Abstract
The 100 MeV Proton linear accelerator (Linac) for the PEFP (Proton Engineering Frontier Project) will include one RFQ and one DTL1 at 350 MHz as well as seven DTL2 cavities at 700 MHz. The low level RF system with the digital feedback RF control provides the field control to accelerate a 20mA proton beam from 50 keV to 20 MeV with a RFQ and a DTL1 at 350 MHz. The FPGA-based digital feedback RF control system has been built and is used to control cavity field amplitude within ± 1% and relative phase within ± 1°. The fast digital processing is networked to the EPICS-based control system with an embedded processor (Blackfin).
