Design of RF generator at cooling storage experimental ring

RF system of HIRFL-CSRe(cooling storage experimental ring) was designed by ourselves and manufactured domestically, which operates in the frequency range of 0.5~2.0 MHz at first and second harmonic modes. Based on detailed engineering calculation, the design of RF generator was completed. It will work not only in CW mode but also in the mode of ramping pulse modulation, and the maximum power is up to 70 kW. It satisfies the requirement of 10 kV maximum deceleration voltage to capture the irradiative beam and decelerate the beam from 400 MeV/u to 30 MeV/u.
