Description
Radio frequency resonant cavity beam position monitors (CBPMs) offer stable nano-meter scale (10s to 100s nm) resolution measurement of transverse beam positions in particle accelerators. The performance of these devices depends critically on system considerations, such as calibration and operation. This talk outlines the main issues with stably operating CBPMS, RF processing, calibration and beam position jitter subtraction. Examples are taken from the Accelerator Test Facility 2 (ATF2) an ILC/CLIC test accelerator which has to date produced the worlds smallest electron beam of approximately 47 nm.
