Abstract

The layout of the SLS beam position monitor (BPM) system is presented. Since sub-micron position data in normal closed orbit and feedback mode as well as turn by turn information are required, the SLS BPM electronics pursues a new digital approach. The self calibrating four channel system consists of a RF front end, a digital receiver and a DSP controller. The whole system is integrated in the EPICS control system, which allows to select between different operation modes, so that the same BPM electronics applies to all the sections of the machine, namely linac, transfer lines, booster and storage ring. Mechanical drifts will be monitored by an independent measurement system and taken into account, when processing the final electron beam position
