Description
The Proton radiation effects facility (PREF) was designed and constructed by the Institute of Modern Physics, which can provide high-quality proton beams with continuous and accurate tunable energy range, high current intensity, high duty cycle and large scanning area of 10-60MeV energy range. which consists of a proton source, RFQ linac injector, synchrotron and irradiation terminals. The RFQ works at 162.5 MHz, providing 1.2Mev proton beam for synchrotron. The RF system consists of a RFQ cavity, two 50 kW solid state amplifiers and digital low level RF control system (LLRF). The amplitude and phase stability requirements for the LLRF are 1% and ±1°separately. To meet requirements and to ensure reliability, a digital LLRF system was designed. The new digital LLRF is based on Virtex5 FPGA, fast ADCs and DACs, and CPCI bus. The progress and plans for future are presented.
