The SPIRAL2 injector, made up of a 5 mA p-d ion source, a 1 mA heavy ion source (up to A/Q = 3) and a CW 0.75 MeV/u RFQ, has been commissioned in parallel with the superconducting linac installation. This com-missioning is successfully completed now and the Diag-nostic plate (D-plate) used to characterize the injector beams is removed. This paper presents the results ob-tained with the reference particles (H⁺, 4He2+, 18O6+ and 40Ar14+) and a comparison with the simulations. The connexion to the SC linac and the future linac beam commissioning is briefly described.
