  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.

The baseline design for the first stage of the ESS-Bilbao proton linear accelerator up to 50 MeV is almost concluded and the linac is at present under construction. Three main application laboratories have been envisaged in this first stage: two proton irradiation laboratories and a low intensity neutron source. In particular, the high intensity proton beam of 50 MeV will be used to test structural materials for fusion reactors* under project named “Protons for Materials” (P4M), described in this contribution. The P4M irradiation room will be an underground facility located at the accelerator's tunnel depth. High levels of activation are expected in this irradiation room and its design presents challenges in both remote handling and independent operation from the other two surface laboratories. Thermal analysis of the beam power deposition over the target will be presented.
