Workshop home page

The formal proceedings will be published as a CERN Yellow Report and will only include written contributions. The contributions should be submitted to by 31 October 2002 and should be formatted with a recent official template from EPAC/PAC/APAC. There is no page limit. The web proceedings provide electronic access to most presentations at the workshop.
