Funding: Proton Engineering Frontier Project, Korea Atomic Energy Research Institute, Ministry of Education, Science and Technology of the Republic of Korea. PEFP developed a 120-keV RF cavity for their ion implantation applications. Due to ambient disturbances, the cavity’s resonance frequency may vary in long-term test. We designed a digital control system to change the frequency of the RF sources for tracking the cavity’s frequency variations. The digital control system has functions such as, phase shift, phase comparison, proportional-integral compensation, waveform generation and frequency/pulse modulation, and driving signal generator. Most of them are implemented digitally in a Virtex II 4000 Field Programmable Gate Array (FPGA). In this research we show the design and the preliminary test results of the digital control system. * Work supported by the Ministry of Science and Technology |
