In order to further meet the needs of major national strategies and basic scientific research, High Energy Photon Source (HEPS) will be a high-performance fourth-generation synchrotron radiation source in Beijing, which will build more than 90 high-performance beamline stations. In order to ensure the high-performance operation of each beam line, the stability of the beam orbit near the light source output point is extremely important. As one of the key guarantees for the stability of the electron beam orbit, The FOFB system can suppress the beam orbit disturbance within a certain bandwidth to an acceptable range. This article introduces the currently progress of the FOFB system, including: the overall architecture scheme and key technical routes; the substation design following the ATCA mechanical architecture; the BPM data acquisition and high-speed transmission using high-performance Rocket I/O transmission Mechanism; embedded high-performance DSP for fast multiplication calculation to realize SVD, etc. The entire system design is progressing in an orderly manner.

The fast protection system for CSNS accelerator is a FPGA based protection system. The VME bus and SFP was adopted by the FPS. The FPS includes one central station and several sub-stations, and connnections between the central and the sub-stations are in star style. Two kinds of beam stopping modes are designed and implemented by FPS, one is the transient beam stopping and auto recovery mode, the other is the permanent beam stopping mode. The measured response time for the FPS is less than 1.5 micro-seconds.
