TI - FPGA Based Global Orbit Feedback in the Taiwan Light Source J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - The global orbit feedback for the 1.5 GeV electron storage ring of TLS has been operated more than ten years. This system uses general processors to control feedback loop with 1 kHz rate. It is very important for various operation of storage ring now, but some hardware components could have been out of stock in the future. As a prototype, a FPGA based fast global orbit feedback at a 10 kHz data acquisition rate has been developed. A micro-TCA liked platform with FPGA board is used to implement control algorithm and acquire BPM data from Libera Brillance. The correction algorithm is written in VHDL and connected to power supply with AURORA digital links. The system architecture will be discussed in this report.
