Beam position monitoring system for the 1.5 GeV transport line of NSRRC

The extracted 1.5 GeV electron beams from the booster synchrotron are transported via a transport line and injected into the storage ring. This booster-to-storage ring transport line equipped with seven stripline beam positions monitors. Commercial log-ratio BPM electronics were adopted to process the 500 MHz bunch signal directly. The position of the passing beam is digitized by VME analog interface. This report addresses the system architecture, software tools, and performance of the BTS trajectory measurement. This system will provide an elegant tool for optimizing the performance of the transport line. Preliminary results and possible applications are included.
