The RFQ, which operated under CW mode, is specified to accelerate 10 mA deuteron beam from the energy of 20 keV/u to 1.5 MeV/u. To reduce the possibility of beam loss in supper conducting section, the output longitudinal emittance need be optimized. The idea of 'Kick-drift' is adopted in beam dynamic design. The challenge for CW RFQ is not only the beam dynamic design but also in the design of cavity structure and cooling of structure. With the experi-ence obtained in the design of the RFQ for CIADS injec-tor II, the structure design and cooling design have been finished. The results of low power RF measurement show the flatness and asymmetry are below 4% for each mod-ule.
