	The IFMIF aims to provide an accelerator-based, D-Li neutron source to produce high energy neutrons at sufficient intensity. Part of the BA agreement (Japan-EURATOM), the goal of the IFMIF/EVEDA project is to work on the engineering design of IFMIF and to validate the main technological challenges which includes a 125mA CW D⁺ accelerator up to 9 MeV mainly designed and manufactured in Europe. The components are in an advanced stage of manufacturing. The first components which allow the production of a 140 mA-100 keV deuteron beam have been delivered, installed and under commissioning at Rokkasho. The second phase (100 keV to 5 MeV) will end by March 2017. The third phase (short pulse) and forth phase (cw) will be the integrated commissioning of the LIPAc up to 9 MeV. The duration of the project has been recently extended up to end 2019 to allow the commissioning and operation of the whole accelerator (1MW). The aim of this paper is to give an overview of the LIPAc, currently under commissioning in Japan, to outline the engineering design and the development of the key components, as well as the expected outcomes of the engineering work, associated with the experimental program.

	The Drift Tube Linac (DTL) of the European Spallation Source (ESS) is designed to operate at 352.2 MHz with a duty cycle of 4% (3 ms pulse length, 14 Hz repetition period) and will accelerate a proton beam of 62.5 mA pulse peak current from 3.62 to 90 MeV. In this paper the DTL mechanical design and simulations are presented, together with the results obtained from the prototypes of three drift tubes, equipped respectively with Permanent Magnet Quadrupole, Steerer and Beam Position Monitor.

	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.
