No. 32 (2003): Accelerating structures of linacs for future electron-positron linear colliders

Issue Editor: J. Gao, Editors-in-Chief: W. Chou and J.M. Jowett

Since 1995 the newsletter has been published at a rather constant rhythm of three issues per year (there was a break in publication of about four years before the newsletter was revived by the editors of No. 7). Some recent issues have been quite a bit thicker and contained more detailed material than the earlier ones.

Accelerating structures of linacs for future electron-positron linear colliders, which is one of the main axes of research efforts of international particle accelerator community, have been chosen as the main subject of this issue. Reports from TESLA, GLC, NLC and CLIC reflect their state-of-the-art technological advances and challenges. As contra-balance, we have invited ICFA Panel on Advanced and Novel Accelerators headed by Dr. W. Leemans to provide us information on the progresses of advanced and novel accelerating possibilities, which are not the simple extrapolations from the well known particle accelerating technologies (in this issue we publish the first part of the contributions, and the second part will be appeared in the next issue). As a pivot, we have collected reports from the workshops focused mainly on the problems in storage ring colliders, which represent the main powerful operational facilities for the particle physics researches of our community nowadays. It is with the above mentioned global view that authors are invited, contributions are structured and presented. Finally, I hope, as editor, that readers of this issue benefit not only from the single contribution effect, but also from the global collective effect of this issue.
