Recent scientific and technical advances have made it possible to create matter in the laboratory under conditions relevant to astrophysical systems such as supernovae and black holes. These advances will also benefit inertial confinement fusion research and the nation's nuclear weapon's program. The report describes the major research facilities on which such high energy density conditions can be achieved and lists a number of key scientific questions about high energy density physics that can be addressed by this research. Several recommendations are presented that would facilitate the development of a comprehensive strategy for realizing these research opportunities.

Laser and Electron Beam Processing of Materials contains the papers presented at the symposium on "Laser and Electron Beam Processing of Materials," held in Cambridge, Massachusetts, in November 1979, sponsored by the Materials Research Society. The compilation presents reports and research papers on the use of directed energy sources, such as lasers and electron beams for materials processing. The majority of the materials presented emphasize results on semiconductor materials research. Substantial findings on research on metals, alloys, and other materials are presented as well. Topics covered by the papers include the use of scanned cw sources (both photons and electrons) to recrystallize amorphous layers, enhanced substitutional solubility, solute trapping, zone refining of impurities, and constitutional supercooling. The use of lasers and electron beams to anneal ion implant damage and contacts formation, processing of ion-implanted metals, and surface alloying of films deposited on metallic surfaces are also discussed. Metallurgists, engineers, and materials scientists will find the book very insightful.

The development of advanced materials with preselected properties is one of the main goals of materials research. Of especial interest are electronics, high-temperature and supemard materials for various applications, as well as alloys with improved wear, corrosion and mechanical resistance properties. The technical challenge connected with the production of these materials is not only associated with the development of new specialised preparation techniques but also with quality control. The energetic charged particle, electron and photon beams offer the possibility of modifying the properties of the near-surface regions of materials without seriously affecting their bulk, and provide unique analytical tools for testing their qUality. This volume includes most of the lectures and contributions delivered at the NATO-funded Advanced Study Institute "Application of Particle and Laser Beams in Materials Technology", which was held in Kallithea, Chalkidiki, in Northern Greece, from the 8th to the 21st of May, 1994 and attended by 73 participants from 21 countries. The aim of this ASI was to provide to the participants an overview of this rapidly expanding field. Fundamental aspects concerning the interactions and collisions on atomic, nuclear and solid state scale were presented in a didactic way, along with the application of a variety of techniques for the solution of problems ranging from the development of electronics materials to corrosion research and from archaeometry to environmental protection.

Although the history of photomedicine dates back thousands of years, with even preliterate cultures appreciating the healing properties of sunlight, for many workers in the discipline photomedicine is associated with the observation about 100 years ago of Niels Finsen, a Danish physician. Finsen recognized that people with tuberculosis who lived in Norway and who had very little exposure to sunlight often developed facial lesions (lupus vulgaris) which would decrease and sometimes disappear during the summer months. This very observant physician reasoned that artificial light ought to produce the same effect as sunlight and began utilizing the radiation from the newly available carbon arc. At first, he used a glass lens to concentrate the radiation, but since this produced considerable burning, he replaced this with a hollow glass lens filled with water. However, while this reduced the heat burns, it did not actually duplicate the effect of direct sunlight. Finally, using a hollow lens filled with water but equipped with quartz windows, Finsen was able to imitate, even improve upon, the effect of sunlight. As a result, lupus vulgaris was practically eliminated from the Scandinavian countries.
