  IFMIF, the International Fusion Materials Irradiation Facility, will learn the degradation of the mechanical properties of purpose designed reduced activation ferritic-martensitic steels under bombardment of 14 MeV neutrons at 1018 n/m2s flux reaching values of 150 displacements per atom in the steel lattice. The understanding of the impact of Deuterium-Tritium fusion neutrons in next decade is essential to design and construct a fusion power plant; the next step after ITER. The 14 MeV neutrons are stripped from a liquid Li screen flowing at 15 m/s impacted by 2 parallel 125 mA deuteron beam at 40 MeV. IFMIF project, in its engineering validation phase, will operate in Rokkasho a 125 mA deuteron LINAC at 9 MeV that will validate the concept of IFMIF accelerator, LIPAc. The ion source will inject 140 mA deuterons at 100 KeV in a normal-conducting RFQ that will deliver the bunched beam at 5MeV to be accelerated up to 9 MeV thanks to 8 half-wave superconducting resonators. The installation and commissioning of LIPAc in Rokkasho (Japan) is sequential and the first stage is starting now; the strategy to overcome potential difficulties is detailed.
