Surface physics has experienced in the last decades an explosive expansion caused by the development and/or substantial improvement of surface sensitive techniques and UHV apparatuses. It has grown into a mature field of research, with data of the highest accuracy and reproducibility. Surface physics is of great importance for technological applications like field effect devices, molecular beam epitaxy, chemisorption and catalysis, corrosion, surface hardening etc. The present volume III/24 is restricted to the so-called "clean" surfaces, i.e. to surfaces atomically clean and well characterized, leaving the more complex field of the contaminated surfaces and overlayers to a later occasion.

Early in 1989, while most of us were gathered in the Mediterranean five-centuries-old city of Alacant, the idea of a school on stopping and particle penetration phenomena came to our minds. Later that year when discussing this plan with some of the participants in the 13th International Conference on Atomic Collisions in Solids in Aarhus, we were pleased to note that the proposal was warmly welcomed indeed by the community. An Advanced Study Institute on this or a related subject had not been organized in the last decade. Because of the progress made particularly in the interaction of high energy beams with matter, and the many applications which the general subject of the stopping of charged particles (ions and electrons) in matter enjoys, a Study Institute appeared a worthy enterprise. Even though several international conference series cover developments in these areas, they miss tutorial introductions to the field. The title chosen was Interaction of Charged Particles with Solids and Surfaces, and the objectives were stated as follows: "to cover theory and experiments, including selected applications and hot topics, of the stopping of charged particles (ions and electrons) in matter. The emphasis will be on outlining the areas where further effort is needed, and on specifying the basic needs in applications. Fundamental concepts will prevail over applications, and the character of the Institute as a school will be stressed. " The school was directed by Fernando Flores (Spain), Herbert M. Urbassek (Germany), Nestor R.

On attending a conference on the Jovian satellites at UCLA, I heard Lou Lanze rotti vigorously present the exciting data on the sputtering of water ice by Me V protons taken with W. L. Brown at AT&T Bell Labs. In his inimitable way he made clear that this new electronic sputtering process was very poorly under stood and was very important for surface properties of sattelites. I was immedia tely hooked, and have been working ever since with Lanzerotti, Brown, my col league at Virginia, John Boring, and Bo Sundqvist at Uppsala on understanding the ejection of material from surfaces and applying laboratory results to intere sting planetary problems. In the course of writing this book I also had the benefit of spending a semester with the Planetary Geosciences group in Hawaii, thanks to Tom McCord, a period of time with Doug Nash at JPL, and a period ot time with the group at Catania. The book was started with the encouragement of Lou Lanzerotti. The writing has gone slowly as the field has been changing rapidly. Even now I feel it is incom plete, as the interesting Halley dust data have just recently been interpreted in detail, Voyager has recently visited Neptune, and the data on Pluto are rapidly improving. However, most of the principles for plasma ion alteration of surfaces and gases have been established allowing, I hope, a coherent and useful frame work for incorporating both new laboratory and planetary data.

Building on Mozumder's and Hatano's Charged Particle and Photon Interactions with Matter: Chemical, Physicochemical, and Biological Consequences with Applications (CRC Press, 2004), Charged Particle and Photon Interactions with Matter: Recent Advances, Applications, and Interfaces expands upon the scientific contents of the previous volume by cover
