The SPIRAL2 linac starts its beam commissioning at GANIL. The project is finishing the superconducting linac installation and commissioning. In parallel, the first source beam has been produced in 2014. The light and the heavy ion sources have already produced their expected beam performances. The RFQ conditioning started in October 2015, and the beam commissioning soon after that. After having briefly recalled the project scope and parameters, the RFQ beam commissioning ranging from 5mA CW proton beamto 1mA Q/A=1/6 will be presented.
