Currently, 2 Hz slow orbit feedback (SOFB) system is operating, and 1 kHz fast orbit feedback (FOFB) system is installed recently. This FOFB system is consists of 96 electron beam position monitors (BPMs), 48 horizontal fast correctors, 48 vertical fast correctors and VME control system. We present the design and implementation of the FOFB system and its test result. Analysis through the simulation is presented and future improvement is discussed PB - JACoW CP - Geneva, Switzerland SP - 2667 EP - 2669 KW - feedback KW - electron KW - storage-ring KW - operation KW - timing DA - 2016/06 PY - 2016 SN - 978-3-95450-147-2 DO - 10.18429/JACoW-IPAC2016-WEPOR004 UR - http://jacow.org/ipac2016/papers/wepor004.pdf ER -
