INTEGRATION OF NEW D IGITAL BPM IN THE TAIWAN LIGHT SOURCE

Integration of new generation digital beam position monitor (DBPM) was performed recently. The BPM electronics are commercial available by using direct RF sampling technolog y, FPGA, and embedded control environment running GNU/Linux. The implementation is emphasized on control system integration and compatible with existing system to enhance functionality and performance of the BPM system. The programmable nature of DBPM system is beneficial for multi-mode high precision beam diagnostics purposes. Sub-micron resolution is achieved for averaged beam position measurement. Medium resolution is obtain for turn-by-turn beam position measurement. Tune and other diagnostic measurements are also supported. The DBPM are seamless integrated with existed control system. System structure and preliminary te st results will presented in this report.
