	Digital beam position monitor (DBPM) system is one of the most important beam diagnostic instruments generally used in modern accelerators. The performance of DBPM is mainly given by its digital signal processing algorithm. In order to find out a better solution for our new DBPM system, two algorithms have been designed and implemented on a commercial FPGA based DAQ module (ICS1554) to retrieve the turn-by-turn (TBT) data. The first algorithm is based on frequency mixing, and the second one on discrete Fourier transform (DFT). Laboratory tests show that the standard deviation of measured positions can be better than 1μm at 5 dBm with input signal stronger than 5 dBm for both algorithms. And on-line evaluation indicates that real beam motion can be observed correctly using either algorithm.

MOP183	First Measurements of a New Beam Position Processor on Real Beam at Taiwan Light Source	injection, betatron, controls, storage-ring	429

	Libera Electron, Libera Brilliance and Libera Brilliance⁺ compose the electron beam position processors product family, which covers the needs of wide variety of the circular light source machines. The instruments deliver unprecedented possibilities for either building powerful single station solutions or architecting complex feedback systems. Compared to its predecessors (Libera Electron and Libera Briliance), the latest member of the family Libera Brilliance⁺ allows even more extensive machine physics studies to be conducted due to large data buffers and the new true turn-by-turn position calculation. It offers a large playground for custom- written applications with VirtexTM 5 and COM Express Basic module with Intel Atom N270 (x86) inside. First field tests of the new product were performed on real beam at Taiwan Light Source (TLS). The test setup, measurements and results are discussed in the paper.
