Neutron availability in the Complementary Experiments Hall of the IFMIF-DONES facility

International audience•We show that IFMIF-DONES has the potentiality to be a competitive multi-purpose medium-flux neutron facility•A large range of non-fusion experiments will be possible at the IFMIF-DONES facility•A fast neutron beam will be available with a flux of about 21010 n/cm2/s•Thermal neutron fluxes can also be obtained with moderators but limited to a maximum in the range of about 107 n/cm2/s The IFMIF-DONES facility will be dedicated to the irradiation of structural materials planned for the use in future fusion reactors such as DEMO (Demonstration Fusion Power Plant). The potentialities of the IFMIF-DONES facility to complement its principal purpose by other experiments that would open the facility to other communities is addressed in this work. It concerns a study based on simulations to evaluate the neutronic performances of IFMIF-DONES in an hall dedicated to complementary experiments where neutrons can be transported. With the simple beam tube geometry of 4.5 cm entrance diameter studied in this work we have shown that a collimated fast-neutron beam of about 2 1010 n/cm2/s is available in the hall. Adding a moderator in the hall with neutron extraction lines would allow to get thermal neutron beams of about  106-107 n/cm2/s for dedicated experiments. The results show that IFMIF-DONES has the potentialities to be a medium-flux neutron facility for most of the neutron applications
