| The IFMIF-EVEDA accelerator will be a 9 MeV, 125 mA cw deuteron accelerator prototype for verifying the validity of the accelerator design for IFMIF. The RFQ, matching section and DTL resonant cavities must be fed with continuous RF power at 175 MHz frequency with an accuracy of 1% in amplitude and ± 1° in phase. Currently two possible solutions for the DTL design are considered. The first option consists of normal conducting (NC) Alvarez type cavities and the second option consists of superconducting (SC) Half Wave Resonator cavities. Both options impose different demands on the RF system which are analyzed in this paper. The RF power system will be made of several amplification stages and will be based on vacuum tube amplifiers. The main characteristics of RF system including those of the high voltage power sources required to feed the anodes of the high power tubes will be presented in this paper. |
