Final Report on the Advanced Acceleration Techniques Working Group , T 8

There is a small but vigorous community working on advanced accelerator concepts in the United States. This effort, principally supported by the DOE, is deemed important for the long term vitality of High Energy Physics (HEP). In addition, the program contributes essential technology and accelerator science to the benefit of all fields using accelerators in their research. Although the research is not directed at any particular project, such as the NLC, its long term focus, i.e., 10 years or more, is to advance the state-of-the-art for HEP. It addresses fundamental issues which could lead to new or improved, high-gradient accelerators, rf sources, computational techniques, beam control devices and new diagnostic tools. The advanced accelerator research provides an exciting and stimulating field of physics, which continues to attract young and talented researchers. This community is also responsible for a large number of high quality scientific publications and is invaluable as a training ground for new Ph.D. students. Over 80 invited talks were presented within the T8: Advanced Acceleration Techniques Working Group. These talks highlighted the recent progress, developments and results in the field.
