The International Fusion Materials Irradiation Facility (IFMIF) aims at providing a very intense neutron source (1017 neutron/s) to test the structure materials for the future fusion reactors, beyond ITER (International Thermonuclear Experimental Reactor). Such a source will be driven using 2 deuteron accelerators 125 mA cw up to 40 MeV impinging into a lithium liquid curtain, thus producing very high neutron flux with a similar spectrum as those expected in fusion reactors. A validation phase was decided for this 10 MW facility consisting partly in the design of the prototype accelerator LIPAc (Linear IFMIF Prototype Accelerator). LIPAc, which is in design phase, will accelerate a 125 mA cw beam deuteron up to the first superconductive linac module (4 for IFMIF). The 9 MeV beam will be driven through a HEBT to beam dump. This facility is currently under construction at Rokkasho (Japan). We propose to describe the beam diagnostics foreseen for this 1.125 MW accelerator emphasizing the challenges encountered and the overcome solutions, if any.
