include developments in the vacuum deposition of electronic film circuits; bulk sublimation of titanium; transmission probability determination with directed mass motion and with mean free path considerations; measuring the density and direction of gas molecular flow using an ionization detector; and porous metal isolation traps and cryosorbents in vacuum technique. The factors influencing the performance and design of water-cooled condensers; electrode dimensions of the Bayard-Alpert ionization gauge and its sensitivity; and analysis of the changes in Pirani gauge characteristics are also deliberated in this text. This volume is beneficial to students and researchers conducting work on vacuum, including other related subjects such as etymology, electromagnetism, and quantum mechanics.

Book Description
Diamond films grown by activated chemical vapor deposition have superlative thermal, mechanical, optical, and electronic properties combined with a very high degree of chemical inertness to most environments. These properties, together with the ability to fabricate films and shapes of considerable size, promise an exciting new material with many applications. Some applications are on the verge of commercialization but many await a few more technological developments. Diamond-like films are already employed in both commercial and military applications. The popular press, as well as the scientific and technological and industrial communities, are increasingly interested in the potential for future development of these materials. Although there are many technical papers and review articles published, there is no Single comprehensive introduction to these technologies. The Scientific Affairs Division of NATO recognized the need and the future importance of these technologies and authorized an Advanced Study Institute on diamond and diamond-like films. NATO Advanced Study Institutes are high level teaching activities at which a carefully defined subject is presented in a systematic and coherently structured program. The subject is treated in considerable depth by lecturers eminent in their fields and of international standing. The presentations are made to students who are scientists in the field or who possess an advanced general scientific background.

Book Description
This is a comprehensive text describing the basic physics and technological applications of vacuum arcs. Part I describes basic physics of the vacuum arc, beginning with a brief tutorial review of plasma and electrical discharge physics, then describes the arc ignition process, cathode and anode spots which serve as the locus for plasma generation, and resultant interelectrode plasma. Part II describes the applications of the vacuum arc for depositing thin films and coatings, refining metals, switching high power, and as sources of intense electron, ion, plasma, and x-ray beams.
