Summary
New linear accelerators need high precision beam offset measurements at dedicated position along the beamline. Resolutions below 1 µm are achievable by using Cavity Beam Position Monitor (CBPM) pick-ups for most of the used charge ranges. Since the beam distance at the European-XFEL will be at least 222 ns low-Q CBPMs are chosen to enable single bunch detection. The CBPMs for the European-XFEL are produced in the industry and tested at the FLASH facility with electronic prototypes. The principle of the design of the CBPM will be described followed by tests in laboratory and beam based.
