09:15 → 10:15 Powering CLIC, Strategies and Technical Issues

CLIC is a machine that will require a tremendous amount of power converters for supplying, among others, its magnets and klystrons. This talk will present several sectors with their powering strategies and the technical issues that are expected. The drive beam decelerator, contains about half of the total amount of magnets in the whole machine. A powering scheme using groups of serial connected magnets and small current trimmers will be presented. Efforts have been made to improve the overall machine availability by implementing redundant converters and a failure tolerant operation strategy. The powering of the drive beam Linac constitutes itself about half of the total power consumption. Moreover, the modulators for the Klystrons have requirements that have never been reached so far. The technical issues and a roadmap for future research will be given. Finally, the ongoing work on the identification of power converters for all CLIC magnets will show the grouping strategy we want to adopt. The uniformity in the CLIC magnets regarding their needs in current will allow to reduce the number of power converter families and improve the management of spares.

Speaker: Daniel Siemaszko
