Abstract :
The beam orbit measuring system for the LNLS UVX ring is presented. The system consists of 24 strip-line beam position monitors and associated electronics. The beam position monitors (BPM´s) are capable of detecting down to 10 mA of stored beam current or 100 ns-long LINAC injection pulses (single pulse detection mode) with 0.05 mm resolution. Acquisition electronics is divided into two parts: four fast-acquisition channels for the pulsed mode operation (used during injection) and a single PIN-switch multiplexed channel for CW operation (closed orbit measurement). Experimental results obtained on a characterization bench are presented and compared with theoretical estimates
