  The LIPAc accelerator aims to operate 125 mA/CW deuteron beam at 9 MeV to validate IFMIF's accelerators that will operate in CW 125 mA at 40 MeV. The different subsystems of LIPAc have been designed and constructed mainly by European labs and are being installed and commissioned in Rokkasho Fusion Center. The 2.45 GHz ECR injector developed by CEA-Saclay is designed to deliver 140 mA/100 keV CW D+ beam with 99% gas fraction ratio. Its LEBT presents a dual solenoid focusing system to transport and match the beam into the RFQ. Its commissioning continues in 2016 in parallel with the RFQ installation. The normalized RMS emittance at the RFQ injection cone is to be within 0.25π mm·mrad to allow 96% transmission through the 9.81 m long RFQ. In order to avoid activation during commissioning, an equal perveance H+ beam of half current and half energy as nominal with deuterons is used. In this article, the commissioning results with 110 mA/100 keV D+ beam and 55 mA/50 keV H+ beam are first reported.
