Abstract

A beam diagnostic system, which is based on capacitive beam-position monitors combined with fast electronics, has been developed. The position signal of each monitor is digitized at an adjustable sampling rate, and the most recent 8192 position and intensity values are buffered. This allows a wide range of different beam diagnostic measurements. The main purpose is the closed-orbit correction, which can be carried out on various time scales. To optimize the duty factor of the extracted beam, the system can be used as a fast relative intensity monitor resolving the intensity distribution of the bunches or of the injected beam.<>
