| 英文摘要 | RF system of K-500 Super-conducting Cyclotron at VECC is a complex three phase system operating in the frequency range of 9 MHz to 27 MHz with maximum acceleration potential of around 100KV feeding to each of three Dee cavities placed in median plane of cyclotron 120º apart through coupling capacitors. Each phase consists of chain of amplifiers and resonator operating in synchronization and at final stage of each phase, high power water cooled Tetrode Tube (Eimac4CW150,000 E) is used as high power amplifier each capable of delivering 80 KW of RF power. Individual power supplies for biasing Anode, Filament, Grid and Screen for all three high power Tetrode Tubes are designed and developed in house. Anode supply is common to all three tubes, rated at 20KV, 22 Amp, 450 kW along with fast acting crowbar protection using Ignitron. All these power supplies are commissioned and have been in operation for more than one year successfully. This paper describes about the technical aspects of the power supplies for RF Amplifier Tubes and special features of protection systems. |
