First ILC Workshop

WG 5: High-Gradient Cavities

Topics

Discuss about the accelerating cavities, in particular establishing the baseline performance and going beyond it.

In Short...

Program (Annotated: 08:22, Nov.15, 2004)

All presentations are to be made with computer projectors. OHP presentations are not supported. Please, make sure to give a copy of your presentation files to the WG scientific secreatry (the name shown at the bottom of this page) who carries a USB memory stick.
