The SPIRAL2 RFQ is designed to accelerate at 88MHz two kinds of charge-over-mass ratio, Q/A, particles. The proposed injector can accelerate a 5 mA deuteron beam (Q/A=1/2) or a 1 mA ion beam with Q/A=1/3 up to 0.75 MeV/A. It is a CW machine which has to show stable operation, provide the requested availability, have the minimum losses in order to minimize the activation and show the best performance/cost ratio. It will be a 4- vane RFQ type, with a mechanical assembly, the global goal being to build an RFQ without any brazing step. Extensive modelisation was made to ensure a good vane position under RF. A 1-m long hot model prototype is under construction in order to validate the manufacturing concept.
