The X-Band Accelerating Structure Design and Test-Program Workshop

18 Jun 2007, 09:00 → 19 Jun 2007, 18:30 Europe/Zurich

AB AUDITORIUM M (CERN)

Walter WUENSCH (CERN)

REGISTRATION DEADLINE: 11 JUNE 2007

The CLIC design frequency and gradient have recently changed to 12 GHz and 100 MV/m. Since then the new base-line accelerating structure have been designing and the high-power testing program redefining. The aim of this workshop is to present assumptions and ideas to outside experts in order to provide general information, invite commentary and organize collaborations on structure design and high-gradient studies. Another objective of the workshop is to review testing possibilities worldwide, including test-structure fabrication and actual high-power testing.
