| TUPCF04 | Feedback Controller Development for the APS-MBA Upgrade | 203 |

||
| The Advanced Photon Source (APS) is currently in the preliminary design phase for the multi-bend achromat (MBA) lattice upgrade. Broadband Root Mean Square (rms) orbit motion should stay within 10% of a beam cross-section of the order 4μm x 4μm rms at the insertion device source-points. In order to meet these stringent AC beam stability requirements, a new orbit feedback system is under development and is being tested on the existing APS storage ring. The controller prototype uses Commercial Off-The-Shelf (COTS) hardware that has both high-performance Xilinx Field-Programmable Gate Array (FPGA) and two high-performance Texas-Instruments Digital Signal Processors (DSP) onboard. In this paper, we will discuss the rationale for a combined DSP/FPGA architecture and how functions are allocated. We then present the FPGA architecture and the results of using Infinite Impulse Response (IIR) filtering to mitigate Beam Position Monitor (BPM) switching noise and aliasing. | ||
