  A Single Spoke cavity has been designed for Chinese Accelerator Driven System(C-ADS) Project at IMP. In this paper, we describe the geometric and mechanical optimization of Single Spoke Cavity ,using 3D software CST-MWS and ANSYS. The goal of optimization is to minimize the ratio of Bpk/Eacc and Epk/Eacc, maximize G*R/Q. Finally, some analysis of Power coupler are also presented.

  The Development of the Half Wave Resonator (HWR010) is based on the China ADS. The HWR010 operates at 162.5 MHz and can provide more than 0.78 MV of accelerating voltage per cavity for proton withβopt=0.10. We have designed the HWR010 in 2011. A copper model has been fabricated to test the HWR fabrication procedure. Five HWR010s have been fabricated in 2012. The HWR010s has finished the vertical testing and the Q0 is 4·108 at Epeak = 45 MeV/m, and one of the HWR010s has been vertical tested with helium vessel. The slow tuner and high power coupler for this HWR have been developed and tested.

Within the framework of the C-ADS project, IMP has proposed a 162.5MHz HWR Superconducting cavity for low energy section(β=0.09) of high power proton linear accelerators. A compact slow tuner has been developed for final tuning of the resonance frequency of the cavity after cooling down to operating temperature and to compensate microphonics and Lorentz force detuning. The slow tuner is driven by an external stepper motor and gear box for coarse cavity adjustment. To reduce the force requirements of the actuator, a lever arm and scissor jack mechanism have been applied. The tuner design and recent results of warm tests as the first prototype are presented.
