This volume is based on the lectures at the NATO Advanced Study Institute, entitled "Advanced Technologies Based on Wave and Beam Generated Plasmas", held at Sozopol, Bulgaria, from May 22 till June 1, 1998. It attracted almost 100 participants from 16 different countries. The meeting combined different types of scientists from advanced experts to aspiring young researchers. It aimed at stimulating future development by providing-across borders- cross-fertilization and exchanges between previously unconnected groups. This is reflected in the contents of the volume which covers the lectures given. The book also contains in a second part 43 poster presentations mostly from younger participants with valuable complementations and specifica­ tions to the lectures. With its topics the Advanced Study Institute constitutes the first attempt to bring together in an organized manner three areas of work on plasma technologies: advanced efforts based on wave generated---high frequency-····plasmas, on plasma assisted ion implantation and on electron beam generated plasmas.
