DB-BPMMB-BPMWake Field MonitorsDB-BPM4Drive beam BPMQuadBPMWPSPETS 130MWBase line scenarioThe drive beam quadrupole and BPM are mounted on the drive beam girders. BPMs cannot be moved independently of the PETS, the quadrupoles will either be on movers, or equipped with dipole corrector coils. The BPMs are mounted before quadrupoles. The acceptable level of wake field needs to be determined.CLIC09 Workshop 12-16 October 2009Lars Sby 5Drive beam BPMsBPM20m2m?
