PPT-Breakdown positioning in CLIC prototype RF accelerating structures

CLIC workshop 2016 R Rajamäki W Farabolini J Giner Navarro T Argyropoulos B Woolley W Wuensch 19012016 Aalto university CERN Introduction What Localize BDs in RF accelerating structures. What makes relationships successful?. Successful. Unsuccessful. Relationships are like car accidents (Steve Duck, 2007). The breakup is the drivers’ fault. The breakup is because of mechanical failure (lack of maintenance). Engineering Development update. Norbert Collomb, STFC Daresbury Laboratory. 1. N. Collomb. 13/09/2012.
