Description

This item was taken from the IEEE Conference ' Development of the PEFP low level RF control system ' The RF amplitude and the phase stability requirements of the LLRF system for the PEFP (Proton Engineering Frontier Project) proton linac are within 1 % and 1 degree, 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 downconverted cavity signal frequency, digital in-phase and quadrature detection, pulsed mode operation with the external trigger, and a simple proportional-integral feedback algorithm implemented in a FPGA. The developed system was tested with 3 MeV RFQ and 20 MeV DTL, and satisfied the stability requirements.
