It will accelerate 50mA CW deutron beam from 50keV to 1MeV at 162.5MHz. The novel structure of four-vane with window was used to seperate the dipole mode from the working mode. The field tuning of this RFQ was different from conventional four vane RFQ because that the four quadrants of RFQ cavity were coupled. The discipline of field tuning was studied by simulation and experiment. The beam dynamics of the RFQ was designed by equipartation and matching method, limit current effect was considered at the same time. The final design result of the RFQ was: voltage between electrodes was 60kV, transport efficiency of RFQ is 98%, field unflatness is less than 2% after tuning, the deformation of RFQcavity is less than 80um. Only 47 hours was spent to increase CW power of cavity from 0 to 55kW in high power test and The RFQ can working stable at the design voltage. The preliminary H²⁺ beam exeperiment has been done and 1.78mA CW beam was obtained at exit of RFQ. This paper will introduce the detail of design and experiment of the RFQ.
