| 英文摘要 | Radio frequency system of Superconducting cyclotron at VECC, Kolkata, has been developed to achieve accelerating voltage of 100 kV max. With frequency, amplitude and phase stability of 0.1 ppm, 100 ppm and ±0.5o respectively in the frequency range of 9 – 27 MHz. Each of the three half-wave coaxial cavity is fed with rf power (80kW max.) from each of the three high power final rf amplifiers based on Eimac 4CW150,000E tetrodes. Initially, the whole three-phase RF system has been tuned for operation with RF power to the cavities at 19.1994 MHz and thereafter commissioned the cyclotron with neon 3+ beam at external radius at 14.0 MHz. In this paper, we present brief description of the rf system and behaviour observed during initial conditioning of the cavities with rf power and the way to get out of multipacting zone together with discussion on our operational experience. We have so far achieved dee voltage up to 57 kV at 14 MHz with 20 kW of RF power fed at each of the three dees and achieved vacuum level of 4.5 x 10-7 mbar inside the beam chamber. We also present discussion on the problems and failures of some RF components during commissioning stage and rectifications done to solve the same. |
