| Abstract | The low level RF system is under development for the PEFP Proton Accelerator. The RF amplitude and phase stability requirements of the LLRF system are ±1% and ±1°, respectively. As a prototype of the LLRF, a simple digital PI control system based on commercial FPGA board is designed and tested. The main features are a sampling rate of 40 MHz which is four times higher than the down-converted cavity signal frequency, digital inphase and quadrature detection, pulsed mode operation with the external trigger, and a simple proportionalintegral feedback algorithm. The control logic is implemented in the Xilinx FPGA by using VHDL coding and the application program based on the VxWorks and VME platform is also developed. In this paper, the detailed design study and the test results of the prototype LLRF system are presented. |
