Description
To meet the 500 kW target power of CSNS-II upgrade, a digital LLRF system is developed for the superconducting linear accelerator with 324 MHz spoke and 648 MHz elliptical cavities. An RFSoC-based hardware platform is adopted for direct RF sampling, robust control algorithm is implemented to suppress thermal drift, beam loading and Lorentz detuning. Cavity tests verify amplitude stability better than ±0.3% and phase stability within ±0.3°, satisfying the operational specification of the SRF linac.
