HG2006

chaired by Walter WUENSCH (CERN)

from Monday, 25 September 2006 at 08:00 to Wednesday, 27 September 2006 at 17:00 (Europe/Zurich)
at CERN European Organization for Nuclear Research ( 40/S2-B01 )

Meyrin Switzerland

Description

High-Gradient 2006 RF Workshop at INDICO
The objective of the workshop is to bring the high-gradient rf community together to present and discuss recent theoretical and experimental developments. Significant progress has been made by a number of groups in recent years to understand the basic physics of rf breakdown and develop techniques for achieving higher gradients. We hope with this workshop to help maintain the momentum of this effort and to promote contacts and collaborations.
