  Material irradiation by protons is capable of simulating the effects of fusion neutrons (14 MeV, target damaging and He & H production) with a reasonably fast dose rate, according to theoretical calculations and previous experiments. Therefore, given that the ESS-Bilbao (ESS-B) accelerator, under construction in Bilbao, will provide an intense source of 50 MeV protons, with total currents of a few mA’s, a laboratory for fusion material testing is proposed. This paper appraises the scientific feasibility of performing fusion relevant experiments in the proposed laboratory. Material characterization under proton irradiation (by in-beam techniques to assess mechanical properties) while monitoring mechanical, micro-structural and compositional changes of the irradiated materials are some of the laboratory goals. Special emphasis is placed on expected radiation damage parameters in structural and functional materials, the beam power deposition in the sample and the consequences of material activation for the laboratory design.
