  The CSNS Linac is comprised of RFQ, two Buncher cavities, four DTL accelerators and one Debuncher cavity. The RFQ accelerator is powered by two 4616 vacuum tubes, the maximum output power of each tube is 350kW. Three 25kW solid state amplifiers supply RF power for two Buncher cavities and the Debuncher cavity, repectively. The RF power sources of four DTL accelerators are four 3MW klystrons. Each RF power source owns a set of digital LLRF control system in order to realize an accelerating field stability of ±1% in amplitude and ±1° in phase. The front four LLRF control systems have been used in the beam commissioning of CSNS Linac from the end of 2015. This paper will introduce the design and the performance of the LLRF control system.
