Material testing via irradiation in high energy and high neutron fluxes is of a great interest for very extended community working on nuclear waste transmutation (use of ADS in particular), intensive neutron sources (SNS, ESS, �), radioactive ion beam (RIB) production with neutrons (EURISOL, RIA, �), future controlled fusion experiments and reactors (ITER, DEMO, �), space applications (resistance of electronics, shielding, �), etc. In this paper we will characterise in more detail the potential of using SPIRAL-2 neutrons in this context. A huge number of high energy neutrons (in the range between 1 and 40 MeV) produced in the carbon converter via C(d,xn) reaction will be present at SPIRAL-2 and in principle could be used for other purposes than RIB production. Mainly two different utilisation methods have been investigated: material irradiation very close to the target-converter and time-of-flight measurements with a pulsed neutron beams. Below we present only the case of material irradiation with energetic neutrons.
