Energy recovery linacs (ERL) is promising to achieve high average current with superior beam quality. The key component for accelerating such high current beams is the superconducting radio frequency (SRF) cavity. The design of a 1.3 GHz 5-cell high current superconducting cavity has been carried out under the cooperation between Peking University (PKU) and Argonne National Laboratory (ANL). RF properties, damping of the HOMs, multipacting and mechanical features of this cavity have been discussed and the final design is presented.

  A 1.3 GHz 3.5 Cell LG niobium cavity is installed for the new PKU DC-SC injector as its accelerating cavity with working temperature is 2K. High amplitude and phase stability is required for the updated SRF photocathode injector. This paper describes the design of Low Level RF control system based on FPGA, including hardware and software,and the communication function is realized by Tri-State Ethernet. The system should be operated on the precision with the amplitude of ±0.1% and phase stability of ±0.1°.
