The SPIRAL2 88 MHz CW RFQ is designed to accelerate light and heavy ions with A/Q from 1 to 3 at 0.73 MeV/A. The nominal beam intensities are up to 5 mA CW for both proton and deuteron beams and up to 1 mA CW for heavier ions. The design foresees almost 100% transmission for all ions at nominal beam current and emittance. Beam commissioning of the RFQ and linac cool down started already. The specifications have been achieved within the measurement precision for the different ions accelerated yet. This paper describes the beam commissioning strategy, the measurement results in both transverse and longitudinal planes and the success-fully first cryogenic tests of the linac.
