Description

The CSNS-II superconducting Linac accelerator includes 20 sets of 324 MHz superconducting spoke cavities and 24 sets of 648 MHz superconducting ellipsoidal cavities. The 324 MHz/300 kW solid-state power source supplies RF power to superconducting spoke cavity, while the 648 MHz/1.2 MW klystron power source supplies RF power to superconducting ellipsoid cavity. The 324 MHz/300 kW solid-state power source uses GaN amplifier tubes and is composed of two cabinets. The long-pulse solid-state modulator supplies pulsed high voltage to the 648 MHz/1.2 MW klystron. The RF pulse width is 1.2 ms, the repetition rate is 50 Hz.
